RegulationsQuestion 29 of 100

Midway through a mapping flight the remote pilot notices one motor running unusually hot and hears an intermittent buzzing from that arm. What does Part 107 require?

a.Continue the mission but reduce groundspeed to 30 knots for the remainder
b.Discontinue the flight, because the aircraft is no longer in a condition for safe operation
c.Continue the mission and note the discrepancy in a post-flight report
d.Continue only if a visual observer confirms the aircraft still appears stable

Explanation

Correct answer: discontinue the flight. Section 107.15 requires the RPIC to verify before flight that the sUAS is in a condition for safe operation and to discontinue the flight when a condition arises that would endanger persons or property. Slowing down, logging the problem later, or relying on an observer does not correct an unairworthy condition.
