What color are the formation lights on the aircraft?

Formation lights on the F/A-18 E/F aircraft are designed to enhance visibility and situational awareness during flight, particularly when flying in formation with other aircraft. The correct choice indicates that the formation lights are green. These lights serve to provide a clear visual identification of the aircraft's position and orientation to others in a formation, helping pilots maintain proper spacing and coordination.

In aviation, specific colors are used for various purposes, and the use of green for formation lights is standardized. This color is bright enough to be seen in various lighting conditions and is distinct from other lights on the aircraft, such as navigation and anti-collision lights, which have different functions and colors. This attention to color coding is essential for safety and effective communication among pilots in a flight formation.
