Key concepts
Radio failure in VMC.
Continue in VMC, land at the nearest suitable aerodrome and report arrival by the quickest means. Squawk 7600.
Radio failure in IMC.
Maintain the last assigned speed and level (or the minimum flight altitude if higher) for 20 minutes (7 minutes in radar airspace) after the trigger, then continue as filed.
- Squawk 7600
- Try other frequencies and 121.5 MHz
- Transmit blind
Sample questions
Q1The transponder code to set after a radio communications failure is:
- 7600
- 7500
- 7700
- 7000
Show the answer
Answer: A. 7600 7600 indicates loss of communications.
Q2An aircraft suffering a radio failure in VMC should:
- Climb to the highest level and continue to destination
- Continue in VMC, land at the nearest suitable aerodrome and report its arrival by the quickest means
- Return to the departure aerodrome whatever the weather
- Squawk 7700 and descend to 1 000 ft
Show the answer
Answer: B. Continue in VMC, land at the nearest suitable aerodrome and report its arrival by the quickest means In VMC the aircraft continues to fly in VMC, lands at the nearest suitable aerodrome and reports its arrival.
Q3In airspace where radar is used for separation, the aircraft with a radio failure maintains the last assigned speed and level, or the minimum flight altitude if higher, for:
- 1 hour
- 7 minutes
- 30 minutes
- 20 minutes
Show the answer
Answer: B. 7 minutes In a radar environment the period is 7 minutes after the latest of: reaching the last assigned level, setting 7600, or failing to report at a compulsory reporting point.
Q4A series of red flashes from the control tower to an aircraft in flight means:
- Land at once
- Airport unsafe, do not land
- Cleared to land
- Give way to other aircraft and continue circling
Show the answer
Answer: B. Airport unsafe, do not land Red flashes mean the aerodrome is unsafe and landing is not permitted.
