Editing Stall

== Explanation ==
A stall is a physical phenomenon in fluid dynamics where the [[airfoil]] stops generating [[lift]] when moving through the air at angles above the critical [[angle of attack]]. As airfoils generate lift by the resultant force arising from the airflow around its upper and lower surfaces, the airflow needs to be smooth and continuous for a continuous lift. When the angle of attack increases, the airflow separates from the upper surface and abruptly reduces the lift generated.

== Frequently Asked Questions ==
=== How does an aircraft recover from the stall? ===
A stalled aircraft can be recovered to normal flight be reducing the angle of attack below the critical angle of attack, i.e. by pitching down the aircraft.

=== What is a deep stall? ===
A deep stall is a type of stall where an aircraft's recovery from the stall is highly unlikely due to the loss of controls to pitch down the aircraft. This happens in configurations where a T-tail is involved. When such aircraft enters a stall, the wing at a high angle of attack and the wake from the separated turbulent flow blocks any flow to the tailplane and the elevators. This leaves the elevator ineffective to the pilot's inputs.
