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?

  1. A2 statute miles
  2. B1 statute mile
  3. C5 statute miles
  4. D3 statute miles
Show answer & 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.
