EXECUTIVE SUMMARY

IMPORTANT INTRODUCTORY NOTE

A further number of European States will start implementing 8.33 kHz channel-spacing from the 31st

October 2002. The switch from 25kHz to 8.33kHz channel-spacing in VHF voice communications isdesigned to increase the number of available frequencies. This will enable operational improvementssuch as airspace restructurisation to be supported.

The States participating in the 8.33 kHz Horizontal Expansion are: Bosnia & Herzegovina, Croatia,Czech Republic, Denmark, Estonia, Finland, FYROM, Hungary, Ireland, Italy, Latvia, Lithuania,Norway, Poland, Portugal, Slovak Republic, Romania, Slovenia, Spain, Sweden, United Kingdom andFR Yugoslavia. The majority of these States will remove their 8.33 exemptions from 31st OCT 2002.

Operators not strictly complying with the equipage and exemption requirements could compromisesafety. If such a situation arises, ATC will ensure that identified non-8.33 equipped traffic is kept clearof 8.33 sectors and will initiate the appropriate reporting action.

1. INTRODUCTION

1.1 8.33 kHz HORIZONTAL EXPANSION

1.1.1 A further number of European States will start implementing 8.33 kHz channel-spacing fromthe 31st October. The switch from 25kHz to 8.33kHz channel-spacing in VHF voicecommunications is designed to increase the number of available frequencies. This willenable operational improvements such as airspace restructurisation to be supported.

1.1.2 The mandatory carriage of 8.33 kHz-compatible radio equipment came into effect aboveflight level 245 for the whole of the ICAO EUR Region on the 7th October 1999. SevenEuropean States - Austria, Belgium, France, Germany, Luxembourg, the Netherlands andSwitzerland enforced the mandatory carriage, whilst the remaining States publishedexemptions.

1.1.3 The States participating in the 8.33 kHz Horizontal Expansion are: Bosnia & Herzegovina,Croatia, Czech Republic, Denmark, Estonia, Finland, The former Yugoslav Republic ofMacedonia (FYROM), Hungary, Ireland, Italy, Latvia, Lithuania, Norway, Poland, Portugal,Slovak Republic, Romania, Slovenia, Spain, Sweden, United Kingdom and FR Yugoslavia.The majority of these States will remove their 8.33 exemptions from 31 OCT 2002.

1.2 BACKGROUND

1.2.1 Based on the relevant conclusions of the Special EUR Regional Air Navigation Meeting(EUR RAN, Vienna, September 1994) and the Special Communications/OperationsDivisional Meeting (SP COM/OPS/95, Montreal, March-April 1995) the “Plan for the 8.33 kHzChannel Spacing Implementation in Europe” (Edition 2.0) was developed byEUROCONTROL.

1.2.2 This Plan was fully endorsed by the 38th Meeting of the European Air Navigation PlanningGroup (EANPG) in November 1996.

1.3 DECISIONS

1.3.1 The carriage and operation of 8.33 kHz channel spacing capable radio communicationequipment became mandatory in the ICAO EUR Region on 7th October 1999 for aircraftoperating above FL 245 generally and for aircraft operating above FL195 over France.

1.3.2 France has temporarily waived the requirement for the carriage of 8.33 kHz capable radiosfor aircraft operating with a requested cruising level between FL195 and FL245.



1.3.3 Certain consequential changes to the information to be contained in the flight plan of aircraftoperated in the ICAO EUR Region above FL 245 have been applicable since 1st October1998.

1.4 THE 8.33 PROGRAMME AND THE EUROPEAN CONVERGENCE ANDIMPLEMENTATION PLAN (ECIP)

1.4.1 The European Convergence and Implementation Plan (ECIP) is a common planning andimplementation tool for improving European ATM. It takes as its foundation the need to setand realise, specific quantifiable and measurable ATM Performance Targets for the ECACStates in the key ATM performance areas.

1.4.2 The first part of this programme “Implement 8.33 kHz VHF frequency channel spacing inEurope”, covered by the abbreviated ECIP Objective name COM01, has been achieved 07October 1999.

1.4.3 The second part of the programme, named by the ECIP Objective COM02, relates to thehorizontal expansion of the use of 8.33 kHz VHF frequency channels.

• general background information;• information on flight planning and communications procedures;• information on frequency management issues;• information on equipment standards and retrofit;• safety information and actions;• official reference documents and contacts;• regulatory material that can be used as specimen;• a general planning.

2.4 ICAO AND OTHER DOCUMENTATION

2.4.1 Users are reminded to consult also the relevant aeronautical documentation (in particularICAO Doc 7030 Regional Supplementary Procedures, State AIP and AIC issued on thissubject, the IFPS Users Manual and the CFMU Handbook) for more specific orsupplementary information.

2.4.2 Documentation on the European Convergence and Implementation Plan (ECIP) is availableat EUROCONTROL



3. GENERAL

3.1 MANDATORY CARRIAGE AREA

3.1.1 The carriage of 8.33 kHz channel spacing capable radio equipment has been mandatorysince the 7th October 1999, for aircraft operating in the ICAO EUR Region above FL 245, onthe understanding that an individual State may grant exemption(s) within its area ofresponsibility (refer to Chapter 7 for details on exemptions).

3.2 INITIAL 8.33 STATES

3.2.1 The seven States that initially implemented 8.33 kHz channel-spacing operations are:Austria, Belgium, France, Germany, Luxembourg, Netherlands and Switzerland (hereafterknown as Initial 8.33 States).

3.3 8.33 HORIZONTAL EXPANSION STATES (8.33 HEX STATES)

3.3.1 The States participating in the 8.33 kHz Horizontal Expansion are: Bosnia & Herzegovina,Croatia, Czech Republic, Denmark, Estonia, Finland, FYROM, Hungary, Ireland, Italy,Latvia, Lithuania, Norway, Poland, Portugal, Slovak Republic, Romania, Slovenia, Spain,Sweden, United Kingdom and FR Yugoslavia (hereafter known as 8.33 HEX States). Themajority of these States will remove their 8.33 exemptions from the 31st OCT 2002.

3.3.2 The Baltic States (Estonia, Latvia, Lithuania) will implement 8.33 kHz channel spacingoperations and remove published exemptions later.

3.4 OTHER STATES

3.4.1 The States within the 8.33 kHz radio equipment Mandatory Carriage Area that are notcurrently going to implement 8.33 kHz channel-spacing operations in their airspace, mayneed to take action in the fields of Operations (re-routing non-equipped aircraft), FrequencyManagement (shifting frequencies when so required) and Retrofit (fleet compliance withrequirement applicable in the whole of the ICAO EUR Region). Those States are hereafterknown as Other States.

3.4.2 Other States in the EUR Region may plan to implement 8.33 kHz channel spacing operationabove FL245 at a later stage. Such States should refer to Chapter 14 for information on theprocess that they should follow.

3.5 IMPORTANT REMARKS



3.5.1 Except where exemption(s) apply and as specified by the terms of the exemption(s), only8.33 kHz equipped aircraft are allowed to operate in the ICAO EUR Region above FL 245since the 7th of October 1999.

3.5.2 Where an 8.33 kHz channel has been promulgated, no alternative 25 kHz frequency will bepublished.

3.5.3 The only 8.33 non-equipped aircraft permitted to fly in 8.33 airspace are State Aircraft withUHF radio equipment where UHF coverage is provided or special procedures areimplemented.

3.5.4 Aircraft concerned must be equipped with at least two sets of 8.33 kHz capable radioequipment to meet the relevant provisions of JAR/OPS of 1 April 1995 on Commercial AirTransport Aviation.

3.5.5 If you transmit using 25 kHz in an 8.33 kHz channel spacing environment, you will either notbe heard, block out others on adjacent channels, or both, and all this in an unpredictableway, due to the nature of the 8.33 kHz channel spacing and the equipment used.

3.5.6 The inclusion of all equipment and capability information in an RPL is now mandatoryaccording to Amendment 200/2000 to the European Regional Supplementary ProceduresICAO Doc 7030/4.

3.6 STATE AIRCRAFT

3.6.1 States implementing the 8.33 kHz channel spacing are expected to make appropriatearrangements to cater for the requirements of State aircraft operating as General Air Traffic(GAT) and not able to communicate on the 8.33 kHz spaced channels. For the definition ofState Aircraft, please refer to Annex F, Handling State Aircraft.

3.6.2 Furthermore, ICAO has been requested to encourage European States to maintain and/or toachieve sufficient UHF coverage in the areas where the new channel spacing is introducedand to adapt their procedures accordingly.

3.7 AMENDMENTS TO RELEVANT ICAO DOCUMENTATION

These amendments include:



3.7.1 The insertion in the Chapter 4.0 ”Air-Ground Communications and In-Flight Reporting” of theICAO SUPPS Doc. 7030/4-EUR, Part I EUR/RAC. This specifies the mandatory carriagerequirements of 8.33 kHz channel spacing capable radio equipment, the area of operationsand exemptions. Also mentioned, that when UHF ground infrastructure permits, non-equipped State aircraft will be allowed to operate in the airspace designated for 8.33 kHzchannel spacing operations. This chapter mentions the Phraseology related to 8.33 kHzchannel spacing.

3.7.2 The insertion of a new sub-paragraph a) to PC 6.1 of Part X-COM of the European AirNavigation Plan, specifying that, when frequencies are assigned to VHF AMS facilities,geographical separation criteria and 8.33 kHz interleaving between channels is to be takeninto account for the area where this channel spacing is applicable.

3.7.3 The insertion of a new sentence in MA 6.4 of part X-COM of the European Air NavigationPlan, ICAO Doc. 7754/23, specifying measures, similar to those already undertaken byStates not yet having a requirement to implement 25 kHz channel spacing, to be undertakenby those States which do not yet have a requirement to implement 8.33 kHz channel spacingoperations but which are located within air-to-air interference range to another State whichdoes employ that channel spacing.

3.7.4 The inclusion in the Chapter 3.0 “Flight Plans” of the ICAO SUPPS Doc. 7030/4-EUR Part IEUR/RAC, of the relevant flight plan completion procedures. These specify the usage of adedicated letter (‘Y’) and indicator (‘STS/EXM833’) for insertion in fields 10 and 18respectively, so that the relevant flight plan can be accepted and not rejected by the IFPS.

3.7.5 The amendment 200/2000 to Chapter 3.0 “Flight Plans” of the ICAO SUPPS Doc. 7030/4-EUR Part I EUR/RAC (para. 3.1.1.2), making mandatory the inclusion of all equipment andcapability information in Item Q of an RPL.

