FAA Part 107 Remote Pilot (UAG)Airspace and Operating RequirementsHard
A remote pilot wants to operate a small UAS during civil twilight, 20 minutes after official sunset. What equipment requirement must be met to legally conduct this operation under Part 107?
- AThe sUAS must display anti-collision lighting visible for at least 3 statute miles
- BNo additional lighting is required as long as the operation ends by sunset plus 30 minutes
- CThe remote pilot in command must wear a headlamp visible to other airspace users
- DThe sUAS must be equipped with a strobe light visible for at least 1 statute mile
Show answer & explanationAnswer & explanation
Correct answer: A. The sUAS must display anti-collision lighting visible for at least 3 statute miles
Part 107 allows civil twilight operations (30 minutes before official sunrise to 30 minutes after official sunset) provided the sUAS has lighted anti-collision lighting visible for at least 3 statute miles that has a flash rate sufficient to avoid a collision hazard.
Why the other options are wrong
- B. Lighting is still required during civil twilight even though the operation is legal; visibility alone doesn't remove the equipment requirement.
- C. A headlamp on the pilot does not satisfy the anti-collision lighting requirement for the aircraft.
- D. 1 statute mile visibility does not meet the regulatory minimum of 3 statute miles.
Civil Twilight Lighting Requirement
sUAS operations during civil twilight require anti-collision lighting visible for at least 3 statute miles.
- Civil twilight: 30 min before sunrise and 30 min after sunset
- Anti-collision light must have a flash rate sufficient to avoid collision hazard
- Daylight-only rule was amended to permit twilight ops with lighting
Memory trick: 'Twilight needs a light seen for 3' — 3 statute miles visibility.
