- AX-BC is requested to standby on the frequency
- BX-BC is requested to standby as the radar controller is busy
- CX-BC is requested to standby for radar vectors
- DX-BC is requested to switch to standby position

Question 6 · 090 04 Communication failure
An aircraft station fails to establish radio contact with an aeronautical station on the designated frequency. What action is required by the pilot:
- AReturn to the airport of departure
- BContinue the flight to the destination airport without any communication
- CAttempt to establish contact with the station on an alternative frequency
- DLand at the nearest airport without an ATC unit
Show the answer+
Answer: C. Attempt to establish contact with the station on an alternative frequency
If an aircraft station cannot establish contact on the designated frequency, it tries another frequency appropriate to the route, then other aeronautical or aircraft stations (ICAO Annex 10 Volume II).
Question 7 · 090 04 Communication failure
An aircraft on an IFR flight in VMC experiences radio communication failure. The aircraft is assumed to :
- ALand at the alternate aerodrome
- BLand at the destination aerodrome
- CLand at the nearest suitable aerodrome
- DReturn to the aerodrome of departure
Show the answer+
Answer: C. Land at the nearest suitable aerodrome
An IFR flight in VMC that loses radio communication continues to fly in VMC, lands at the nearest suitable aerodrome and reports its arrival to ATC (ICAO Annex 2 and SERA.14083).
Question 8 · 090 06 VHF propagation and allocation of frequencies
Which is the frequency band containing frequencies of the Aeronautical Mobile Service?
- A108.000 - 117.975 MHz
- B1810 - 2850 KHz
- C118.000 - 136.975 MHZ
- D11650 - 13200 KHz
Show the answer+
Answer: C. 118.000 - 136.975 MHZ
The VHF aeronautical mobile service (air-ground voice) uses the 118.000 to 136.975 MHz band. 108.000 to 117.975 MHz is used by VOR and ILS localisers.
