Why does holding position in a steady strong wind consume more battery than hovering in calm air?
- A.The aircraft must continuously produce extra thrust tilted against the wind
- B.Wind cools the motors so they draw more current
- C.GPS position hold uses the main flight battery for calculations
Correct answer
A. The aircraft must continuously produce extra thrust tilted against the wind
Why
To stay in place, the aircraft leans into the wind and the motors sustain higher output the entire time. Endurance falls even though the aircraft is not traveling anywhere.
