What does a flashing green light signal indicate for a pilot?

A flashing green light signal indicates that the pilot is cleared to taxi. This signal is part of the visual communication methods used at airports to convey important instructions to pilots. When a green light is flashing, it signifies that the aircraft can move on the taxiways, making it essential for pilots to be aware of this signal when preparing to maneuver on the ground.

In the context of air traffic control, knowing the meanings of light signals is crucial for maintaining safety and efficiency in airport operations. Each signal conveys specific instructions to pilots, allowing for a standardized means of communication when radio contact may not be possible or as an additional visual cue. Understanding the significance of a flashing green light helps pilots ensure that they are responding appropriately to ground control directions.