3.8 AERONAUTICAL INFORMATION CIRCULAR (AIC) OF STATES

3.8.1 An Aeronautical Information Circular (AIC) will be published by the States concerned for theearly notification of users. It will include, amongst other things, the amendments to theEuropean Regional Supplementary Procedures concerning the completion of relevant flightplans. (Refer to Annex C for specimen)

3.9 AERONAUTICAL INFORMATION PUBLICATION (AIP) OF STATES

3.9.1 The recommended text for the AIP specimen is reflected in Annex B.

3.10 PROGRAMME TIMESCALE

3.10.1 Planning information is provided in Annex H.



4. 8.33 FLIGHT PLANNING

4.1 FLIGHT PLANNING PROCEDURES

4.1.1 Do not plan your flight in the ICAO EUR Region above FL 245, if the aircraft is not equippedwith 8.33 kHz capable radios, unless your flight is subject to exemption (Chapter 7 of thisUser Guide refers).

4.2 FPL

4.2.1 Flight Planning – FPL

4.2.2 If your aircraft is equipped with 8.33 kHz capable radios: insert the letter ‘Y’ in Field 10 of thefiled flight plan, regardless of the requested flight level.

4.2.3 If your aircraft is NOT equipped with 8.33 kHz capable radios but you are a State aircraftequipped with UHF: insert the letter M in field 8, the letter U in field 10 and the indicator‘STS/EXM833’ in Field 18 of the filed flight plan.

4.2.4 If your aircraft is NOT equipped with 8.33 kHz capable radios but your flight is exemptedfrom the carriage requirement: insert the indicator ‘STS/EXM833’ in Field 18 of the filed flightplan.

4.2.5 If you change from an 8.33-equipped aircraft to a non-8.33 equipped aircraft: follow theapplicable filed flight plan modification procedure, including in the modification message(CHG) or new flight plan, as appropriate, a Field 10 without the letter ‘Y’. Do not forget tomodify also your requested cruising level(s) if the original level(s) was (were) higher than FL245

4.2.6 If the status of your flight changes from non-exempted to exempted follow the applicable filedflight plan modification procedure, for a Field 18 modification, as given in the IFPS UsersManual.

4.2.7 If the status of your flight changes from exempted to non-exempted: follow the applicablefiled flight plan modification procedure, for a Field 18 modification, as given in the IFPS UserManual. Do not forget to modify also your requested cruising level(s) if the original level(s)was (were) higher than FL 245.

Note: Medical and Hospital Flights are covered in paragraph 5.5.

4.3 RPL

4.3.1 Flight Planning RPL

8.33 EQUIPPED ?

Insert “Y” in Item QExempt from Carriage ?

No Yes

Do not insert “Y”, BUT DOInsert “STS/EXM833” in Item Q

(Re-)plan your flight below FL245

No Yes



4.3.2 RPLs with a requested cruising level above FL245, must be operated by an 8.33 equippedaircraft, or the flight must be planned in accordance with published exemptions.

4.3.3 In RPL of flights that are operated with an 8.33 equipped aircraft, include the letter ‘Y’ in ItemQ within the EQPT/ element.

4.3.4 In RPL of flights that are subject to exemption, include in Item Q the indicator ‘STS/EXM833’.

4.3.5 For a flight planned to operate in the ICAO EUR Region above FL 245, if there is no letter ‘Y’in the EQPT/ element and no ‘STS/EXM833’ in Item Q, the RPL will fail the processing.

4.3.6 If on the day of operation there is a change in the 8.33 capability status or exemption statusof the flight, use the RPL modification-for-the-day procedure, including in the modificationmessage (CHG-to be sent not earlier than 20 hours prior to EOBT) or the new flight plan, asappropriate, a Field 10 without the letter ‘Y’. Do not forget to modify also your requestedcruising level(s), if required.

4.3.7 In all cases, if a Modification Message (CHG) would result in changes to the filed orrepetitive flight plan which would constitute a reason for the rejection of that flight plan, theModification Message will be rejected by the IFPS. It is therefore essential to indicate ALLthe modifications that are required in order to reflect a valid flight plan.

4.3.8 Example: A flight plan has been filed for an equipped aircraft above FL245. It is then realisedthat the aircraft will not be equipped. It is not sufficient to send a CHG simply indicating achange to the equipment without also indicating the necessary change to the requested flightlevel and/or route.

4.4 RPL SUBMISSION

4.4.1 NOTE: RPLs listings submitted after the 4th October 2001 are no longer assumed to be8.33kHz radio equipped.

4.4.2 All information which is relevant to 8.33 processing must be provided in the RPLs submittedto CFMU in the form of a NLST (New List) or RLST (Revised List) from 4th October 2001onwards.

4.4.3 8.33 kHz equipped aircraft shall include under the EQPT/ element in Item Q of the RPL theletter ‘Y’ together with ALL other equipment and capability information. The data providedshall be the complete information in Field 10 type of format e.g. EQPT/SHRYX/C (see alsoIFPS Users Manual). Each FPL generated from an RPL will contain in Field 10 theequipment information as provided after the EQPT/ element in the corresponding RPL.

4.4.4 In appropriate cases, the exemption indicator (STS/EXM833) shall be provided in Item Q ofthe RPL. Each FPL generated from the RPL will contain the exemption indicator in Field 18.



4.4.5 An RPL for a flight which is above FL245 within the IFPZ and which does NOT contain eitherthe exemption indicator or the letter ‘Y’ within the EQPT/ element will fail RPL processing.

4.5 IFPS PROCEDURES

4.6 ‘8.33 NON-COMPLIANCE’ CHECK

4.6.1 IFPS will deem a flight plan to be ‘8.33 non-compliant’ when:

I. at least a part of the flight is inside the IFPS Zone and above FL 245, but theaircraft is not equipped with 8.33 radios (no ‘Y’ in Field 10) and the flight is notplanned in accordance with published exemptions (no ‘STS/EXM833’ in Field 18)

II. the flight penetrates an 8.33 sector and:

• EITHER : the aircraft is not equipped with 8.33 radios (no ‘Y’ in Field 10) ;• OR : the aircraft is a State aircraft, but is not equipped with either 8.33

radios or UHF radios (no ‘Y’ or ‘U’ in Field 10);• OR : the aircraft is a non-8.33 equipped State aircraft (no ‘Y’ in Field 10),

which is equipped with UHF radios (‘U’ in Field 10) but the sectorconcerned does not allow the use of handling of UHF equipped aircraft.

4.7 IFPS 8.33 PROCESSING

4.7.1 Flight plans which are deemed to be ‘non-8.33 compliant’ will fail IFPS processing. Theresultant action by the IFPS depends upon the aerodrome of departure as follows:

4.7.2 Aerodrome of departure is inside the IFPS Zone:

=>FPL rejected=>REJ message returned to the FPL originator and/or aircraft operator

e.g.:-TITLE REJ -MSGTYP IFPL -ORIGINDT 9910150024-BEGIN -ADDR-FAC SVMIZPZX-END -ADDR-ERROR PROF: FLIGHT PLAN DOES NOT COMPLY WITH 8.33kHz CARRIAGEREQUIREMENTS-OLDMSG (FPL-VIA745-IS-DC10/H-SDHIX/C-LEMD0150-N0499F209 CCS UG7 ESP/N0479F350 DCT KOMUT/N0474F330 DCT 38N020W36N030W 33N040W27N050W 18N060W/M082F330 DCT PPR UA550 TOROP DCT DARPA DCT-SVMI0727 SVTP-EET/LECM0035 LPPC0115 020W0241 030W0350 LPPO0445 050W0536 KZNY0602TTZP0649 REG/YV138C SEL/CFLM)



4.7.3 Aerodrome of departure is outside the IFPS Zone:

=>FPL marked as non-compliant and distributed to the ATC Units concerned,with IFP/NON833 added in field 18,

e.g.:(FPL-VIA744-IS-DC10/H-SDHIX/C-SVMI0150-N0499F209 DCT DARPA DCT TOROP UA550 PPR DCT 18N060W/M082F330 27N050W 33N040W 36N030W 38N020W DCT KOMUT/N0474F330 DCT ESP N0479F350 UG7 CCS TLD1DA-LEMD0727 LEBL LPPR-EET/TTZP0035 KZNY0115 050W0241 LPPO0350 030W0445 020W0536 LPPC0602 LECM0649 REG/YV138C SEL/CFLM IFP/NON833)

=> ACK message returned to the FPL originator and/or aircraft operatorincluding a warning indication

DOF/991012)

4.8 IFPS PROCESSING FROM 00.00 UTC ON 18 APRIL 2002 UNTIL 23.59UTC ON 30TH OCTOBER 2002

4.8.1 During this period, IFPS will issue warning messages for exempted non-8.33 equippedaircraft filing above FL245 in the 8.33 HEX States. Flight plans for such flights will NOT failIFPS processing if they are properly filed based on the exemptions applicable up to 31st

October 2002.

4.8.2 A flight plan for an exempted flight of a non-8.33 equipped aircraft, filing to operate aboveFL245 in the 8.33 HEX States, will continue to be processed and will be distributed by IFPSas usual. However, the ACK message that is returned to the originator of the flight planand/or to the aircraft operator will contain a warning indication.



e.g.:-TITLE ACK -MSGTYP IFPL -ORIGINDT 0207310502-BEGIN ADDR -FAC LIRFAZAW -END ADDR-COMMENT FLIGHT PLAN MAY BE REJECTED IF FILED AFTER 30/10/2002 DUE TO 8.33KHZ RADIO REQUIRMENTS-IFPLID BB24836140-MSGTXT (FPL-AZA8953-IS-PAY3/L-SD/C-LIPY1100-N0277F250 LEONN UA15 BOL UZ800 TAQ UZ801 VALMA UG23 ALG-LIEA0105 LIRA LIEE-EET/LIRR0002 STS/EXM833 DOF/020731 ORGN/LIRFAZAW)

4.9 8.33 STATUS UNKNOWN

4.9.1 The IFPS functionality includes the processing of certain messages which concern anaircraft already in flight. As the aircraft is already flying, IFPS does not reject such messages.The following are the messages and scenarios concerned:

• ATC Flight Plan Proposal Message (AFP) - created by an ATC unit and sent to IFPSwhen the ATC unit has received estimate information concerning an aircraft for which ithad no flight plan;

• Flight Notification Message (FNM) & Message from Shanwick (MFS) - co-ordinationmessages concerning eastbound North Atlantic flights;

• Air Filed Flight Plans (AFIL) - flight plan filed with an ATS Unit while the aircraft is in theair.

The ‘downstream’ ATC Units will receive an ATC Flight Plan (APL) message or an ATCFlight Plan Change (ACH) message, as appropriate, and in case of an air filed flight plan, aFPL message.

