FAA Part 107 Remote Pilot (UAG)OperationsMedium
A remote pilot in command is preparing to fly a multi-rotor sUAS that has a maximum certified takeoff weight of 54.6 pounds. The aircraft's empty weight is 48 pounds, and the pilot wants to attach a camera payload weighing 6 pounds and a battery pack weighing 2 pounds. What must the remote pilot conclude?
- AThe configuration is acceptable as long as the flight remains within visual line of sight
- BThe 55-pound limit only applies to the empty weight of the aircraft, so this configuration is legal
- CThe configuration exceeds the aircraft's structural limit and also exceeds the 55-pound Part 107 weight limit, so it cannot be flown as configured
- DThe configuration is acceptable because the total weight of 56 pounds is under the 55-pound Part 107 limit
Show answer & explanationAnswer & explanation
Correct answer: C. The configuration exceeds the aircraft's structural limit and also exceeds the 55-pound Part 107 weight limit, so it cannot be flown as configured
Total weight = 48 lb (empty) + 6 lb (camera) + 2 lb (battery) = 56 lb. This exceeds both the aircraft's stated maximum certified takeoff weight of 54.6 lb and the Part 107 maximum allowable takeoff weight of 55 lb (including everything on board), so the aircraft cannot be legally or safely flown in this configuration without removing weight.
Why the other options are wrong
- A. VLOS compliance does not override weight limitations.
- B. The 55-pound limit applies to total takeoff weight, including all payload and attachments, not just empty weight.
- D. 56 pounds is over 55 pounds, not under it — this is a math error.
Maximum Takeoff Weight (Part 107)
Part 107 sUAS, including everything on board or attached, must weigh less than 55 lbs at takeoff unless operating under an exemption.
- 55 lb limit includes payload and any external attachments
- Total weight = empty weight + payload + accessory weight
- Exceeding manufacturer's structural limit is also unsafe even if under 55 lb
- Weight and balance affects flight characteristics and control
Memory trick: 55 is the ceiling — add it all before you fly
