FAA Ground School Practice Test

During a night flight, what does the presence of a steady green light commonly signify about another aircraft's location?

1. The aircraft is on your right.

2. The aircraft is directly ahead.

3. The aircraft is on your left.

4. The aircraft is behind you.

The correct answer is: The aircraft is on your right.

The presence of a steady green light indicates that another aircraft is located to your right side. In aviation, the color codes for navigation lights are standardized: a steady green light is designated as the right side light of an aircraft, while a red light signifies the left side. Understanding these light signals is crucial for maintaining situational awareness and safe separation from other aircraft, especially during night flights when visual references are limited. The other options relate to interpretations of different light configurations. A steady green light specifically denotes the relative position to the right, making that interpretation vital for pilots to be aware of when navigating. Understanding the significance of these navigation lights helps pilots make informed decisions regarding their flight path and maneuvers.
