Which colors are used in a lighted helicopter's rotation beacon?

In a lighted helicopter's rotation beacon, the correct colors used are white, yellow, and green. This combination is significant for visibility and safety, especially in a variety of flight conditions. The white light typically provides strong illumination, while yellow and green are chosen for their visibility against different backgrounds and in different weather conditions.

The specific use of these colors aids in the identification of the helicopter and ensures that it can be seen by other aircraft and on the ground, which is essential for collision avoidance in busy airspaces. Understanding the color coding of helicopter beacons is crucial for both pilots and air traffic control personnel in maintaining situational awareness during flight operations.
