What does a flashing green air traffic control signal indicate to a pilot on the runway?

A flashing green air traffic control signal indicates that the plane is cleared to taxi. In aviation, different colored signals and patterns convey specific instructions to pilots. A flashing green signal is specifically designated for ground movement and indicates that the aircraft is authorized to taxi on the runway or taxiway.

Understanding the context within air traffic control communications is essential. For example, a solid green signal would mean clearance for takeoff or landing, depending on the situation, while red signals serve to instruct pilots to stop. Thus, the flashing green signal serves a clear and critical purpose in facilitating safe ground operations at the airport, making it essential for pilots to recognize and respond appropriately.
