Why does a headwind on the return leg deserve special attention in battery planning?
- A.A headwind charges the battery through the motors
- B.Groundspeed drops, so the return takes longer and uses significantly more energy
- C.A headwind has no effect because airspeed stays the same
Correct answer
B. Groundspeed drops, so the return takes longer and uses significantly more energy
Why
Against a headwind the aircraft covers ground slowly while the motors work hard, stretching the return in both time and energy. Pilots should turn for home earlier and keep extra reserve on windy days.
