FAA Ground School Practice Test

How can a military airport be identified during nighttime operations?

1. A rotating beacon that emits continuous green flashes

2. Dual Peaked white flashes between green flashes

3. Single steady green light markers

4. Two slow white flashes between red flashes

The correct answer is: Dual Peaked white flashes between green flashes

A military airport can be identified at night by the use of a rotating beacon that emits dual peaked white flashes alternating with green flashes. This specific signal is designated for military airfields and helps to differentiate them from civilian airports, which might utilize different lighting patterns. The dual peaked white flashes indicate that the airport is specifically for military use, which is useful for pilots to ensure they are aware of the airspace they are entering. The green flashes indicate that the airport may also be used for general aviation, but the key aspect is the presence of the dual peaked white flashes, which are characteristic of military airports. Understanding these lighting signals is crucial for pilots navigating at night, as they must correctly interpret the various lighting patterns to ensure safety and compliance with aviation regulations.
