What is the color and orientation of the position lights for navigation on civil airplanes?

The correct response identifies that the left side of civil airplanes has red position lights, while the right side is equipped with green position lights, and the rear features white lights. This color-coding system is essential for the safe operation and visibility of aircraft, particularly during night flying or in conditions of reduced visibility.

The left and right colors help pilots determine the orientation of another aircraft from a distance. When two airplanes approach each other, the red light on one aircraft indicates its left side, while the green light on the other indicates its right side. This clarity in identification helps in assessing the flight path and maintaining safe separation between aircraft. The white light at the rear aids in the visibility of the aircraft from behind, further enhancing situational awareness.

Position lights not only aid in navigational functions but also play a significant role in collision avoidance, allowing pilots and air traffic controllers to easily identify the direction in which an aircraft is heading based on the light configuration.
