Stall speed is affected by which of the following factors?

Stall speed is influenced by weight, load factor, and power because these factors directly relate to how an aircraft generates lift and maintains controlled flight.

Weight is a fundamental factor because as the weight of the aircraft increases, the lift required to maintain level flight also increases. To generate this additional lift, the aircraft must increase the angle of attack or airspeed. Therefore, a heavier aircraft has a higher stall speed compared to a lighter aircraft.

Load factor refers to the increased weight experienced by the aircraft during maneuvers, such as turns. When the load factor increases, the effective weight of the aircraft also increases, thus raising the stall speed. For example, in a banked turn, the load factor increases because the lift must counteract both gravity and centrifugal force, leading to a higher stall speed at which the aircraft will lose lift.

Power can also play a role in stall speed. While it does not directly affect the stall speed in a straight-and-level flight, it impacts the aircraft’s ability to recover from a stall. Increased power allows for potential greater climb rates and controlled flight at lower speeds, which can indirectly influence the conditions under which a stall occurs.
