Question 3
Domain 4: FAA Part 107 RegulationsUnder Part 107, a small unmanned aircraft must weigh less than:
Correct answer: C
Explanation
Under 14 CFR Part 107, a small unmanned aircraft is defined as an unmanned aircraft weighing "less than 55 pounds on takeoff, including everything that is on board or otherwise attached to the aircraft." That weight limit is the rule that makes "55 pounds" the right answer.
Why each option is right or wrong
A. 25 pounds
B. 35 pounds
C. 55 pounds
14 CFR § 107.3 defines a small unmanned aircraft as one that weighs less than 55 pounds on takeoff, including everything onboard or attached. The 55-pound threshold is the regulatory cutoff under Part 107; at 55 pounds or more, the aircraft falls outside the small UAS category and Part 107’s operating rules do not apply in the same way.
D. 100 pounds
