Surface winds are reported as 10 knots gusting to 25 knots. What is the main concern for a light multirotor drone?
- A.Gusts only matter above 50 knots
- B.A gust spread makes the air smoother near obstacles
- C.The large gust spread signals turbulent, unstable-feeling air that can exceed the aircraft's control authority
Correct answer
C. The large gust spread signals turbulent, unstable-feeling air that can exceed the aircraft's control authority
Why
A wide difference between sustained wind and gusts means the wind speed is changing rapidly. Around buildings and trees this mechanical turbulence can cause sudden attitude and altitude upsets in a light aircraft.
