What does seeing a green light on another aircraft signify?

Seeing a green light on another aircraft signifies that you have the right of way. In aviation, navigation lights are color-coded according to standard conventions. The green light is located on the right wingtip of an aircraft, and it indicates the relative position of that aircraft to yours. If you see a green light, it means the aircraft is approaching from the right side, and when considering the rules of the air, the aircraft with the green light will have the right of way over other aircraft.

Understanding this helps pilots make safe navigation decisions, particularly in cases where aircraft are on converging paths. Proper recognition of navigation lights and their meanings is essential in maintaining safety and avoiding mid-air collisions.
