QUESTIONA remote pilot in command plans to conduct a Category 2 operation over people at night. Under § 107.29, what anti-collision lighting must the small unmanned aircraft have?

  1. ALighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision
  2. BLighting visible for at least 5 statute miles, with a flash rate sufficient to avoid any collision
  3. CSteady (non-flashing) lighting visible for at least 1 statute mile in all directions
Show the answer and explanation

Correct answer: A. Lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision

  • A — correct § 107.29(a)(2) requires lighted anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision for any night operation, including one over people.
  • B — incorrect The regulation sets the visibility distance at 3 statute miles, not 5.
  • C — incorrect § 107.29 requires a flash rate sufficient to avoid a collision and a visibility of at least 3 statute miles; steady lighting visible for 1 mile does not meet either requirement.

BACKGROUND

Operations over people at night must satisfy both subpart D and the night rule in § 107.29. Under § 107.29(a), no person may operate a small unmanned aircraft system at night unless the remote pilot in command has completed an initial knowledge test or training under § 107.65 after April 6, 2021, and the aircraft has lighted anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision. The remote pilot in command may reduce the intensity of the lighting in the interest of safety but may not extinguish it. The same lighting requirement applies during civil twilight under § 107.29(b).

STUDY TIP

Remember the pair of night prerequisites: current knowledge test or training after April 6, 2021, and anti-collision lighting visible for 3 statute miles that may be dimmed but never turned off.

KEY POINTS

  • Night operations require anti-collision lighting visible for at least 3 statute miles.
  • The lighting must flash at a rate sufficient to avoid a collision.
  • The remote pilot in command may reduce the intensity but may not extinguish the lighting.
