Power-on stall recoveries are practiced from
straight climbs and climbing turns (15°
to 20° bank) to help the pilot recognize
the potential for an accidental stall during
takeoff, go around, climb, or when trying to
clear an obstacle. Airplanes equipped with flaps
or retractable landing gear should normally
be in the takeoff configuration; however, power-on
stalls should also be practiced with the airplane
in a clean configuration (flaps and gear retracted)
to ensure practice with all possible takeoff
and climb configurations. Power for practicing
the takeoff stall recovery should be maximum
power, although for some airplanes it may be
reduced to a setting that will prevent an excessively
high pitch attitude.
To set up the entry for power-on stalls, establish
the airplane in the takeoff or climb configuration.
Slow the airplane to normal lift-off speed while
continuing to clear the area of other traffic.
Upon reaching the desired speed, set takeoff
power or the recommended climb power for the
power-on stall (often referred to as a departure
stall) while establishing a climb attitude.
The purpose of reducing the airspeed to lift-off
airspeed before the throttle is advanced to
the recommended setting is to avoid an excessively
steep nose-up attitude for a long period before
the airplane stalls.
After establishing the climb attitude, smoothly
raise the nose to increase the AOA, and hold
that attitude until the full stall occurs. As
described in connection with the stall characteristics
discussion, continual adjustments must be made
to aileron pressure, elevator pressure, and
rudder pressure to maintain coordinated flight
while holding the attitude until the full stall
occurs. In most airplanes, as the airspeed decreases
the pilot must move the elevator control progressively
further back while simultaneously adding right
rudder and maintaining the climb attitude until
reaching the full stall.
The pilot must promptly recognize when the stall
has occurred and take action to prevent a prolonged
stalled condition. The pilot should recover
from the stall by immediately reducing the AOA
and applying as much nose-down control input
as required to eliminate the stall warning,
level the wings with ailerons, coordinate with
rudder, and smoothly advance the power as needed.
Since the throttle is already at the climb power
setting, this step may simply mean confirming
the proper power setting.
The final step is to return the airplane to
the desired flightpath (e.g., straight and level
or departure/climb attitude). With sufficient
airspeed and control effectiveness, return the
throttle to the appropriate power setting.
