What are common causes of a spin in an aircraft?

A spin is a specific type of aerodynamic stall characterized by a combination of a stalled wing and a yawing motion. The correct cause of a spin is stalling the aircraft while uncoordinated. This means that if the pilot does not properly manage the aircraft's control inputs—specifically the use of ailerons and rudder—the aircraft can enter a spin.

When an aircraft stalls, the wings lose lift. If one wing is more stalled than the other (for instance, due to improper use of the ailerons, resulting in uncoordinated flight), the difference in lift can cause the aircraft to yaw towards the more stalled wing, leading to a spin. Understanding this interaction between stall and yaw is crucial in recognizing how spins occur in flight.

While other factors listed can influence aircraft performance, they do not directly relate to the initiation of a spin as a function of uncoordinated flight during a stall. For example, while excessive speed during landing and improper weight distribution can affect the aircraft's handling characteristics, they do not inherently lead to a spin in the same way that an uncoordinated stall does. Overuse of the rudder can lead to adverse yaw but is not the primary cause of a spin in the
