FAA Part 107 Remote Pilot (UAG)RegulationsMedium
A hobbyist builds a fixed-wing aircraft that weighs 54 pounds empty. After adding a 3-pound camera payload and battery pack, the total takeoff weight is 57 pounds. Can this aircraft be operated under Part 107?
- AYes, as long as the pilot obtains a special waiver for weight only
- BNo, because fixed-wing aircraft are never eligible under Part 107 regardless of weight
- CYes, because the airframe alone weighs less than 55 pounds
- DNo, because the total weight including everything on board at takeoff exceeds the 55-pound small UAS limit
Show answer & explanationAnswer & explanation
Correct answer: D. No, because the total weight including everything on board at takeoff exceeds the 55-pound small UAS limit
Part 107 defines a small unmanned aircraft as one weighing less than 55 pounds at takeoff, including everything on board or attached. Since the total takeoff weight here is 57 pounds, it exceeds the small UAS threshold and cannot operate under Part 107 without a waiver process for larger aircraft not covered by standard sUAS rules.
Why the other options are wrong
- A. Incorrect — Part 107 waivers address specific operating rules, not the fundamental weight-based sUAS definition.
- B. Incorrect — fixed-wing aircraft can qualify under Part 107 if under the weight threshold.
- C. Incorrect — the weight limit applies to total takeoff weight, not just the airframe.
Small UAS Weight Threshold
Part 107 applies only to small unmanned aircraft weighing less than 55 pounds at takeoff, including everything on board or attached at the time of flight.
- Threshold: less than 55 lbs at takeoff
- Includes payload, batteries, and attachments
- Heavier aircraft require different certification pathways
- Distinct from the 0.55 lb registration threshold
Memory trick: '55 is the ceiling, everything counts—empty or filled.'
