Try it on landing, full flaps and gear down, fly as slowly as possible, you'll find as you get slower there comes a point where you have to add power in order to fly slower. This is the back end of the drag curve. Fly even more slowly still and keep adding power until it stalls. See what happens.
Not something you want to do in a real aircraft.
You have to raise the nose along with adding the power to get slower. If you don't raise the nose, you WILL get faster. Basically this is how you enter the proper attitude for flying "flats". But, you will get to a point where even at full power, you will exceed the stall angle of attack of the plane, and will start falling out of the sky. The angle of attack is a set number, but airspeeds will vary.
The military practice stalls all the time, and I think they are in civilian training also??? If you don't know how your aircraft reacts when it stalls, you won't know how to counteract or recover from it.
Stalling a plane in a controlled environment is actually rather benign. These would be for example a wings level stall where the pilot maintains an altitude, while pulling the throttle back to idle. As the airspeed decreases, the pilot tries to maintain zero vsi until the plane stalls. Recovery is usually as simple as releasing the back pressure on the stick/yoke and letting the nose fall to build airspeed.
An approach turn stall is pretty much the same, except as the name implies, you are attempting a turn on to final. Here instead of using power to maintain altitude during the approach turn, you keep pulling back on the stick to raise the nose. As you do so, the airspeed bleeds off until the plane stalls. Recovery here is also different in that you have to used coordinated stick/rudder to get wings level and also go full throttle (you are simulating being close to the ground).
Accelerated stalls are practiced by the military and not so much in a civilian plane, unless it is a high performance aircraft. These can easily lead into a spin if you are caught by suprise, or don't know how to handle them.
Wow, didn't mean to go on for this long, but not too often I get to talk about something I actually know a little about and have practiced:D
