What factors are considered when calculating stall speed?

Stall speed is primarily influenced by factors related to the aircraft's performance and design, which include aircraft weight, load factor, and wing configuration.

When it comes to aircraft weight, a heavier aircraft requires a higher speed to maintain lift. This is because the lift generated by the wings must counteract the weight of the aircraft; therefore, as weight increases, the stall speed also increases.

The load factor, which is the amount of load felt by the aircraft in flight due to maneuvering or banking, directly impacts stall speed as well. If an aircraft is subjected to greater load factors, the stall speed will increase because the wings must produce more lift to counteract the increased forces acting on the airplane.

Wing configuration, such as flaps and slats, can also significantly affect stall speed. Deploying flaps, for example, changes the airflow over the wings and increases lift at lower speeds, thereby reducing stall speed. Conversely, flying with a clean configuration (no flaps or slats) typically presents a higher stall speed.

Thus, the combination of weight, load factor, and wing configuration provides a comprehensive view of the dynamic conditions that influence stall speed during flight, making this the correct focus when calculating stall speed.
