Loading & PerformanceCâu 85 / 100
How does loading a small UAS close to its maximum takeoff weight affect its performance?
a.It increases endurance and sharpens the response to control inputs
b.It leaves endurance unchanged while improving the rate of climb
c.It shortens the stopping distance and lowers the minimum controllable speed
d.It reduces endurance and slows the rate of climb
Giải thích
Extra weight requires more power just to stay airborne, so the battery drains sooner and the aircraft climbs more slowly. Heavier aircraft are also less responsive, need more distance to stop, and, for fixed-wing designs, fly at a higher minimum controllable speed. None of the benefits listed in the other options occur when weight goes up.
