How can a military airport be identified at night?

1. By the color of the approach lights

2. By dual peaked (two quick) white flashes between green flashes

3. By the presence of red blinking lights

4. By a single steady white light

The correct answer is: By dual peaked (two quick) white flashes between green flashes

A military airport can be identified at night primarily by observing a specific signaling method used in its approach lighting system. The dual peaked white flashes, specifically the two quick flashes followed by green flashes, indicate the presence of a military airport. This signaling technique is standardized to ensure that pilots can distinguish military airfields from civilian ones after dark, facilitating better navigation and aiding in flight safety. The color and pattern of the lights are significant because they serve as critical clues about the type of airport. The unique flash pattern helps pilots recognize their environment, especially in low visibility conditions. Other types of lights present at airports often do not follow this specific signaling format that incorporates both the dual white flashes and green, making this identification method reliable. Understanding these visual signals allows pilots to make informed decisions about their approach and landing, particularly when operating in areas that may have both civilian and military flight zones.