4.9.2 If the flight plan for the concerned flight does not already exist in IFPS and the informationreceived by IFPS does not show either the carriage of 8.33 compatible radio equipment (‘Y’in Field 10) or an exemption (STS/EXM833 in Field 18), then IFPS will insert a warningindicator in Field 18 of the output message as follows:

IFP/833UNKNOWN

Note: Since in case of an ACH message a flight plan for the concerned flight does alreadyexist in IFPS and it has already been distributed to the receiving ATC unit, it follows thereforethat the warning indicator above may only be found within APL and air filed FPL messages.



4.10 RE-ROUTING

4.10.1 The aircraft operator is always responsible for ensuring that the information provided in theflight plan (i.e. 8.33 equipage information or the presence of the exemption indicator) isconsistent with the aircraft to be used, the route to be flown and the requested cruisinglevels.

4.10.2 Re-routing proposals (RRP Messages) received from the CFMU Tactical System will NOTtake into consideration 8.33 exemption requirements. However if an alternative route, whichwould render the aircraft ‘8.33 non-compliant’, is accepted by the Aircraft Operator, the re-filed flight plan will fail IFPS processing.

4.11 OCCASIONS WHEN IFPS WILL NOT BE ABLE TO PROVIDE ATC WITHPRIOR WARNING OF NON-EQUIPPED AIRCRAFT PLANNED TO ENTERTHE AIRSPACE OF MANDATORY CARRIAGE

4.11.1 IFPS will not add a warning indicator to a flight plan which it does not distribute. This meansthat a warning will only be added to flight plans addressed to units outside the IFPZ, if theflight plan has been submitted to IFPS for group addressing. Therefore, if your sector isoutside the IFPZ and you receive a flight plan not distributed by IFPS, you will have noadditional indicator (other than the information available in Fields 10 and 18 of the FPL), thata particular aircraft is not equipped and extra care must be taken when transferring aircraftsto sectors within the IFPS Zone.

5. OPERATIONAL ASPECTS

5.1 GENERAL

5.1.1 The pilot is ultimately responsible for ensuring that the radio communication equipmentappropriate for the flight to be conducted is available and operational on board the aircraft.

5.1.2 To ensure successful operation and safe conduct of air/ground communication within the8.33 environment, it is essential that ATC units with sectors operating in the 8.33 channelspacing, and the ATC units adjacent to them co-operate effectively.

5.1.3 Tactical re-routing and/or descent below 8.33 sectors of non-8.33 equipped aircraft are notnecessarily an option in a complex and busy airspace. Unplanned diversion may be the onlyalternative, particularly where the route network below FL245 is different to that at higherlevels.

5.1.4 Providing that no exemptions are applicable, ATC units controlling adjacent or subjacentairspace, must ensure that aircraft not properly equipped do not enter airspace in which thecarriage and operation of 8.33 kHz capable radio communication equipment is mandatory.Within and between ATC units, agreements must be made to meet this requirement.Appropriate arrangements must also be made for the handling of State aircraft. (A specimenLetter of Agreement is provided at Annex E)

5.1.5 As previously described in this User Guide (Chapters 4 refers), the IFPS will provide adegree of protection against improperly equipped aircraft planned to operate above FL 245in the EUR Region by rejecting their flight plans if the aerodrome of departure is within theIFPS Zone (hereafter IFPZ), or by inserting a warning in the flight plan if the aerodrome ofdeparture is outside the IFPS Zone.

5.1.6 As previously described in this User Guide (Chapter 4 refers), for a period of time in advanceof 31 October 2002, the IFPS will issue warning messages for exempted non-8.33 equippedaircraft filing above FL245 in the 8.33 HEX States.

5.2 FLIGHT PLANNING PROCEDURES FOR AIRCRAFTS WITH REQUESTEDCRUISING LEVEL BELOW FL245

5.2.1 Aircraft normally capable of operating above FL245, but planning to fly below these levels,shall, nevertheless, insert the appropriate indicator.

5.2.2 Irrespective of the RFL, it is essential that field 10 of the FPL accurately reflects the 8.33equipage of the aircraft, and therefore the letter ‘Y’ shall be inserted in field 10 of the flightplan for aircraft equipped with 8.33 kHz capable radio equipment, and omitted for non-8.33equipped aircraft.



5.3 COMMUNICATIONS PROCEDURES

5.3.1 The communication procedures shall be in accordance with Volume II of Annex 10, Chapter5, and flight crew, ATS personnel and other ground personnel shall be thoroughly familiarwith the radiotelephony procedures contained therein.

5.3.2 The radiotelephony transmission of 8.33 and 25 kHz spaced channels is described in Annex10, Volume II, Chapter 5, para 5.2.1.6.3.4.3 and para 5.2.1.6.3.4.4

5.3.3 The phraseology related to 8.33 kHz channel spacing is published in ICAO SUPPS – Doc7030/4, EUR/RAC-6, Table 1. (See Annex I to 8.33 User Guide)

5.4 USE OF UHF BY STATE AIRCRAFT

5.4.1 States implementing the 8.33 kHz channel spacing are expected to maintain and/or establishsufficient UHF coverage and to adapt their procedures as necessary, in order for air trafficservices to be able to provide service to State aircraft equipped with UHF but without 8.33kHz capability. It is essential that relevant information be published in the national AIP.

5.4.2 ATS personnel are expected to ascertain on first contact the communications capabilities ofState aircraft planned to operate in the airspace of Mandatory Carriage.

5.4.3 Where the ground infrastructure permits, State aircraft without 8.33 capability but UHFequipped, shall be allowed to enter 8.33 airspace provided that UHF coverage is in place orif not, that specific procedures are available.

5.4.4 If a State aircraft has neither UHF nor 8.33 capability it must be denied entry into airspace ofmandatory carriage and must be (re)cleared outside such airspace.

5.4.5 While UHF is expected to provide an alternative means of communication for State aircraft atleast in some parts of the ICAO EUR Region, it is essential that State transport aircraft whichare frequent users of 8.33 kHz airspace be fitted with 8.33 capability.

5.4.6 UHF frequencies are managed by NATO according to NATO Frequency Managementcriteria, based on States needs. NATO co-ordination is applicable to both Members of NATOand members of the Euro-Atlantic Partnership Council.

5.5 MEDICAL FLIGHTS AND FLIGHTS ON SEARCH AND RESCUE MISSIONS(HOSP AND SAR ONLY)



5.5.1 Medical flights specifically declared by the medical authorities, and aircraft engaged insearch and rescue missions1, are not exempt from the 8.33 kHz mandatory carriagerequirement. However, due to the frequently urgent nature of these flights, they are subjectto a special IFPS processing.

5.5.2 To ensure the correct processing of the flight plan, HOSP and SAR flights are required toinsert STS/HOSP and STS/SAR, as appropriate, in field 18 of the flight plan. Flight planscontaining either of these indicators will not be rejected by IFPS, even if there is no ‘Y’ inField 10 to indicate 8.33 equipage, and the aircraft is planned to enter airspace where noexemption is applicable (except for UHF equipped State aircraft).

5.5.3 Nevertheless, you should insert the letter ‘Y’ in field 10, if the aircraft is equipped with 8.33kHz capable radios, because this will prevent IFPS including a warning in the flight plan itdistributes, and will avoid unnecessary questions from ATC.

5.5.4 The above measures have been implemented to ensure that the processing of flight plans ofSAR and HOSP status flights, which are often composed and filed with considerable urgencyand hence are prone to unintentional errors, is not delayed unnecessarily.

5.5.5 The communication capability of HOSP or SAR flights which have failed to indicate them,and which are planned to operate in airspace where the carriage and operation of 8.33 kHzradios is mandatory, must be verified by ATC as soon as possible. At the latest, ATC in the25kHz sector immediately before an 8.33kHz sector should verify, on first contact, the 8.33status of such aircraft.

5.5.6 It is likely that a limited number of HOSP/SAR flights may also be State aircraft equippedwith UHF. In this case, the flight would qualify for the exemption applicable to State aircraft,where UHF is available, and operators may insert ‘STS/EXM833’ in Field 18, ‘U’ in field 10and ‘M’ in field 8. The aircraft will then be handled as a UHF equipped State aircraft.

5.5.7 It is important to note that HOSP and SAR flights are not exempt from the 8.33 kHz radiomandatory carriage requirement, and a non-8.33 and non-UHF equipped HOSP or SARflight will be handled clear of airspace where no exemption applies.

5.6 WHAT HAPPENS IF ?

5.6.1 Your departure aerodrome is within the IFPS Zone, your aircraft is not equipped with8.33 kHz radios and your flight is not planned in accordance with publishedexemptions (no ‘Y’ in Field 10 and no ‘STS/EXM833’ in Field 18), and you file arequested cruising level anywhere in the IFPS Zone above FL 245? (Annex G refers)

Since aircraft not equipped with 8.33 kHz capable radio, and not exempted from thisrequirement, are not permitted to fly above FL 245, your flight plan will be rejected by theIFPS, with a REJ message containing the reason(s) for the rejection. Re-file with therequested cruising level(s) adjusted accordingly.

1 HOSP and SAR as defined in IFPS Users Manual



5.6.2 Your departure aerodrome is within the IFPS Zone, your aircraft is not equipped with8.33 kHz radios but your flight is planned in accordance with published exemptions(no ‘Y’ in Field 10 but ‘STS/EXM833’ shown in Field 18), and you file a requestedcruising level anywhere in the IFPS Zone above FL 245

Your flight plan will be processed as usual and air traffic services will assume that youroperation will be within the terms of the exemption. As an example, your exemption mighthave been granted on the basis of your destination aerodrome and/or a planned route. Anychange to one or both of those elements of your flight plan might make the exemptioninvalid and will be the subject of individual consideration by ATC, based among otherthings on the need to maintain continuous communication. You might have to descend orselect another aerodrome of landing.

5.6.3 Your departure aerodrome is outside the IFPS Zone, your aircraft is not equipped with8.33 kHz radios and your flight is not planned in accordance with publishedexemptions (no ‘Y’ in Field 10 and no ‘STS/EXM833’ in Field 18), and you file arequested cruising level anywhere in the IFPS Zone above FL 245 (Annex G refers)

Since aircraft not equipped with 8.33 kHz capable radio and not exempted from thisrequirement are not permitted to fly above FL 245, and it is not practicable to reject yourflight plan, it will be processed by the IFPS, but it will be marked by an appropriate textwhich can be processed by local air traffic control systems and which indicates the need forspecial handling. The acknowledgement message (ACK) sent by the IFPS to the flight planoriginator and/or aircraft operator will also contain such a warning. Depending on whereyou are entering the IFPS Zone and the local arrangements between the air traffic servicesunits along your route of flight, appropriate measures will be taken in good time to ensurethe safe conduct of your flight. Keep in mind however, the possibility that you will beinstructed to descend below FL 245 for a considerable portion of your flight to yourdestination. Such situations will almost always result in serious operational penalties.

