Power-on stalls
What is the proper recovery with regards to power? After the stall occurs, I have always reduced power to idle to recover and then added full power to establish climb. Should I maintain full throttle throughout the stall and the recovery? Your thoughts....

If you stalled after takeoff, would you reduce power? Not to sound like a jerk, but a lot of the time students don't read the airplane flying handbook and assume that everything they were instructed upon is correct, then an examiner or inspector says it's wrong and shows them why/where. Specifically go read the "power on stalls" section. I guarantee for the most part that the examiner will be expecting you to do what is in the AFH. Sometimes your "takeoff power" is not "full power" as I recall though, depends on the aircraft.

Definitely do not reduce power at the break, you are removing lift from the wings from the prop wash by doing that, which could worsen a sloppy, uncoordinated stall. I agree, read the section on this in Airplane Flying Handbook, every student needs copy and should consult it often. Ask questions as you are doing.

Any stall recovery should primarily be concerned with
1. Exit the stall immediately
2. Fix the condition that caused the stall
3. Stop altitude loss and some teach climb 100 feet from point of stall and then level off
Remember a stall is caused by excessive angle of attack and thus loss of lift situation.

Pulling the power out will further destabilize the airplane, as you'll lose the nose-down force of the propwash going over the rear horizontal stabilizers, making it even more difficult to recover from the stall.
The first and foremost thing to do is relieve the angle of attack, and simultaneously apply maximum power if not already applied.

also remember that things in training are supposed to replicate/simulate things in real life. Power On stall is to show you want can happen if you are on a takeoff climbout and get distracted and stall the airplane. Power will already be up. So the last thing you want to do is pull power.

I can't agree with the above posts any more. I figured the procedure was wrong after looking over the Airplane Flying Handbook, thus the reason for this post and to confirm my suspicion. Have flown with several CFI's and DPEs without any opposition. Thanks everyone.

Full power and minimum altitude loss!
At the university I'm currently at when people come in with their private they have to go through a standardization class to get used to the schools plane and procedures before they can go into instrument. Anyways, I just had a student that had gotten his private less than a month ago that had a habit of reducing the power to idle on power on stalls, and he told me his old instructor taught him that way. I figured he had forgotten the proper recovery technique (even though its only been a couple weeks since he passed his checkride) and he was just doing the old 'everything's my instructor's fault!' game. But maybe there actually are some CFI's out there teaching this?!?
