Final answer:
The purpose of navigation lights is to help a pilot safely navigate through the air by communicating the position and direction of the aircraft.
Step-by-step explanation:
The purpose of navigation lights is to help a pilot safely navigate through the air. These lights are usually installed on aircraft and are used to communicate the position and direction of the aircraft to other pilots and ground personnel. For example, red lights are typically located on the left wingtip, green lights on the right wingtip, and a white light on the tail of the aircraft.
By following standardized lighting configurations and patterns, pilots can easily identify other aircraft in the vicinity and avoid potential collisions. Navigation lights are especially important during nighttime and low-visibility conditions, when visual cues from other aircraft are crucial for safe flight.
