ATC issues a clearance with a void time of 1015. The pilot is unable to depart by that time. By what time must the pilot notify ATC of their intentions?
- A1020
- B1015
- C1030
- D1045
Show answer & explanationAnswer & explanation
Correct answer: D. 1045
Per AIM 4-3-4, if a pilot does not depart by the clearance void time, the pilot must notify ATC as soon as possible, but no later than 30 minutes after the void time; 1015 plus 30 minutes is 1045.
Why the other options are wrong
- A. 1020 is only 5 minutes after void time, too early to be the deadline.
- B. 1015 is the void time itself, not the notification deadline.
- C. 1030 is 15 minutes after void time, not the 30-minute maximum.
Clearance Void Time
A clearance void time requires the aircraft to be airborne by that time; if unable, the pilot must notify ATC within 30 minutes after the void time.
- Void time = deadline to be airborne
- Failure to depart voids the clearance
- Pilot must contact ATC within 30 minutes if not airborne
Memory trick: Void time plus 30 = the deadline to call
