When a controlled VFR flight transiting a Control Zone suffers a communications failure, what shall the pilot do?

1. Continue to fly in either VMC or IMC as meteorological conditions dictate.
2. Continue to fly in VMC.
3. Leave the Control Zone by the shortest route taking into account the weather conditions, obstacles and known areas of high traffic density
4. Land as soon as possible at the nearest controlled aerodrome in the Control Zone, watching for visual signals when in the aerodrome traffic circuit.
5. Land at the nearest suitable aerodrome.
6. Report the aircraft`s arrival by the most expeditious means to the appropriate ATS Unit.

  • A
    2, 4, and 6
  • B
    1, 3, 4, and 6
  • C
    2, 3, 5, and 6
  • D
    1, 5, and 6

In case of communication failure in VMC, normally what needs to be done is 2, 5 and 6. However, since the intention was to cross control zone at the beginning it is desirable to do that first as it is probably busy with IFR traffic.


ICAO Annex 2

3.6.5 Communications
3.6.5.2 Communication failure. If a communication failure precludes compliance with 3.6.5.1, the aircraft shall comply with the voice communication failure procedures of Annex 10, Volume II, and with such of the following procedures as are appropriate. The aircraft shall attempt to establish communications with the appropriate air traffic control unit using all other available means. In addition, the aircraft, when forming part of the aerodrome traffic at a controlled aerodrome, shall keep a watch for such instructions as may be issued by visual signals.

3.6.5.2.1 If in visual meteorological conditions, the aircraft shall:

a) continue to fly in visual meteorological conditions; land at the nearest suitable aerodrome; and report its arrival by the most expeditious means to the appropriate air traffic services unit;
b) if considered advisable, complete an IFR flight in accordance with 3.6.5.2.2.
