What is a stall spin?

What is a stall spin?

A spin is a yaw aggravated stall which results in rotation about the spin axis. In a spin, both wings are in a stalled condition but one wing will be in a deeper stall than the other. The drag is greater on the more deeply stalled wing causing the aircraft to autorotate (yaw) toward that wing.

What is the stall technique?

When entering a stall,you should increase the pitch slowly and smoothly up to a landing pitch attitude, approximately 10° nose up, and hold it there until the stall occurs. The recovery should not be aggressive. If the airplane is loaded properly within its CG range, the nose should naturally lower when a stall occurs.

How do you stop a stall from spinning?

Put another way, don’t stall and the aircraft won’t spin; don’t yaw and a stall will not turn into a spin. To recover from a spin, lower the angle of attack (push forward on the controls) and stop the yaw (apply rudder opposite the direction of spin until rotation stops).

What causes a stall spin?

Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift.

Do you need stall and spin awareness training?

Although the training is intended to emphasize stall and spin awareness and recovery techniques for all pilots, only flight instructor-airplane and flight instructor-glider candidates are required to demonstrate instructional proficiency in spin entry, spins, and spin recovery techniques as a requirement for certification.

What are the statistics on stall and spin?

Pilot Stall Awareness Study, which revealed that stall/spin related accidents accounted for approximately one-quarter of all fatal general aviation accidents. National Transportation Safety Board (NTSB) statistics indicate that most stall/spin accidents result when a pilot is distracted momentarily from the primary task of flying the aircraft.

When do both wings need to be stalled for a spin?

In a spin, one or both wings are in a stalled condition, if both are stalled one wing will be in a deeper stall condition than the other The wing that stalls first will drop, increasing its angle of attack and deepening the stall. Both wings must be stalled for a spin to occur

When does a horse spin after a stall?

If recovery from a stall is not effected in a timely and appropriate manner by reducing the angle of attack, a secondary stall and/or a spin may result. All spins are preceded by a stall on at least part of the wing.
