QUESTIONUnder 14 CFR part 107, a small unmanned aircraft is one that weighs less than how much on takeoff, including everything on board or otherwise attached to it?

  1. A55 pounds, not counting any attached payload
  2. B100 pounds
  3. C55 pounds
Show the answer and explanation

Correct answer: C. 55 pounds

  • A — incorrect The 55-pound figure is correct, but the definition expressly includes everything on board or otherwise attached, so payload counts.
  • B — incorrect No 100-pound threshold appears in part 107; the definition uses 55 pounds.
  • C — correct § 107.3 defines a small unmanned aircraft as one weighing less than 55 pounds on takeoff, including everything on board or otherwise attached.

BACKGROUND

Title 14 of the Code of Federal Regulations (14 CFR) part 107 governs small unmanned aircraft systems (sUAS). Section 107.3 defines a small unmanned aircraft as an unmanned aircraft weighing less than 55 pounds on takeoff. The definition counts everything that is on board or otherwise attached to the aircraft, so cameras, batteries and any carried load are part of the takeoff weight. This is the loading limit that decides whether an operation falls under part 107 at all.

STUDY TIP

Remember the 55-pound figure and that it is measured at takeoff with all attachments included.

KEY POINTS

  • Small unmanned aircraft: less than 55 pounds on takeoff.
  • Everything on board or attached counts toward that weight.
  • The definition is in § 107.3.
