A steady green light in flight indicates?

A steady green light during flight is an indication that the aircraft is cleared to land. This signal is part of air traffic control communication, which uses light signals to convey instructions to pilots, especially in situations where radio communication may not be possible.

The green light specifically denotes that the aircraft can proceed with the landing approach, indicating that the runway is clear and that no obstacles are present for a safe landing. Understanding this sign is critical for pilots as it directly affects their actions during the landing phase of flight.

While there are other signals for different phases of flight, such as a steady green light at the departure airfield indicating clearance for takeoff, the context of this question specifically pertains to in-flight signals, thus reinforcing that a steady green light conveys the clear message that the aircraft is cleared to land.
