Drone Pilot Practice Exam

Question: 1 / 400

What effect does increased load factor have on a UAS?

Stalls at lower airspeeds

Stalls at higher airspeeds

Increased load factor refers to the ratio of the lift generated by the aircraft to the weight of the aircraft and can directly impact the stall speed. As the load factor increases, the stall speed of a UAS (Unmanned Aircraft System) also increases. This means that the UAS will require a higher airspeed to maintain controlled flight and avoid a stall.

When a UAS operates under higher load factors—such as during sharp turns or rapid climbs—the aerodynamic forces acting on it are magnified. Therefore, at a higher load factor, the aircraft must fly at a faster speed to generate the necessary lift to support the increased weight. Thus, pilots must be aware that they could stall at higher airspeeds if they exceed the performance limits of the UAS. Understanding this relationship is crucial for safe flight operations, particularly in dynamic environments.
