In which conditions is icing on a small drone most likely to occur?
- A.Flight in dry, clear air well above freezing
- B.Flight in visible moisture, such as cloud or freezing rain, with temperatures at or below freezing
- C.Flight on a warm afternoon with low humidity
Correct answer
B. Flight in visible moisture, such as cloud or freezing rain, with temperatures at or below freezing
Why
Icing requires both moisture that can strike the aircraft and temperatures cold enough to freeze it on contact. Clouds, fog, and freezing precipitation at near-freezing temperatures are the classic setup.
