power settings, this angle will need to be considerably nose high. The
break of a power-on stall is preceded by a significant amount of
airframe buffeting, which provides a clear 3–5 kt. warning period
before the actual onset of the stall. Before attempting a full power-on
stall, fly the aircraft into this buffet and become familiar with its feel.
Holding the nose-high attitude through the buffet will eventually cause
the stall to break. The nose will drop decisively, although neither
particularly abruptly nor very far. One wing or the other (typically the
left wing) is likely to drop, but as with the nose drop, this occurs fairly
slowly.
To recover from a power-on stall, release the back pressure on the stick
to reduce the angle of attack and apply full power. If a wing has
dropped, simultaneously apply “top” rudder—that is, rudder opposite
the dropped wing. In any but the most extreme nose-high stalls, it is
unnecessary to push the nose down actively to regain flying speed;
mere relaxation of back pressure will suffice to arrest the stall with
virtually no altitude loss.

As in power-off stalls, the Sportsman retains control authority
in all three axes throughout a power-on stall. This makes it
possible to use aileron rather than rudder to pick up a low wing
during a power-on stall. Although this technique is effective in
the Sportsman, we discourage making a habit of it, as it will be
ineffective or worse in many other aircraft. Use of rudder only
to arrest wing drop during a stall is a good, standard practice
to cultivate regardless of the aircraft being flown.
