What does a flashing green light mean on a plane?

A flashing green light on a plane signifies a couple of different things, depending on the context. In aviation, lights play a crucial role in communicating messages to both pilots and ground personnel. One of the primary uses of lights on an aircraft is to enhance its visibility during flight and on the ground. In this regard, the flashing green light primarily serves as a signal to ground personnel.

When the green light is flashing while the aircraft is on the ground, it indicates that the plane is ready to taxi or is currently taxiing. This signal is important for ground crew members or air traffic controllers to efficiently manage the flow of aircraft on the airport apron or taxiway. The flashing green light allows them to identify which planes are in motion, enabling them to direct other aircraft safely.

During flight, the flashing green light can have a different meaning. On some aircraft, a green light might be installed on the wingtips or tail to indicate that the landing gear is in the process of retracting or extending. This function assists the flight crew in monitoring and confirming the status of the landing gear, ensuring its proper operation during takeoff or landing.
