Newbie Qs on stalls and spins

No, you have to take another look at it. NO normal landing involves a stall.

If a man gets into a fight 3,000 miles away from home, he *had* to have
been looking for it.

Well, from what I understand, the generally accepted aviation definition of
a "stall" is when a lifting portion of the aircraft is no longer lifting.

Given that, if the lifting parts never stalled the aircraft would never stop
flying.

No, the definition of an aerodynamic stall is when the airflow passing over the
upper surface of the wing separates from it and produces a burble. Lift is
certainly reduced when this occurs, but the absence of lift by itself is not the
definition of a stall.

Reference: "Flight Theory for Pilots", Charles Dole, 4th ed.

stall -- airflow separation of the boundary layer from a lifting surface.
characterized by a loss of life and an increase in drag. two types of
stall of interest tot he non-jet pilot: slow speed and accelerated.

Proofread you work or you might scare hell out of somebody.

Airliners do not land like that. They fly gently on to the runway and
then the lift is killed by lowering the nose. The lift is reduced but
the angle of attack for a stall is not reached.
