Should a pilot lose communication during a flight, which are the correct ways of trying to re-establish air-ground communication?

1. Use the company ground frequency
2. Contact other aircraft
3. Use the previous frequency
4. Use the pilot-to-pilot frequency
5. Use another frequency appropriate to the route.
6. Contact other aeronautical stations
7. Use the designated standby frequency

  • A
    2, 3, 5, and 6.
  • B
    4, 5, 6, and 7.
  • C
    1, 2, 5, and 7.
  • D

    1, 3, 4, and 6.

COMMUNICATIONS FAILURE

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 stations 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.

When an aeronautical station has been unable to establish contact with an aircraft station after calls on the frequencies on which the aircraft is believed to be listening, it shall:

a) Request other aeronautical stations to render assistance by calling the aircraft and relaying traffic, if necessary;
b) Request aircraft on the route to attempt to establish communication with the aircraft and relay traffic, if necessary.
