FAA Part 107 Remote Pilot (UAG)OperationsEasy
A remote pilot plans a sUAS operation that will extend past evening civil twilight. Per 14 CFR Part 107, the aircraft's anti-collision lighting must be visible for a minimum of how many statute miles?
- A2 statute miles
- B1 statute mile
- C5 statute miles
- D3 statute miles
Show answer & explanationAnswer & explanation
Correct answer: D. 3 statute miles
Per 14 CFR 107.29, sUAS operating during periods of reduced visibility (including night) must be equipped with anti-collision lighting visible for at least 3 statute miles.
Why the other options are wrong
- A. Also below the required 3 statute mile minimum.
- B. Too short a distance to meet the regulatory minimum.
- C. Exceeds the actual regulatory requirement.
Anti-Collision Light Visibility (107.29)
For night or twilight operations, sUAS must have anti-collision lighting visible for at least 3 statute miles, with an exception allowed for reduced distance if it still meets see-and-avoid needs.
- Required for night and civil twilight operations
- 3 statute mile minimum visibility
- Waiver can allow reduced distance if justified
Memory trick: '3 for the dark' — three statute miles keeps your drone visible at night.
