If an aircraft is displaying a green light, what should the observer understand?

When an aircraft displays a green light, it indicates that the observer should understand the aircraft is approaching from the right. This is based on international aviation lighting standards, where a green light is positioned on the right side of the aircraft. Pilots are trained to use this color coding to determine the relative position and direction of other aircraft during flight, especially during approaches and landings.

The significance of this information lies in ensuring situational awareness and safe navigation, especially in crowded airspace or on the ground. Properly interpreting the light signals helps prevent mid-air collisions and other dangerous situations. Thus, recognizing a green light as a signal of an approaching aircraft from the right is essential for maintaining safety and effective communication among pilots.
