You are flying on the base leg of a nighttime approach to an aerodrome when you observe a steady red light directed at you from the control tower. What is the appropriate action to take?

  • A

    Give way to other aircraft and keep circling.

  • B

    Return to aerodrome and wait for permission to land.

  • C

    Leave the circuit pattern immediately, radio required at this aerodrome.

  • D

    Land at your discretion.

Refer to figure.
When any issue with radio communication between the aerodrome tower and an aircraft occurs, the tower controller may choose to indicate light signals to communicate with the pilot. These signals have different meanings depending on whether the aircraft is on the ground or in flight. When you see a red steady light during flight, you should give way to other aircraft and continue circling.
