At least one wing must be stalled for a spin to occur. The other wing rises, decreasing its angle of attack, and the aircraft yaws towards the more deeply stalled wing. The difference in lift between the two wings causes the aircraft to roll, and the difference in drag causes the aircraft to continue yawing.
Any disturbance of the angle of attack on one wing will cause the whole wing to roll spontaneously and continuously. [1] [3] When the angle of attack on the wing of an aircraft reaches the stalling angle the aircraft is at risk of autorotation. This will eventually develop into a spin if the pilot does not take corrective action.
Graveyard spirals are the result of several sensory illusions in aviation which may occur in actual or simulated IMC, when the pilot experiences spatial disorientation and loses awareness of the aircraft's attitude. The pilot loses the ability to judge the orientation of their aircraft due to the brain's misperception of spatial cues.
A spin is more complex, involving intentionally stalling a single wing, causing the plane to descend spiraling around its yaw axis in a corkscrew motion. A hammerhead (also known as a stall turn ) is performed by pulling the aircraft up until it is pointing straight up (much like the beginning of a loop), but the pilot continues to fly straight ...
Loss of control causes aircraft to depart from normal flight and possibly reach altitudes or encounter situations from which it can be difficult or impossible to recover, such as a stall or a spin. [1]
The airplane is designed to be able to withstand a bird impact. However, sometimes the circumstance is more than what the engine is designed to ingest, or it causes some particular damage.
If the aviator then ends the turn or spin and returns to level flight, the continued motion of the fluid will cause a sensation the aircraft is turning or spinning in the opposite direction, and the pilot may re-enter the original turn or spin inadvertently; the aviator may not recognize the illusion before the aircraft loses too much altitude ...