The acknowledgement message (ACK) sent by the IFPS to the flight plan originator and/oraircraft operator will also contain the following warning:

“Comment This flight plan does not comply with 8.33 kHz radio requirements”

An operator, and/or flight plan originator, on receipt of such a warning from IFPS shouldcheck whether or not the aircraft is fitted with an 8.33kHz radio, and

A. if the aircraft is equipped, a CHG message should be sent indicating a modificationto Field 10 of the flight plan to include the letter ‘Y’e.g. (CHG-ABC123-KJFK-EDDF-10/SRXY/C)

B. if the aircraft is not equipped then:

1.if not yet airborne, replan the flight:• to remain clear of the airspace of mandatory carriage (EUR Region

above FL245), or• in accordance with published exemptions to 8.33 mandatory

carriage

2. if already airborne, ensure that the pilot-in-command of the aircraft is notified thathis aircraft will probably be diverted, re-routed or descended to remain clear of the8.33 mandatory carriage area.



5.6.4 Your departure aerodrome is outside the IFPS Zone, your aircraft is not equipped with8.33 kHz radios but your flight is planned in accordance with published exemptions(no ‘Y’ in Field 10 but ‘STS/EXM833’ shown in Field 18), and you file a requestedcruising level anywhere in the IFPS Zone above FL 245?

Your flight plan will be processed as usual and air traffic services will assume that youroperation will be within the terms of the exemption. As an example, your exemption mighthave been granted on the basis of your destination aerodrome and/or a planned route. Anychange to one or both of those elements of your flight plan might make the exemptioninvalid and will be the subject of individual consideration by ATC, based among otherthings on the need to maintain continuous communications possible. You might have todescend or select another aerodrome of landing.

5.6.5 You enter ‘Y’ in Field 10 of your flight plan but you have no 8.33 kHz radios on boardand you file a requested cruising level anywhere in the IFPS Zone above FL 245?

Your flight plan will be processed as usual. However, at some point along your route youwill encounter an ATC sector using an 8.33 kHz channel. Due to the nature of this channelspacing and the equipment used to communicate on it, you will either not be heard, blockout others on adjacent channels or both and all this in an unpredictable way. Any suchmisconduct is a serious infringement, a threat to your safety and will be dealt withaccordingly.

5.6.6 You enter ‘STS/EXM833’ in Field 18 of your flight plan, you have no 8.33 kHz radios onboard, you file a requested cruising level anywhere in the IFPS Zone above FL 245 andyour planned flight is not in accordance with published exemption(s)?

IFPS will check your flight plan against environment data provided by States. If your pointof departure is within the IFPZ your flight plan will be rejected and you will need to refile inaccordance with published exemptions. If your point of departure is outside the IFPZ, yourflight plan will be processed but marked by an appropriate text that can be processed bylocal air traffic control systems and which indicates the need for special handling. Theacknowledgement message (ACK) sent by the IFPS to the flight plan originator and/oraircraft operator will also contain a warning. Depending on where you are entering theIFPS Zone and the local arrangements between the air traffic services units along yourroute of flight, appropriate measures will be taken in good time to ensure the safe conductof your flight. Keep in mind however, the possibility that you will be instructed to descendbelow FL 245 for a considerable portion of your flight to your destination. Such situationswill almost always result in serious operational penalties.

5.6.7 You file a flight plan without ‘Y’ in Field 10 or ‘STS/EXM833’ in Field 18, with arequested cruising level below FL 245 generally in the IFPS Zone, and later send amodification message for the same flight (i.e. a aircraft not exempted and also without8.33 kHz capable radios), changing the cruising level to above FL 245 generally in theIFPS Zone?

You should never do this. However, if you do, the modification message will be rejected bythe IFPS.



In all cases, if a Modification Message (CHG) would result in changes to the filed orrepetitive flight plan which would constitute a reason for the rejection of that flight plan, theModification Message will be rejected by the IFPS. It is therefore essential to indicate ALLthe modifications that are required in order to reflect a valid flight plan.

e.g. A flight plan has been filed for an equipped aircraft above FL245. It is then realisedthat the aircraft will not be equipped. It is not sufficient to send a CHG simply indicating achange to the equipment without also indicating the necessary change to the requestedflight level and/or route.

5.6.8 You are on a SAR mission or a HOSPITAL flight and this is shown in Field 18 of yourflight plan, you file a requested cruising level anywhere in the IFPS Zone above FL245, your aircraft is not equipped with 8.33 capable radio equipment or you are a Stateaircraft not equipped with UHF?

Your flight plan will be processed by the IFPS, but it will be marked by an appropriate textwhich can be processed by local air traffic control systems and which indicates the need forspecial handling. Depending on the local arrangements between the air traffic servicesunits along your route of aircraft, appropriate measures will be taken to ensure the safeconduct of your flight but you must expect to be re-routed outside of the airspace ofmandatory carriage.

5.6.9 You are on a SAR mission or a HOSPITAL flight and this is shown in Field 18 of yourflight plan, you file a requested cruising level anywhere in the IFPS Zone above FL245, your aircraft is equipped with 8.33 radio capable equipment and you forget toinsert the letter “Y” in Field 10 or you are a State aircraft equipped with UHF and youforget to insert “STS/EXM833” in Field 18?

Your flight plan will be processed by the IFPS, but it will be marked by an appropriate textwhich can be processed by local air traffic control systems and which indicates the need forspecial handling. Depending on the local arrangements between the air traffic servicesunits along your route of aircraft, appropriate measures will be taken to ensure the safeconduct of your flight.

5.6.10 You are a State aircraft, your aircraft is not equipped with 8.33 kHz capable radios butyou are able to communicate on UHF and have entered ‘STS/EXM833’ in Field 18 ofyour flight plan and you file a requested cruising level anywhere in the IFPS Zoneabove FL 245?

IFPS will check your flight plan for UHF equipage and against the exemption and UHFenvironment data provided by States. If your flight plan does not indicate UHF equipage(no ‘U’ in field 10), and/or the route flown is not in accordance with published exemptions,including full UHF coverage where no other exemption is published, your flight plan will berejected.

5.6.11 You need to conduct emergency radio traffic?

The emergency channel 121.5 MHz is not affected by the new channel spacing. Itsavailability and its use remain unchanged.



6. CO-ORDINATION

6.1 GENERAL

6.1.1 As stated in Paragraph 5.1.1, it is the pilot who is ultimately responsible for ensuring that theradio communication equipment appropriate to the flight to be conducted is fitted andoperational on board the aircraft.

6.1.2 Nevertheless, there will be an operational impact on ATC, particularly for sectors that acceptnon-8.33 equipped aircraft but are immediately adjacent to sectors where no exemption tothe 8.33 kHz mandatory carriage requirement is permitted.

6.1.3 It is essential that information regarding 8.33 status of relevant aircraft is displayed to ATC.This information is available from the flight plan. In particular, if an aircraft with anaerodrome of departure outside the IFPS Zone has failed to indicate in the flight plan that itis carrying radio equipment appropriate for the planned route, a warning will be added to theflight plan Message distributed by the IFPS. This warning indicates that the aircraft is not8.33 equipped, and that special care must be taken. It is essential that the information thatan aircraft is not 8.33 equipped (whether or not this information is distributed by IFPS), isdisplayed to ATC. This means that, as a minimum, Field 10 must be processed by the ACC.If possible, Field 18 should also be processed. State aircraft equipped with UHF need to beidentifiable, because these are the only non-8.33 equipped aircrafts permitted to enter an8.33 sector. Listed below are the agreed operational requirements for systems support to8.33 kHz operations:

A. ATC systems should indicate to controllers the relevant 8.33 equipage status of anaircraft.

Note that this can be achieved through the flight progress strip or through the radartrack/label. There is no requirement to indicate it on both.

B. For non-8.33 equipped State aircraft, ATC systems should indicate to controllerswhether or not the aircraft is UHF equipped.

Note that non-833 equipped State Aircraft are exempted only if UHF equipped.

C. The possibility to change the 8.33 equipage status should be provided tocontrollers.

This capability caters for flight plan errors.

D. System notification and co-ordination data should include the current 8.33equipage status of an aircraft, and, for not equipped State Aircraft, indicate whether ornot the aircraft is UHF equipped.

E. The Eurocontrol OLDI Standard (Released Edition 2.2) has been amended to includeindication of (inter alia) 8.33 and UHF equipment (as specified in field 10) as well as thecurrent capability and status of the equipment (equipped and available/ not equipped or notavailable/ unknown).



The capability and status field may be updated by ATS if the information in the flight plan isfound to be incorrect. Inclusion of Field 18 STS/ information is optional and subject tobilateral agreement of the States concerned.

6.2 ATC 8.33 PROCEDURES

6.2.1 If your sector is outside the Airspace of Mandatory Carriage:

6.2.1.1 If your sector is not adjacent to any sector within the Airspace of MandatoryCarriage, no additional action is required.

6.2.1.2 If your sector is adjacent to a sector which is within the Airspace of MandatoryCarriage, but which allows unconditional exemption to non-equipped aircrafts, noadditional action is required.

6.2.1.3 If your sector is adjacent to a sector which is within the Airspace of MandatoryCarriage, but allows exemption to specified non-equipped aircrafts, you must besure of the aircraft’s radio capability or compliance with the conditions forexemption before transfer of control to that sector. A non-equipped aircraft mustoperate in accordance with the specific conditions for exemption applicable withinthe next sector and if it does not, an alternative clearance must be co-ordinated.

6.2.1.4 If your sector is adjacent to a sector which is within the Airspace of MandatoryCarriage within which flight of non-equipped aircraft is not permitted (i.e. noexemptions are applicable except to UHF equipped State aircraft), you must besure of the aircraft’s 8.33 or UHF radio capability before transfer of control to thatsector, and if it is not appropriate, you must co-ordinate an alternative clearance

6.2.2 If your sector is within the Airspace of Mandatory Carriage, and no flight of non-equipped aircraft is permitted within your sector (You may or may not be operating afrequency within the 8.33 kHz spectrum).

6.2.2.1 You do not need to confirm the 8.33 or UHF capability of any aircraft within yourairspace. This will have been done by preceding sectors. All aircraft within yourairspace must be properly equipped. You need to be aware, however, that thereis a slight possibility of severe interference caused by aircraft which are notproperly equipped, communicating with another 8.33 sector using a 25 kHzfrequency.

6.2.3 If your sector is within the Airspace of Mandatory Carriage, but specified flights of non-equipped aircraft are permitted within your sector.

6.2.3.1 You should only receive aircrafts from adjacent sectors which are in accordancewith the carriage and exemption requirements of your sector.



