Six lights. Learn them in five minutes.
If a pilot loses the radio, they set their transponder to 7600 and look at the tower. The controller aims a narrow, very bright beam (red, green or white, steady or flashing) at that one aircraft. What it means depends on where the plane is. Tap any row to fire that light.
| Signal | Aircraft in flight | Aircraft on the ground |

From the light signal table in 14 CFR §91.125. Flashing green for taxi applies to aircraft. The full table also has a column for vehicles and people on the field.
PICK A SIGNAL
Tap a row in the chart to see what each signal says to a pilot.
You're the pilot. Read the tower.
A light flashes from the tower and you're told where you are. Pick what it means. A right answer scores a point and builds your streak (every 5 in a row adds 2 seconds). A wrong answer costs you 3 seconds.
READY?
Sixty seconds, as many signals as you can read.
How pilots answer a light
In the air, by day
Rock the wings.
At night
Flash the landing lights or the navigation lights.
On the ground, by day
Move the ailerons or the rudder.
Three codes every controller knows
7500
Unlawful interference (hijack).
7600
Lost communications. The radio is dead, so watch the tower for lights.
7700
General emergency. In the game, a plane that runs out of fuel declares MAYDAY.
