FAA Military Competency Practice Exam

If a pilot sees only the green light of another aircraft while in flight, who has the right-of-way?

1. The pilot of the aircraft showing the white light.

2. The pilot of the aircraft showing the red light.

3. The pilot of aircraft #1, as it is to the right.

4. No one; they need to avoid each other.

The correct answer is: The pilot of aircraft #1, as it is to the right.

When a pilot observes only the green light of another aircraft in flight, it indicates that the other aircraft is likely approaching from the right side. In aviation, the rules of right-of-way dictate that when two aircraft are approaching each other, the one on the right has the right-of-way. This is guided by the principle that pilots must always maintain awareness of their position relative to other aircraft and take action to avoid collisions. The green light is typically positioned on the starboard (right) side of an aircraft, while the red light is located on the port (left) side. Hence, if a pilot sees a single green light, it suggests that the other aircraft is primarily displaying its right side and is in a position that warrants the pilot to yield to the one on the right. This situation underscores the importance of understanding and interpreting the navigation lights correctly to enhance safety in the airspace.