6.2.3.2 If your sector is adjacent to a sector within the Airspace of Mandatory Carriagewhich allows exemption to specified non-equipped aircraft, you must be sure ofthe aircraft’s 8.33 or UHF radio capability or compliance with the conditions forexemption before transfer of control to that sector. A non-equipped aircraft mustoperate in accordance with the specific conditions for exemption applicable withinthe next sector and if it does not, an alternative clearance must be co-ordinated.

6.2.3.3 If your sector is adjacent to a sector within the Airspace of Mandatory Carriagewithin which flight of non-equipped aircraft is not permitted (i.e. no exemptionsare applicable apart from UHF equipped State aircraft), you must be sure of theaircraft’s 8.33 or UHF radio capability before transfer of control to that sector, andif it is not appropriate, you must co-ordinate an alternative clearance.



7. PRINCIPLES OF EXEMPTION

7.1 8.33 STATES (INITIAL AND HORIZONTAL EXPANSION)

7.1.1 Only 8.33 kHz equipped aircraft are allowed to operate in the ICAO EUR Region above FL245 since the 7th of October 1999.

7.1.2 The only 8.33 non-equipped aircraft permitted to fly in 8.33 airspace are State Aircraftwith UHF radio equipment where UHF coverage is provided or special procedures areimplemented.

7.2 OTHER STATES WITHIN ICAO EUR REGION

7.2.1 States in the Area of Mandatory Carriage may publish exemptions to the carriagerequirement within their area of responsibility. An exemption allows flight of non-8.33equipped aircraft within that portion of the airspace of Mandatory Carriage where theexemption applies.

7.2.2 The exemption indicator may only be added to flight plans if the entire flight is planned inaccordance with the published exemptions.

7.2.3 The aircraft operator is responsible for ensuring that in the FIR/UIR concerned by the flightplanned route of a non-8.33 equipped aircraft, exemptions are applicable. Otherwise theflight must be planned below FL245.

7.3 TYPES OF EXEMPTION

7.3.1 Exemptions may be granted by States within the Area of Mandatory Carriage, but which arenot actually implementing 8.33 kHz channel spacing. Such exemptions may be eitherunconditional or conditional.

• Unconditional: all flights of non-equipped aircraft are permitted.• Conditional: only clearly specified categories of flight are permitted.

Exemptions must be clearly specified so that there is no doubt whether a flight may or maynot proceed through the airspace concerned. Examples of conditional exemptions:

• Domestic flights;• Flights not entering specified portion(s) of the airspace.



7.3.2 Lists of exemptions granted by States within the Airspace of Mandatory Carriage will beavailable to aircraft operators for flight planning purposes in State AIP.

7.3.3 In order to insert STS/EXM833 in field 18 of your flight plan, the entire flight must be plannedin accordance with published exemptions. If within any FIR/UIR on the flight planned routeno exemption to non-equipped flight is applicable, then either:

• the “STS/EXM833” indicator is not to be inserted in the flight plan, and the flightmust be planned outside the Airspace of Mandatory Carriage, or

• the Flight must be planned to remain outside those parts of the Airspace ofMandatory Carriage within which no exemption applies, and in this case the“STS/EXM833” indicator may be added to the flight plan.

7.3.4 It is not recommended that States grant an unconditional exemption in view of the additionalworkload this may create in respect of the handling of such exempted aircraft.

7.3.5 Although State aircraft are required to insert “STS/EXM833” in their flight plan (refer toparagraph 7.2.3), this does not constitute an exemption as specified in this chapter. In thiscase, the “STS/EXM833” indicator is being used for data processing reasons only.

7.4 RECOMMENDATION FOR AIP TEXT ON EXEMPTIONS

7.4.1 It is recommended that the following text is inserted in section GEN 1.5 of the national AIP:

As required by ICAO SUPPS DOC 7030/4 EUR/RAC Chapter 4.0 ”Air-GroundCommunications and In-Flight Reporting”, the carriage and operation of 8.33 kHz channelspacing radio equipment is mandatory throughout the ICAO EUR Region (as of 7thOctober 1999) for flights operating above FL245.

Exemptions from mandatory carriage of 8.33 equipment are described in section ENR 1.8.

Non-equipped flights which are flight planned to enter any FIR/UIR in the EUR Regionwhere no exemption has been published, except for UHF equipped State aircraft, (refer tothe AIP of the State covering the FIR/UIR concerned) must flight plan to operate below FL245 throughout the entire EUR Region.

7.4.2 It is recommended that the following text is inserted in section ENR 1.8 of the national AIP ofother states (NON 833):

In accordance with Chapter 4.0 on ”Air-Ground Communications and In-Flight Reporting”,para. 4.1.2 of ICAO SUPPS Doc 7030/4 EUR/RAC, temporary permission is herebygranted for flight not equipped with 8.33 kHz channel spacing radio equipment to operate inthe xxx FIR/UIR on condition that:

a) Such flight is planned to remain clear of any FIR/UIR in the EUR Region where noexemption has been published except for UHF equipped State aircraft (refer tothe AIP of the State covering the FIR/UIR concerned);

ORb) Such flight is operated in accordance with exemptions published (refer to the AIP

of the State covering the FIR/UIR concerned);



ORc) (State list own, additional exemptions)

This temporary permission is subject to revision but is applicable at least until ddmmyyyy.

In respect of State aircraft no time limit applies.

7.4.3 It is recommended that the following text is inserted in section ENR 1.8 of the nationalAIP:

State aircraft which are infrequent users of the FIR/UIR (or sectors, as applicable) where8.33 kHz channel spacing is in actual use, are exempted from the above carriagerequirement, provided that they are able to communicate using UHF. They will beaccommodated on UHF frequencies (insert more details) and/or on VHF 25 in the sectorswhich are not converted to VHF 8.33 and/or according to the following procedures (insertmore details).

Note: Infrequent user is one defined as not exceeding about 30 hours flying time perairframe per year in the 8.33 airspace.

7.5 DETAILED EXPLANATION OF THE EXEMPTION TEXT

It is envisaged that the proposed text above (shown in italics) would be inserted in thenational AIP in the parts indicated, in a basically unchanged form to ensure that airspaceusers receive common, consistent and unambiguous information on the applicableexemptions in each State of the EUR Region.

7.5.1 Explanation of paragraph 7.4.1

• Although the requirement refers to the whole EUR Region, temporary exemption tooperate without 8.33 kHz capable equipment may be granted under specific conditions asdescribed in section ENR 1.8.

• It is envisaged that the exemptions will be granted in the form of a temporary permissionto operate in accordance with the conditions specified. The use of the words “temporarypermission” is meant to highlight the fact that the mandatory carriage requirement is notaffected as such.

• The requirement in the last sentence of paragraph 7.4.1 to flight plan non-8.33 equippedaircraft below FL 245 throughout the whole EUR Region is to avoid:

a) IFPS rejection of the flight plan.b) unnecessary increase of workload in congested areas, due to the requirement to

ensure that non-equipped aircraft remain clear of sectors where 8.33 kHz channelspacing is implemented.



This requirement should not prevent ATC from tactically allowing aircraft to climb ordescend once clear of FIR/UIR (or sectors, as applicable) where 8.33 kHz channel spacingis in actual use. However, operators of non-equipped aircraft should not rely on thispossibility.


Note that the exemptions described in paragraph 7.4.2 are of a temporary nature and maybe withdrawn after informing the airspace users.

The exemptions apply equally to State aircraft which will never enter an FIR/UIR (orsectors, as applicable) where 8.33 kHz channel spacing is in actual use.

In respect of FIR/UIR where 8.33 kHz channel spacing is being introduced, normally noexemptions will be published, except to UHF equipped State aircraft.

Therefore an aircraft can consider itself exempted if it does not enter any of these FIR/UIRor an aircraft can also consider itself exempted if it is planned to enter any one or more ofthose FIR/UIR in accordance with the specific exemptions if any, published in thecorresponding AIP.

With regard to c), it is envisaged that specific exemptions will be listed which are notcovered by points a) and b) and/or in the case of 8.33 States, the exemptions referred to inpoint b) will be listed here. It is also recommended to keep the number of exemptionsunder point c) to a minimum, in order to avoid an increase in ATC workload and safetyimplications.

Whilst all these exemptions apply in the FIR/UIR covered by a national AIP, points a) andb) are actually pointers to other national AIP which airspace users need to consult in orderto confirm the applicability of these exemptions to a particular aircraft.

Note again the temporary nature of these exemptions. It is envisaged that States enter adate commensurate with their expected need for future introduction of 8.33 channelspacing. Also take into account the need to conduct appropriate consultation with theairspace users. Even if no need for 8.33 spaced frequencies is foreseen, it isrecommended that States enter a hypothetical date.


This paragraph should clearly reflect the way the State is going to handle the exempted Stateaircraft. It should consider their handling in sectors that are not converted to 8.33 in particularduring the interim phase between the 31 Oct 2002 and the implementation of 8.33 channels.Where specific procedures such as handling by military controllers will be implemented, theAIP should clearly depict them.



8. FREQUENCY MANAGEMENT ASPECTS

8.1 GENERAL

8.1.1 For optimised VHF spectrum usage at national level, it is essential that good co-operationexists between the Aeronautical Frequency Management Department and Operational units(ACC, aerodromes etc.) of a State.

8.1.2 Proposals for changes to frequency assignment and operation (coverage, sector shape,height), should be submitted in advance by the Operational Unit to the FrequencyManagement Unit, in order to prevent frequency interference and ensure optimum use of thespectrum.

8.1.3 Airspace planners are reminded that changes to airspace structure and sectorisation mayrequire additional frequencies and that analysis should be carried out in the initial stages ofplanning. Consequently, frequency provision and planning should be done within a maximumtime frame of one year before implementation.

8.1.4 The ICAO EANPG FMG establishes the criteria for aeronautical frequency protection, as wellas the procedures for inter-State co-ordination of new frequencies/frequency changes inEurope.

8.1.5 The EATMP ARB provides support (assessment and prioritisation) to the FMG and theStates, by reviewing the new frequency requirements and frequency assignments from theoperational viewpoint.

8.2 8.33 kHz FREQUENCY MANAGEMENT

8.2.1 The introduction of 8.33 kHz channel spacing for Air Ground Communication in the UpperAirspace of the part of Europe experiencing a congested spectrum requires the developmentof a special Frequency Management Plan. The Strategy of this Frequency Management Planwas proposed by the EATMP 8.33 PMC, endorsed by the ICAO FMG and EANPG and is theresponsibility of the FMG.

