If radio communication with a tower fails, tower controllers can communicate with aircraft using
- A.flashing runway edge lights in Morse code
- B.the rotating beacon turned on and off
- C.a light gun with steady and flashing red, green, and white signals
Correct answer
C. a light gun with steady and flashing red, green, and white signals
Why
Controllers use a light gun projecting colored signals, such as steady green for cleared to land for aircraft in flight, when radio contact is lost. Runway lights and the beacon are not used as a coded signal system.
