The air acceleration over the wing

of an aircraft, generating lift, can be increased by tilting the wing up which

is normally achieved by pitching the nose of the aircraft up which increases

the angle of attack on the wing. A basic wing platform can only generate lift

to a certain angle of attack. Beyond the critical angle of attack, the wing

enters a stall.

The wing of an aircraft generates

lift by accumulating air outside of it. This lift can be increased by tilting

the wing up which is normally achieved by pitching the nose of the aircraft up

which increases the angle of attack (the angle between the airfoil chord and

relative airflow) on the wing. A basic wing platform can only generate lift to

a certain angle of attack. Beyond this angle of attack, called the critical

angle of attack, the wing enters a stall as the airflow separates from the

upper surface of the wing.  The high lift

devices can be used to delay this stall and let the wing reach a high angle of

attack.

The wing of an aircraft generates

lift by accelerating air outside of it. This lift can be increased by melting

the wing up which is normally achieved by  the increase of  the angle between the airfoil chord and

relative airflow on the wing. A basic wing platform can only generate lift to a

certain angle of attack. Beyond this angle of attack, called the critical angle

of attack, the wing enters a stall as the airflow separates from the upper

surface of the tail.  The high lift devices

can be used to put off this stall and let the tail reach a high angle of

attack.