8.2.2 The EANPG 40 acknowledged the key role of the Frequency managers of States and of theFMG in achieving the Frequency Management Plan, in conjunction with the 8.33 PSG whichincluded the following elements :

• Collecting the States existing 25 kHz frequency candidates for conversion to 8.33 kHzchannel spacing soon after October 2002;

• Ensuring development of the relevant allocation process for optimum spectrum utilisation;• Communicating regularly to the PSG the progress and problems encountered by the

EANPG FMG or by individual States in the implementation of the agreed 8.33 kHzfrequency management strategy; and



• Assessing the expansion needed in the area of 8.33 kHz operation, taking into accountthe current environment (airspace, traffic growth, new requirements etc.).

8.2.3 A positive and critical review of the existing 25 kHz frequencies allocations by the Statesthemselves is recommended, with the co-ordination support of EUROCONTROL. This is apreparatory step in the Frequency Management process.

8.2.4 Large frequency allocations in particular should be reviewed in terms of actual operations,properly tailored Service zone and Flight levels before 31 October 2002.

8.2.5 The transition to 8.33 kHz channel spacing is based on a mechanism of converting a numberof current 25 kHz ACC frequencies in Europe to 8.33 kHz channel spacing, potentiallyoffering 2 additional 8.33 channels.

8.3 8.33 kHz CHANNEL SPACING AND VHF SPECTRUM CAPACITY

8.3.1 The 8.33 kHz channel spacing releases VHF spectrum both in the 25 kHz and 8.33 kHzChannel Spacing environments.

8.3.2 Frequency management requires ever more stringent co-ordination between States. Stateshave requested EUROCONTROL to develop a number of procedures and software tools tohelp them in this task, in particular for monitoring the actual operations of the 8.33candidates in the agreed timeframe after October 2002.

8.3.3 Traffic levels are expected to increase. Thus, more ATC sectors and more flexibility in sectorarrangements are requested by States. The channel split from 50 kHz to 25 kHz was appliedfor the very same reason. Therefore, in the medium term, the creation of additional spectrumcapacity will facilitate the accommodation of increased traffic levels. Communications will beconducted within the limits of the VHF band as set by the FMG within the ITU dedicatedband, i.e. 117.975 - 137.000 MHz.

8.3.4 The spectrum gain of the channel split from 25 kHz to 8.33 kHz depends on two processes :

a) the conversion of a sufficient number of existing ACC frequencies from 25 kHz to8.33 kHz from 31st October 2002 to end of 2003; and

b) the planning of additional sectors using 8.33 kHz as soon as possible after 31October 2002 onwards.

8.3.5 Time schedule

8.4 INTERFERENCE RISK

8.4.1 The 8.33 kHz channel spacing has been implemented in such a way that no interferenceoccurs with 25 kHz in normal conditions (separation criteria and planning procedures).

8.4.2 In-advertant usage (i.e. mis-tuning) of a frequency in 25 kHz channel spacing but in a 8.33airspace can create serious interference in other areas. Frequency blocking in 8.33channel spacing (as experienced today with the 25 kHz channel spacing) has to be carefullymonitored. This has been considered during the development of the Implementation Plan.

8.4.3 In addition, the operational procedures detailed in this User Guide will limit the occurrence ofsuch phenomena:

• The flight plan will reflect the 8.33 capability of the flight to be conducted. This will allow afirst and fundamental check.

• When transmitting 8.33 kHz channels, the word “CHANNEL” shall be used by the flightcrew, ATS controllers and other ground personnel. Word “CHANNEL” will allow “uniqueidentification” which will avoid this type of mistuning.

• The flight crew is responsible for ensuring full operational compatibility with airspace to beoverflown.

• The new phraseology prescribed in ICAO SUPPS – Doc 7030/4, EUR/RAC, Table 1,allows ATS controllers, flight crew and other ground personnel to cover all the possiblesituations related to the 8.33 kHz channel spacing.(Refer to Annex I)

• Finally, the step-by-step and frequency planning method used in the FrequencyManagement Plan for implementing the new 8.33 channelling, will limit (as today in the25kHz channel spacing) the occurrence of such interference.



9. EQUIPMENT STANDARDS

The 8.33 kHz channel spacing standards and definition have been approved by thefollowing bodies:

9.1 AMCP / SARPS

9.1.1 The Aeronautical Mobile Communication Panel (AMCP) defined, through Standards AndRecommended Practices (SARPS), the 8.33 kHz Double Side Band (DSB) AmplitudeModulated (AM) carriers.

9.1.2 The Air Navigation Commission (ANC) and ICAO Council approved (November 1996) thisnew channel spacing as an amendment to Annex 10. It describes the characteristics of the8.33 kHz ground and airborne systems.

9.2 EUROCAE / MOPS

9.2.1 On the airborne side, the European Organisation for Civil Aviation Equipment (EUROCAE)produced the relevant Minimum Operational Performance Standards (MOPS) documentwhich is used by the Joint Aviation Authorities (JAA) for the certification of avionics. Thework on the MOPS was subsidiary to the work carried out at AMCP WG-B on the SARP.

9.2.2 The new version of the MOPS including 8.33 kHz operation was adopted by the EUROCAECouncil in December 1994 and published in March 1995 (ref. ED-23B).

9.3 RTCA / MOPS

9.3.1 In addition the RTCA SC-172 agreed in 1995 to produce a MOPS for 8.33 kHz operationbased on the EUROCAE MOPS. The final draft was adopted in August 1995 and is referredto as DO-186A.

9.4 AEEC / ARINC 716 SUPPLEMENT

9.4.1 The Airlines Electronic Engineering Committee (AEEC) produced a supplement to ARINC716 to cover the 8.33 kHz mode. ARINC 750 which specifies that the VDR provides thefunctionality of an AEEC 716 transceiver and hence covers the 8.33 kHz mode. Asupplement for the 8.33 kHz mode to ARINC 716 was adopted at the AEEC GeneralSession in October 1994.

9.5 ETSI / ETS 676



9.5.1 Finally, 8.33 kHz channel specification is covered by the European TelecommunicationStandardisation Institute (ETSI) in document ETS 676 under “Radio Transmitters andReceivers and Aeronautical Stations for the Aeronautical Mobile Service operating in theVHF Band”, approved in March 1997.



10. RETROFIT

10.1 AIR TRANSPORT EQUIPMENT TECHNICAL STANDARD

10.1.1 The existing aircraft fleet can be divided into two categories : digital aircraft with ARINC716/750 equipment utilising an ARINC 429 tuning interface and analogue aircraft withARINC 566A equipment fitted with the « 2 out of 5 » discrete wire tuning system. Thisdistribution gives rise to three main aircraft generation types :

• old generation aircraft (equipped with early analogue radios to be changed)• intermediate generation aircraft (equipped with analogue radios that can be upgraded);

and• new generation aircraft (basically digital aircraft using the A429 encoding scheme with

radios that can be upgraded).

10.1.2 According to relevant regulation (i.e. JAR/OPS 1 of April 1995 for Commercial Air Transportaviation), aircraft operating in the airspace of Mandatory Carriage will have to be equippedwith a minimum of two 8.33 kHz compatible radios.

10.2 AIR TRANSPORT AIRCRAFT RETROFIT

10.2.1 Technical effort required for old generation aircraft.

On an old generation aircraft (ARINC 500 equipped), the required effort depends on theretrofit philosophy. Choosing a new ARINC 700 transceiver will require a full rewiring ofthe VHF installation. However, if the decision is to select an ARINC 500 new radio, thetechnical effort amounts to power and ground inputs to the control panel. Indeed, detectionof 8.33 capable R/T with regard to the VHF Control Panel may use for analogue radios theencoding E wire and an additional +28 V DC supply to the 8.33 control panel (it can be asmuch as +/- 6 labour hours). In most cases, however, a complete new installation includinga replacement of the audio system is required. The tuning “2 out of 5” does not allow 8.33kHz spacing.

10.2.2 Technical effort for an intermediate generation aircraft.

As far as intermediate generation aircraft are concerned, installing an ARINC 500 radio willrequire, as above, a discrete wire and an additional 28 V DC supply on the control panel.The intermediate aircraft installation could be achieved during night stops or A, B, C and Dchecks. In most of the cases Service Bulletins are available for the 8.33 kHz retrofit.

10.2.3 Technical effort for new generation aircraft.

For last generation aircraft, only a software update or a new setup of the radiomanagement unit is necessary. As the intermediate ones the new generation aircraftinstallation could be achieved during night stops or during A, B, C, D checks.



11. SAFETY

11.1.1 The standards, procedures, systems and implementation plans developed for 8.33kHz havebeen designed to ensure that the new system will at least maintain the level of safety offeredby 25kHz system.

11.1.2 The assumptions of the initial 8.33kHz safety validation study have been reviewed in order tocover the new geographical area and states will be provided with key information that theyrequire to conduct their own appropriate analysis.

11.1.3 Each individual ICAO EUR State who, ultimately holds the legal responsibility for safety intheir national airspace, will need to develop their own detailed safety argument and safetyplans to govern the implementation and safety monitoring of the system.

11.1.4 The Launch Procedure (Chapter 12) and State Actions (Chapter 13) described below takeinto account all the recommendations of the Safety Validation Study and are aimed atproviding evidence of safe implementation of 8.33kHz on the national level and subsequentlyassure the preparedness of the States.

required• to highlight key items as provided in the 8.33 User Guide, edition 5.

Note: Two AICs are provided for 8.33 and non-8.33 States

13.3 ACTION ITEM 3 (HEX States) – “IFPS WARNING MESSAGE CO-ORDINATION” - PRIOR TO 21st FEBRUARY 2002

Each 8.33 HEX State is required to co-ordinate with CFMU the necessary changes in theCFMU Environment database in order to enable IFPS to output warning messages for non-8.33 equipped exempted aircraft with a requested flight level above FL245 within theairspace of the 8.33 HEX States.

Details regarding the IFPS output during this warning phase are provided in paragraph 4.4.Changes in the CFMU Environment Database should be co-ordinated by the Statesconcerned through their National Environment Co-ordinator.

13.4 ACTION ITEM 4 (ALL ICAO EUR Region) – “PUBLISH AIP AMENDMENT” -PRIOR TO 8th AUGUST 2002

In line with the requirement for publication of the 8.33 AIC, each State is required topublish an 8.33 AIP Amendment.

ICAO EUR Region States are encouraged to use the EUROCONTROL specimen 8.33 AIPAmendment proposed in Annex B of the Users Guide, ed 5.0, together with therecommended exemption text (refer to paragraph 7.4).

13.5 ACTION ITEM 5 (ALL ICAO EUR Region) – “LETTERS OF AGREEMENT” -PRIOR TO 31st MAY 2002

Each ICAO EUR Region State should confirm agreement in principle for theamendment of its Letters of Agreement as required for application from 31st October2002



A specimen Letter of Agreement, in line with the EUROCONTROL Common Format,Cross-border Letter of agreement is provided in Annex E of 8.33 User Guide, ed. 5.0, inorder to ensure that all relevant issues are covered when updating the Letters ofAgreement. States are recommended to use this to amend their LoA with neighbouringStates.

