What does a steady green light on the ground indicate?

A steady green light on the ground is an important signal for pilots, particularly when they are approaching an airport or are on the runway. It indicates that the aircraft is cleared to land. This signal is part of the air traffic control’s system of visual aids designed to guide pilots safely during the landing phase of flight.

When a pilot sees a steady green light, it confirms that the flight is following the appropriate procedures and can safely proceed with landing without any restrictions or pending actions. This light serves to ensure communication between air traffic control and the aircraft, promoting safety in airport operations.

Understanding the meanings of these signals is crucial for pilots, as other indications, such as red lights, would imply hold or stop conditions. Therefore, recognizing a steady green light clearly indicates that the aircraft is authorized to land, reinforcing the need for pilots to be familiar with visual cues in and around the airport environment.
