FAA Part 107 Remote Pilot (UAG)RegulationsMedium
A remote pilot plans to continue an sUAS operation into civil twilight, beginning about 20 minutes after official sunset. According to 14 CFR Part 107, what must be installed on the aircraft to legally continue this operation?
- AA supplemental infrared camera to detect nearby aircraft
- BA steady white position light visible for at least 1 statute mile
- CAnti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision hazard
- DAn ADS-B Out transponder broadcasting position
Show answer & explanationAnswer & explanation
Correct answer: C. Anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision hazard
14 CFR 107.29 allows civil twilight operations (30 minutes before sunrise to 30 minutes after sunset) only if the sUAS has anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision hazard. ADS-B, infrared cameras, and steady position lights are not the required equipment under this rule.
Why the other options are wrong
- A. Infrared cameras are not a regulatory lighting requirement.
- B. The requirement specifies a flashing anti-collision light, not a steady position light, and a 3-mile visibility distance, not 1 mile.
- D. ADS-B Out is not required equipment for sUAS under Part 107.
Civil Twilight Operations (107.29)
Small UAS may operate during civil twilight (30 min before sunrise to 30 min after sunset) if equipped with anti-collision lighting visible for at least 3 statute miles.
- Daylight operations require no special lighting
- Civil twilight extends the operating window by 30 minutes on each end
- Anti-collision light must flash at a rate sufficient to avoid collision
Memory trick: 3 miles of blink before you sink into darkness.
