What color do civilian beacons flash during nighttime?

Civilian beacons flash alternating white and green signals during nighttime. This color combination is specifically designed to enhance visibility and ensure that the beacons can be easily recognized by pilots and other personnel navigating at night. The use of green along with white serves to distinguish civilian beacons from other signals, such as those used by military or emergency services, which often have different color sequences or patterns.

The alternating nature of white-green signaling is also crucial for maintaining compliance with aviation safety regulations, as it helps pilots to quickly identify the type of beacon and what it represents in terms of navigation and safety. Recognizing the specific color arrangements used for different types of beacons is essential knowledge in aviation practices, contributing to overall situational awareness in flight operations.
