FAA Sport Pilot Airplane (SPA)RegulationsEasy

A sport pilot loses radio communication while approaching to land at a towered airport and observes the control tower flash a steady red light signal at the aircraft while it is in the traffic pattern. What does this signal mean?

  1. AAirport unsafe, do not land
  2. BReturn for landing at a later time
  3. CGive way to other aircraft and continue circling
  4. DCleared to land
Show answer & explanation

Correct answer: A. Airport unsafe, do not land

A steady red light signal directed at an aircraft in flight means the airport is unsafe and the pilot should not land. A flashing red light while in flight means the same thing but also directs the pilot to continue circling; a steady red is specifically 'airport unsafe, do not land.'

Why the other options are wrong

  • B. 'Return for landing' is signaled by a flashing white light, not red.
  • C. A flashing red light, not steady red, means give way and continue circling.
  • D. A steady green light, not red, signals clearance to land.

ATC Light Gun Signals

Visual signals used by a control tower to communicate with aircraft that have lost radio communication.

  • Steady green (in flight) = cleared to land
  • Flashing red (in flight) = airport unsafe, continue circling
  • Steady red (in flight) = airport unsafe, do not land

Memory trick: 'Red means dread — don't land when it's steady red.'