13.6 ACTION ITEM 6 (HEX States) – “FINAL IFPS CHECKING CO-ORDINATION” - PRIOR TO 5 SEPTEMBER 2002

Each 8.33 HEX State is required to co-ordinate with CFMU the necessary changes inthe CFMU Environment database in order to enable IFPS to include the 8.33 kHzHorizontal Expansion in the current 8.33 checking.

Details regarding the IFPS 8.33 processing are provided in Chapter 4. Changes in theCFMU Environment Database should be co-ordinated by the States concerned throughtheir National Environment Co-ordinator.

13.7 ACTION ITEM 7 (ALL ICAO EUR Region) – “ATS AWARENESS” - PRIORTO 31st OCTOBER 2002

Every ACC of each ICAO EUR Region State must ensure that all personnel concerned(especially in the Air Traffic Services) are aware of the implications of changesresulting from the 8.33 kHz Horizontal Expansion Programme and that the 8.33 aircraftstatus information available from the FPL is displayed/provided to the Air TrafficControllers by ensuring:

• that 8.33 status information distributed by IFPS is displayed/provided to Air TrafficControllers (i.e. warning of non-equipped aircraft for flights originating from outside theIFPS zone, or unknown equipage of aircraft where no flight plan exists), andNote: For aircrafts originating from within the IFPS zone, the flight plan will be rejected.

• that 8.33 and UHF status information in field 10 of the FPL is processed and displayedto ATC. This is particularly important for States outside the IFPZ, who do not receivethe warnings distributed by IFPS, and

• if possible, that field 18 information is processed, so that a non-equipped but exemptedaircraft is not tactically rerouted into airspace where no exemption is applicable, and

• if possible, that non-equipped status of those aircraft flying at a level below the Airspaceof Mandatory Carriage will be displayed to Air Traffic Controllers.Note: It is recognised that this may not be possible, but it is desirable in case of a non-equipped aircraft that has successfully filed a flight plan at a level below the Airspace ofMandatory Carriage subsequently requests a higher level during flight.

13.8 ACTION ITEM 8 (ALL ICAO EUR Region) – “SAFETY ANALYSIS” –PRIOR TO 31ST JULY 2002

It is the responsibility of each State to ensure that any safety analyses have beencarried out in accordance with the requirements prevailing in that State. In order toassist the States with these activities EUROCONTROL has produced the “8.33 SystemSafety Validation Study” which includes the system level safety audit and alsoprovides information to help the States to conduct their own appropriate analyses.



13.9 ACTION ITEM 9 (ALL ICAO EUR Region) – “LAUNCH PROCEDURE” –PRIOR TO 31ST JULY 2002

Each ICAO EUR Region State should ensure that the launch procedure is fully in placeand confirm as soon as possible to the 8.33 PSO that it can be fully supported asdescribed in Chapter 11 of 8.33 User Guide.

The Launch procedure incorporates State Actions of publication of AICs, AIPs, Reminderand Trigger NOTAMs amongst other actions.

13.10 ACTION ITEM 10 (ALL ICAO EUR Region) – “A/C OPERATORCOMPLIANCE” - PRIOR TO 31st OCTOBER 2002

Each ICAO EUR Region State should urge their national aircraft operators to becompliant by the 31st October 2002.

The retrofit and certification processes have to be supported with the purpose of all theconcerned A/C to be fully compliant with the 8.33 carriage requirement for aircraftoperating in the 8.33 HEX States.

In line with the ICAO SUPPS DOC 7030/4 EUR/RAC, a counting exercise to determine theaircraft rate of equipage will start in April 2002. This is being based on the flight plancarriage status indication measured through the CFMU IFPS.

13.11 ACTION ITEM 11 (8.33 HEX States) – “HANDLING STATE AIRCRAFT” –Prior TO 8th AUGUST 2002

Each 8.33 State must publish in its national AIP the 8.33 channels, the rules forhandling State aircraft including UHF capabilities.

These should include:

• How State aircraft will be handled within their 8.33 airspace• Confirmation that UHF aircraft will be allowed to fly without restriction above FL245 after

the 31st October 2002, prior to actual 8.33 channel implementation• The proposed UHF coverage following 8.33 implementation• Any special procedures that are intended to be offered in areas of no UHF coverage

within 8.33 airspace

Prior to the 30 March 2002 – Proposed Policy for handling States aircraft• Provide the above proposed policy information to the 8.33 Programme Support Office

8th August 2002- Official Publication• Publish the Policy for Handling State aircraft in the National AIP

13.12 ACTION ITEM 12 (ALL ICAO EUR Region) – “IMPLEMENTATION OF 8.33kHz FREQUENCIES” STARTING 31ST OCTOBER 2002

Each 8.33 HEX State should start progressive, co-ordinated implementation of8.33kHz spaced frequencies.



8.33 HEX preliminary actions - prior to July and October 2002:• Before July 2002 - Each State should submit the results of their frequency review

process for co-ordination by EUROCONTROL.• Before October 2002 - Each State should provide the 8.33 PSO with their list of the

existing 25 kHz frequencies to be converted to 8.33 kHz on or after 31 October 2002.

8.33 HEX post actions – starting 31st October 2002:• Update the COM2 Table to reflect the “8.33 channel spacing” converted frequencies

when these becomes operational.• To inform the 8.33 PSO of these updates.

And

Each ICAO EUR Region State should – starting 31st October 2002:

• Commence operations according to their revised, approved and published 8.33AIC/AIP/LoA requirements as of 31st October 2002 from 00:00 UTC

• Record safety related events and advise 8.33 Support Cell (using standard ATFMreporting forms or other if required).



14. PROCEDURES FOR THE INTRODUCTION OF 8.33 KHZ CHANNELSPACING IN ADDITIONAL STATES FIR/UIR

The ICAO-approved carriage requirement for 8.33 kHz capable radio equipment applies inthe whole ICAO EUR Region above FL 245 (i.e. the “Area of Mandatory Carriage”) forsafety reasons and to facilitate expansion. The introduction of 8.33 kHz channel spacing inadditional FIR/UIR is at all times possible when warranted by frequency shortageconsiderations, but only for operations above FL 245. To ensure the orderly addition ofFIR/UIR implementing 8.33 kHz channel spacing, it is essential that the following steps aretaken :

14.1 COORDINATE WITH THE ICAO EANPG FMG TO DETERMINE THEFEASIBILITY IN TERMS OF FREQUENCY PLANNING

• Requirements and planning for additional services.• Notification to the FMG and to EUROCONTROL of the existing services to be converted

in 8.33.• Frequency conversion and implementation• Planning of 8.33 new requirements through FMG planning procedures.

14.2 ADVANCE NOTIFICATION VIA AIC/AIP

• Determine an implementation date which is compatible with the requirements for thenew services and the aircraft operators’ retrofit capabilities, taking into account theFrequency Management Procedures.

• Notify withdrawal of the relevant exemptions and change the date in National AIP (ifsuch a date has been included).

• Publish AIC describing the planned changes, including the relevant dates.• Co-ordinate with the military authorities to ensure that the required UHF coverage is

provided or other means are available which can permit handling of State aircraft.

14.3 CO-ORDINATE WITH ADJACENT FIR/UIR

• Amend AIP and LoA (including contingency procedures).• Launch operation according to predefined procedures similar to those described in

chapter 11.

HORIZONTAL EXPANSION OF 8.33 kHz CHANNEL SPACING

IN THE VHF RADIO COMMUNICATIONS BAND

ABOVE FL245 IN THE ICAO EUR REGION – EFFECTIVE 31st OCT 2002

This AIC replaces AIC no........., which is hereby cancelled.

From 31 October 2002, (State) will withdraw previously published exemptions to the mandatorycarriage requirement of 8.33 kHz radio equipment.

1 INTRODUCTION

The ICAO Special Communications/Operations Divisional Meeting (Montreal, March/April 1995)decided that, in order to increase channel capacity, the VHF communications band should be furthersplit from 25 to 8.33 kHz channel spacing. It was noted that this measure was a near termimprovement for regions experiencing severe VHF frequency spectrum congestion, in anticipation ofthe development and implementation of the future digital VHF radio system. The correspondingamendment to Doc 7030 (serial No: EUR/NAT-S 97/9 -RAC/3) was approved by the Council of ICAOon 30 January 1998.

The carriage and operation of 8.33 kHz channel spacing capable radio equipment has beenmandatory throughout ICAO EUR Region since 7 October 1999.

The States that implemented 8.33 kHz channel spacing from 7 October 1999 are: Austria, Belgium,France, Germany, Luxembourg, the Netherlands and Switzerland.

The States participating in the 8.33 kHz Horizontal Expansion are: Bosnia & Herzegovina,Croatia, Czech Republic, Denmark, Estonia, Finland, FYROM, Hungary, Ireland, Italy, Latvia,Lithuania, Norway, Poland, Portugal, Slovak Republic, Romania, Slovenia, Spain, Sweden,United Kingdom and FR Yugoslavia. The majority of these States will remove their 8.33exemptions on the target date of 31 OCTOBER 2002.



2 PROCEDURE

This AIC provides information from ICAO Doc 7030 with respect to the following:

• operational procedures, including flight planning;• implementation procedures;• exemption conditions, for UHF equipped State aircraft;

The EUROCONTROL 8.33 kHz User Guide – Horizontal Expansion (Edition 5.xx), provides furtherdetailed information on the 8.33 kHz channel spacing operational environment. It is important that it ismade available to ATS providers and aircraft operators. Copies of the 8.33 User Guide can be obtainedfrom the EUROCONTROL Web site (http://www.eurocontrol.int/vhf833) or by mail (EUROCONTROL,DIS/833, 96 Rue de la Fusée, 1130 Brussels, Belgium).

3 IMPLEMENTATION

3.1 IMPLEMENTATION IN ICAO EUR REGION

From 7th October 1999 only 8.33 kHz equipped aircraft are allowed to operate in the ICAO EURRegion above FL 245, unless operating in accordance with published exemptions (aspublished in the relevant State AIP).

3.1.1 Operational procedures

As of the 7th October 1999, aircraft not equipped with an 8.33 kHz capable radio shall not be plannedto operate above FL 245 throughout the EUR Region.

Nevertheless, exemptions may be granted by States that are not part of the Horizontal ExpansionProgramme and will be published in their State AIP

In addition, State aircraft (Military / Police / Customs) not equipped with an 8.33 kHz capable radiowill be allowed to operate in the airspace designated for 8.33 kHz channel spacing operations,provided that they are infrequent users of that airspace and are UHF equipped. In general, they will beaccommodated on UHF channels.

