INDICATING OF TRANSMITTINGFREQUENCY

As the aeronautical station operator generallyguard more than one frequency, the callshould be followed by an indi-cation of thefrequency used, unless other suitable means of

identifying the frequency are known to exist.

When no confusion is likely to arise, only thefirst two digits of the HF (in kHz) need be used

to identify the transmitting channel.

COMMUNICATION WATCH/HOUR OF


50/81

Aircraft shall continuously guard the VHF emergency frequency 121.5

MHz in areas or over routes where the possibility of interception of

aircraft or other hazardous situations exist, and a requirement has been

established by the appropriate authority.

The user of the air-to-air VHF communications channel shall ensure

that adequate watch is maintained on designated ATS frequencies, the

frequency of the aeronautical emergency channel, and any other

mandatory watch frequencies.

5.2.2.1.1.2 / 5.2.2.1.1.4

COMMUNICATION WATCH/HOUR OF

SERVICE (Cont)

COMMUNICATIONS FAILURE (1)


51/81


When an aircraft station fails to establish contact with the aeronautical station

on the designated frequency, it shall attempt to establish contact on another

frequency appropriate to the route. If this attempt fails, the aircraft station shall

attempt to establish communication with other aircraft or other aeronautical

station on frequencies appropriate to the route. In addition, an aircraft operating

within a network shall monitor the appropriate VHF frequency for calls from

nearby aircraft.

5.2.2.7.1.1 / 5.2.2.7.1.2 / 5.2.2.7.1.2.1

AIR-GROUND

If at above fail, the aircraft station shall transmit its message twice on the

designated frequency(ies), preceded by the phrase TRANSMITTINGBLIND

and, if necessary, include the addressee(s) for which the message is intended.

In network operation, a message which is transmitted blind should betransmitted twice on both primary and secondary frequencies. before changing

frequency, the aircraft station should announce the frequency to which it is

changing.



52/81


Receiver Failure

5.2.2.7.1.3.1

When an aircraft station is unable to establish

communication due to receiver failure, it shall transmit

reports at the scheduled times, or positions, on the

frequency in use preceded by the phrase

TRANSMITTING BLIND DUE TO RECEIVER

FAILURE. The aircraft station shall transmit the intended

message, following this by a complete repetition. During

this procedure, the aircraft shall also advise the time of

its next intended transmission.



53/81


Receiver Failure

5.2.2.7.1.3.2 / 5.2.2.7.1.3.3

An aircraft which is provided with air traffic control or

advisory service shall, in addition to complying with at above,

transmit information regarding the intention of the pilot in

command with respect to the continuation of the flight of the

aircraft.

When an aircraft is unable to establish communication due to

airborne equipment failure it shall, when so equipped, select

the appropriate SSR code to indicate radio failure.

HF MESSAGE HANDLING


54/81

HF MESSAGE HANDLING

When operating within a network, an aircraft station should, in

principle, whenever communications conditions so permit, transmit its

messages to the stations of the network from which they can be most

readily delivered to thir ultimate destinations. In particular, aircraft

reports required by air traffic services should be transmitted to the

network station serving the flight information centre or area control

centre in whose area the aircraft is flying. Conversely, messages to

aircraft in flight should, whenever possible, be transmitted directly to

the aircraft by the network station serving the location of the originator.

5.2.3.1.1 / 5.2.3.1.2

Message passed from an aircraft to a network station should, whenever

possible, be intercepted and acknowledge by other stations of the

network, which serve locations where the information is also required.
