A remote pilot's drone is rated by the manufacturer for a maximum operating wind speed of 23 knots. The surface observation at the flight site reports 18 knots gusting to 27 knots. What is the correct pre-flight decision?
Why →
The manufacturer's rated wind speed is the maximum value the aircraft can safely handle, not an average. A gust of 27 knots exceeds that limit and can cause loss of control regardless of the average wind. Additionally, winds aloft at 200 to 400 feet AGL are typically 30 to 50 percent stronger than surface readings. The PIC's responsibility under § 107.49 includes matching aircraft capability to environmental conditions as observed, not averaged.The trap →
Choice B averages the wind, which is not how structural and control limits work. Choice C assumes surface reports reflect altitude conditions, which is the opposite of what terrain and thermal effects usually produce.SOURCE → 14 CFR § 107.49; FAA-G-8082-22, Weather and PerformanceCHECKED APR 21ACS V.C.K1HARD
