Why pilots practice stalls

Content: Various factors including the weight of the aircraft, flaps, and icing can change the angle of attack the aircraft stalls at. For the rest of us
A stall happens when the wing no longer creates lift. This happens when the speed of the air going over the wing decreases too much. Basically, this is why the advice one mother gave her son during World War I, 'Fly low and slow, I don't want you to get hurt!' makes very little sense aerodynamically speaking. Why pilots practice stalls
Pilots practice stalls to learn the warning signs that they are entering a stall, and to practice recovering from a stall should they ever end up in one. Also, as brinky stated in a comment to this answer: While in flight training or when moving to a different airframe,  pilots practice putting the aircraft in a stall and then recovering  from it to also develop "muscle-type" memory, because stalls are  probably the single most unsettling and unpredictable behavior that  all aircraft share, and different airframes may react very differently  to stalls. Stalls are unforgiving and must be rectified promptly, due  to rapid altitude loss. Share

The stalls that pilots practice are aerodynamic stalls not engine stalls.