Where UHF coverage is not fully available, State aircraft not equipped with 8.33 channel spacingequipment shall be excluded from 8.33 airspace unless special handling procedures are in place.However these procedures apply only to UHF equipped State aircraft.

Note: Infrequent user is one defined as not exceeding 30 hours flying time per airframe per year,within the airspace concerned.

3.1.2 Flight Planning Procedures

From the 1st of October 1998, in the filed flight plan (FPL) of an aircraft planned to operate in theICAO EUR Region above FL245,• the letter “Y” shall be inserted in field 10 of the flight plan, for aircraft equipped with 8.33 kHz

capable radio equipment; or



• the indicator “STS/EXM833“, shall be inserted in field 18, for aircraft which are not equipped butwhich are planned to operate in accordance with published exemption from the mandatory carriagerequirement.

Notes:- Absence of the letter Y shall be taken as a lack of 8.33 kHz capable equipment.- To determine whether the indicator “STS/EXM833“ may be inserted in the flight plan, it will benecessary to consult the exemptions published in the relevant State’s AIP.- State aircraft equipped with UHF, but not equipped with 8.33 kHz capable radio shall insert the letter“M” in field 8 and the letter “U” in field 10 of the flight plan, as well as “STS/EXM833” in field 18.

RPL listings submitted after the 4th October 2001 are not assumed to be 8.33kHz radioequipped. ALL information that is relevant to 8.33 processing must be provided in the RPL submittedto CFMU in the form of a NLST (New List) or RLST (Revised List) from 4th October 2001 onwards.

8.33 kHz equipped aircraft shall include under the EQPT/ element in Item Q of the RPL the letter "Y"together with ALL other equipment and capability information in conformity with FIELD 10 of the ICAOFPL.

In appropriate cases, the exemption indicator (STS/EXM833) shall be provided in Item Q of the RPL.

In case of a change in the 8.33 kHz capability status for a flight planned to operate in the ICAO EURRegion above FL 245 a modification message shall be sent with the appropriate indicator insertedand, in case of an RPL, this shall be sent not earlier than 20 hours before the EOBT.

Aircraft normally capable of operating above FL245, but planning to fly below this level shall,nevertheless, insert the appropriate indicator.

3.2 IMPLEMENTATION IN (8.33 State)

The ICAO Doc.7030 (serial No: EUR/NAT-S 97/9 -RAC/3) stipulating the mandatory carriage of 8.33kHz channel spacing compatible radio equipment applies to the whole ICAO EUR Region.

The date of Mandatory carriage and operation of 8.33 channel spacing capable radio equipment foraircraft operating above FL245 was 7 October 1999.

In (insert name of 8.33 State), the applicable exemptions will be withdrawn on 31 October 2002.Actual introduction of 8.33 kHz channels will commence on or following this date.

In (insert name of 8.33 State) parallel operation of 25 and 8.33 kHz spaced VHF channels within onesector will not be possible. Consequently, from the 31st October 2002, the flight plan of all aircraftrequiring the provision of a GAT air traffic service in the airspace designated for 8.33 kHz channelspacing operation will be rejected if not equipped with radios compatible with 8.33 kHz channelspacing.

Non 8.33 equipped State aircraft, equipped with UHF, which are infrequent users of the airspace of(insert name of 8.33 State), will be provided with UHF coverage (insert description of the UHFcoverage) or/and (according to State’s policy) will be handled with specific procedures to be insertedin (insert name of 8.33 State) AIP.

Aircraft VHF radio equipment in the ICAO EUR Region will nevertheless be required to be able to tuneto 25 kHz spaced channels and receive in an environment which uses offset-carrier systems (the so-called CLIMAX operation). Airspace users should take into account that both 25 kHz channel spacingand offset-carrier systems will continue to be used throughout Europe.

2. PROCEDURE

This AIC provides information from ICAO Doc 7030 with respect to the following:

• operational procedures, including flight planning;• implementation procedures;• exemption conditions, including explanation;

The EUROCONTROL 8.33 kHz User Guide – Horizontal expansion (Edition 5.xx), provides furtherdetailed information on the 8.33 kHz channel spacing operational environment. It is important that it ismade available to ATS providers and aircraft operators. Copies of the 8.33 User Guide can be obtainedfrom the EUROCONTROL Web site (http://www.eurocontrol.int/vhf833) or by mail (EUROCONTROL,DIS/833, 96 Rue de la Fusée, 1130 Brussels, Belgium).

3. IMPLEMENTATION

3.1 IMPLEMENTATION IN ICAO EUR REGION

From 7th October 1999 only 8.33 kHz equipped aircraft are allowed to operate in the ICAO EURRegion above FL 245, unless operating in accordance with published exemptions (aspublished in the relevant State AIP).

3.1.1 Operational Procedures

As of the 7th October 1999, aircraft not equipped with an 8.33 kHz capable radio shall not be plannedto operate above FL 245 throughout the EUR Region.

Where 8.33 kHz channel spacing is in operation, parallel operation of 25 and 8.33 kHz spaced VHFchannels within one sector will not be possible. Consequently, from the 31st October 2002, the flightplan of all aircraft requiring the provision of a GAT air traffic service in the airspace designated for 8.33kHz channel spacing operation will be rejected if not equipped with radios compatible with 8.33 kHzchannel spacing.

Aircraft VHF radio equipment in the ICAO EUR Region will still be required to be able to tune to 25kHz spaced channels and receive in an environment which uses offset-carrier systems (the so-calledCLIMAX operation). Airspace users should take into account that these offset-carrier systems willcontinue to be used throughout Europe.

Nevertheless, exemptions may be granted by States that are not part of the Horizontal ExpansionProgramme and published in their State AIP.

In addition, State aircraft (Military / Police / Customs) not equipped with an 8.33 kHz capable radiowill be allowed to operate in the airspace designated for 8.33 kHz channel spacing operations,provided that they are infrequent users of that airspace and are UHF equipped. In general, they will beaccommodated on UHF channels.

Where UHF coverage is not fully available, State aircraft not equipped with 8.33 channel spacingequipment shall be excluded from 8.33 airspace unless special handling procedures are in place.However these procedures apply only to UHF equipped State aircraft.



Note: Infrequent user is one defined as not exceeding 30 hours flying time per airframe per year,within the airspace concerned.

3.1.2 Flight Planning Procedures

From 1st of October 1998, in the filed flight plan (FPL) of an aircraft planned to operate in the ICAOEUR Region above FL245,• the letter “Y” shall be inserted in field 10 of the flight plan, for aircraft equipped with 8.33 kHz

capable radio equipment; or• the indicator “STS/EXM833“, shall be inserted in field 18, for aircraft which are not equipped but

which are planned to operate in accordance with published exemption from the mandatorycarriage requirement.

Notes:- Absence of the letter Y shall be taken as a lack of 8.33 kHz capable equipment.- To determine whether the indicator “STS/EXM833“ may be inserted in the flight plan, it will benecessary to consult the exemptions published in the relevant State’s AIP.

- State aircraft equipped with UHF, but not equipped with 8.33 kHz capable radio shall insert the letter“M” in field 8 and the letter “U” in field 10 of the flight plan, as well as “STS/EXM833” in field 18.

RPLs listings submitted after the 4th October 2001 will not be assumed to be 8.33kHz radioequipped. ALL information that is relevant to 8.33 processing must be provided in the RPL submittedto CFMU in the form of a NLST (New List) or RLST (Revised List) from 4th October 2001 onwards.

8.33 kHz equipped aircraft shall include under the EQPT/ element in Item Q of the RPL the letter "Y"together with ALL other equipment and capability information in conformity with FIELD 10 of the ICAOFPL.

In appropriate cases, the exemption indicator (STS/EXM833) shall be provided in Item Q of the RPL.

In case of a change in the 8.33 kHz capability status for a flight planned to operate in the ICAO EURRegion above FL 245 a modification message shall be sent with the appropriate indicator insertedand, in case of an RPL, this shall be sent not earlier than 20 hours before the EOBT.

Aircraft normally capable of operating above FL245, but planning to fly below these levels shall,nevertheless, insert the appropriate indicator.

3.2 IMPLEMENTATION IN (insert name of non-8.33 State)

17.7 ANNEX F - STATE AIRCRAFT

1. DEFINITION OF STATE AIRCRAFT

EUROCONTROL established the following principles to clarify what is to be considered asState Aircraft within the context of European Air Traffic Management, particularly in relation toexemption policies and special procedures. In formulating the principles, careful considerationwas given not to interfere with the general provisions of the Chicago Convention, article 3b,and to fully preserve the sovereignty of every State to define what State Aircraft are withintheir national borders. The sole purpose of the principles are to give clear guidance to the AirNavigation Service Providers on what constitutes State Aircraft in the European ATMenvironment.

PRINCIPLE 1 For ATM purposes and with reference to article 3(b) of the Chicago Convention, only aircraft used in military, customs and police services shall qualify as State Aircraft. Accordingly:

• -Aircraft on a military register, or identified as such within a civilregister, shall be considered to be used in military service and hencequalify as State Aircraft;

• -Civil registered aircraft used in military, customs and police serviceshall qualify as State Aircraft;

• -Civil registered aircraft used by a State for other than military,customs and police service shall not qualify as State Aircraft.

PRINCIPLE 2 A reporting mechanism should be available for cases where operators are suspected of having incorrectly claimed that their aircraft was used in military, customs and police services.

PRINCIPLE 3 States shall ensure compliance with the above mentioned recommendations and investigate reports of incorrect claims.

PRINCIPLE 4 States shall develop provisions/procedures as part of their rules of the air, and reports referred to in Principle 3 above be acted upon in accordance with Article 12 of the Chicago Convention.

2. UHF COVERAGE – HANDLING OF NON 8.33 STATE AIRCRAFT

The following additional information was available at the time of printing. As it is subject topossible changes, the concerned State(s) should be contacted for more details.

In the East of 12°E part of Austria,8.33 is implemented only above FL 335 and UHF equipped aircraft are allowed to fly betweenFL 245 and FL 335. Any expansion of the 8.33 implementation should be carefully studied inco-operation with the military authorities.

BELGIUM, NETHERLANDS, LUXEMBOURG - These States use the EUROCONTROLMaastricht UAC which is handling military aircraft flying GAT on UHF.

FRANCE - French ACCs are providing an adequate UHF coverage to military.

GERMANY - is handling military aircraft flying GAT on UHF. It also includes the delegated partof Austria.

SWITZERLAND - is using a limited number of UHF frequencies. Switzerland considers thatthis coverage is sufficient to provide the service for the military flying as GAT in a normalsituation.
