11.1.1.2 Radio Failure
It could be that your (or the other station) equipment’s malfunctioning. It is
possible that your receiver has failed but you are still transmitting satisfactorily.
In VMC and operating under VFR (visual flight rules) some aircraft still operate
with no radio fitted, therefore unless you need an ATC service there is no cause
for concern! However, if you do need a service (for example to join a traffic
pattern to land) then you should follow the GENERAL PROCEDURE outlined here:
- Attempt communication on another frequency.
- If these attempts fail, continue to transmit your message twice on
the designated frequency.
- If you know that your receiver has failed, transmit reports (or positions)
at the scheduled times on the frequency n use.
Note: ICAO requirement states that “An aircraft which is receiving Air Traffic Control or
Advisory Service shall also transmit information regarding the intent on of the pilot-in-
command with respect to the continuation of the flight.”
11.1.1.3 Other Radio Failure
How else could you inform ATC of your radio failure?
SSR Code - squawk 7600
This code appearing on a radar screen informs the controller that the aircraft
concerned has radio problems.
11.1.2 Rules of the Air
The Rules of the Air (Annex 2 to the ICAO convent on) says that in Visual
Meteorological Conditions (VMC) the aircraft with communications failure shall:
- Continue to fly in VMC ( keep clear of cloud).
- Land at nearest suitable aerodrome.
- Report arrival by the most expeditious means to the appropriate ATC
unit (telephone ATC).
Note 1: “In addition, the aircraft when forming part of the traffic pattern (i.e. in the circuit to
land) at a controlled aerodrome shall keep a watch for instructions as may be issued by visual
signals”
Note 2: “Controlled VFR” is common in other countries and requires 2-way communications.
