AIRPORT OPERATIONS REFERENCE GUIDE

CHENNAI INTERNATIONAL AIRPORT

(VOMM)

Warning: Though this manual is prepared with full caution to make it as close to realistic procedure

as possible at the time of publication, but real world procedures are subject to updates based on

various Authorities. This manual is not meant to be used in real world aviation and limited only to flight

simulation particularly in IVAO network. Under no circumstances, IVAO India and any of its division

staff is responsible for any act whatsoever performed by anyone dead or alive.

ACKNOWLEDGEMENT

This briefing was created to more realistically simulate the airport

procedures at Chennai International Airport (VOMM) on the IVAO

network. This document includes a lot of the necessary information

needed for flying inbound and outbound of VOMM, including all the

runway information, parking information, taxi procedure and VFR

operations.

The contents of this briefing are for simulation purpose only. IVAO India or

IVAO is not associated with the Directorate General of Civil Aviation, India

or any other commercial/military aviation governing bodies or authorities.

The operations manual contains information to be used at VOMM only

when flying on the IVAO Network to have a feel of real world procedures.

To make the most out of this manual, we strongly recommend reading

through the ATC-Pilot Phraseology Guide for India, which can be found at:

www.ivao.in/hq/policies/#Phraseology

We would like to sincerely thank IVAO-IN Division Director and IVAO-IN

Division Assistant Director for providing proactive support, insight and

guidance for preparing operations reference guide.

IVAO India division is also thankful to other IVAO-IN staffs and all the

people who anonymously helped in providing real world procedure data

from reliable sources to give a final shape to this information guide. We are

grateful for their cooperation and support.

Regards,

IVAO – IN Division

TRANSPONDER OPERATING PROCEDURE

It is advised that Pilot in Command (PIC) must keep the transponder mode STBY or SQUAWK STBY on all taxiways and parking stands.

Pilot must keep the transponder in TCAS mode or SQUAWK Charlie on entering the runway and in air throughout the flight

Departing ACFT : PIC should switch to SQUAWK C only after receiving line up or takeoff clearance and SQUAWK STBY is always practiced behind the holding point of active runway

Arriving ACFT : It is responsible for PIC to switch transponder to STBY mode as soon as vacating the active runway without any further instruction from controllers

Transponder Codes : Controllers usually assign reserved transponder codes when online. In case the controller is offline, it is mandatory for PIC to squawk 1200 for VFR flight and squawk 2000 for IFR flight.

Reserved Transponder Codes for Chennai FIR:

International Domestic

0600 – 0677 2700 – 2777 0200 – 0237

Special Transponder Codes: 7700 – Emergency | 7600 – Radio Failure

OUTBOUND TRAFFICS

Pre-Departure Clearance:

Pilots can get pre-departure clearance on Chennai Ground Frequency 121.9 since no separate frequency is available for getting pre-departure clearance.

On initial contact, it is advised that PIC should report parking stand and current ATIS information identifier.

Data Link Departure Clearance (CPDLC):

In IVAO, pre-departure clearance can be obtained using datalink through www.virtual-cpdlc.com. This service is available only if mentioned in ATIS that “Pre-departure clearance available at www.virtual-cpdlc.com”. Pilot shall acknowledge clearance within 5 minutes after receiving clearance.

In the event of any doubts or system-related difficulties, voice procedures shall be resumed. If the request is rejected, pilot shall revert to voice procedure.

Push-back operations:

Push-back and start-up clearance is required for all stands. Push-back should be initiated facing specific direction as instructed by ATC to ensure safe and expedite traffic flow on ground.

During Gate Hold in force due to traffic congestion, ATC may deny or delay push-back clearance. Pilots are requested to be patient in such occasions.

Taxi operations:

PIC should strictly follow assigned taxi routes and all hold short instruction to avoid traffic collision. Following wrong taxi routes may sometimes lead to closure of some controlled movement areas. In case, pilot lost the route or in confusion he can request for progressive taxi.

Departure:

After airborne pilot shall initially climb to FL060 through any of the following cleared standard RNAV Departure. Meanwhile you will be transferred to APP/DEP for further climb.

Vacation from RWY 12/30 – hold position on taxiway as soon as vacating

Taxi to Gate:

PIC should follow instructed taxi routes to assigned parking stand.

COMMUNICATION FAILURE UNDER RADAR VECTORS

Radio failure prior interception of final approach course

ACFT should maintain last assigned altitude or 3000’

(whichever is higher) and DCT to MMV VOR to join holding

Radio failure after interception of final approach course

ACFT can continue approach, if visual and land or go around and

carryout missed approach procedure and join MMV VOR

holding After entering hold, carry out published ILS or VOR procedure for RWY 07

It is recommended to simulate radio failure only when advised by trainer or examiner during On Job Training (OJT) or Controller Practical Examination. When simulating communication failure pilot should follow the communication failure procedures and must squawk 7600. If the pilot seemed to be deviating from course, text communication will be established by controllers.

Note: The above radio failure procedure strictly applicable only when aircraft is on radar vectors

Page 10

CHENNAI OCEANIC RADIO

Chennai Oceanic Radio Frequency

126.15 MHz

East Bound Traffic following SIDAT and OXENA RNAV DEP must start giving position report from waypoint IDASO / AVNOS / GIRNA to Chennai Oceanic Radio in voice or using CPDLC.

Note : Pilots flying east bound please read Indian Oceanic Procedure in following link http://www.ivao.in/resources/india-oceanic-procedures/

VFR OPERATIONS

VFR operations are permitted in Chennai if the airport is at Visual Meteorological Conditions (VMC).

Parameter VMC conditions

Flight Visibility Above FL100 – 8km Below FL100 – 5km

Ceiling 1500’ AGL

PIC is responsible for clear of clouds and in sight with surface

If the airport doesn’t meet VMC conditions, VFR operations shall be suspended. In that case, controller may ask for intentions.

Pilot may wait until airport turns to VMC conditions Pilot may ask for special VFR or SVFR clearance if the visibility is

above 1500m Or Pilot may disconnect

Note: Simulating VMC is allowed only in Exams and Training and only if approved by Examiner or Trainer

Aerodrome circuits:

Aerodrome circuit altitude: 1100’ Elevation: 52’

Standard Circuit: To avoid flying over restricted airspace(Ref Page13) standard circuit pattern is designed for following runways

RWY 07, RWY 12 Left Hand Circuit

RWY 25, RWY 30 Right Hand Circuit

Tower Control Zone:

25 NM around MMV VOR

GND/ ’

Page 12

Transition through Control Zone:

VFR Pilot should establish two way communication with tower before entering tower control zone. On initial contact PIC should give position report with respect to MMV followed by intentions that to be carried out in control zone

VFR Departure and Arrivals from VOMM always remain on tower frequency when flying within Tower Control Zone

Important: The greatest part of tower controller is looking out the window and visually scanning the runways and airport area through eyes to keep situation awareness. The standard IVAC “Tower” radar mode may be used to simulate Uncertified Tower Radar display for quick reference of general situational awareness. Hence, No Radar Services and No Radar Traffic Advisories (i.e radar vectors and radar separation is not provided within Tower Control Zone).

Page 13

PROHIBITED, RESTRICTED, AND DANGER AREAS

PIC of VFR flight is responsible to avoid flying over the following boundaries. However, for IFR flights ATC is responsible.
