Power-On Stall and Recovery Slow to lift-off speed, maintain altitude. Set takeoff power, raise nose. When stall occurs, reduce AOA, roll  wings level, and add  power as needed. As flying speed returns, stop descent and establish a climb. Maintain climb airspeed,  raise landing gear and flaps, and trim. Return to the  desired flightpath. Figure 4-8.  Power-on 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. quickly and the critical AOA is exceeded a second time. It  can also occur when the pilot does not sufficiently reduce  the AOA by lowering the pitch attitude or attempts to break  the stall by using power only.  [Figure 4-9] When a secondary stall occurs, the pilot should again perform  the stall recovery procedures by applying nose-down elevator  pressure as required to eliminate the stall warning, level  the wings with ailerons, coordinate with rudder, and adjust  power as needed. When the airplane is no longer in a stalled  condition the pilot can return the airplane to the desired  flightpath. For pilot certification, this is a demonstration-only  maneuver; only flight instructor applicants may be required  to perform it on a practical test. 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.  [Figure 4-8] The objectives of demonstrating an accelerated stall are to  determine the stall characteristics of the airplane, experience  stalls at speeds greater than the +1G stall speed, and develop  the ability to instinctively recover at the onset of such stalls.  This is a maneuver only commercial pilot and flight instructor  applicants may be required to perform or demonstrate on a  practical test. However, all pilots should be familiar with the  situations that can cause an accelerated stall, how to recognize  it, and the appropriate recovery action should one occur.  At the same gross weight, airplane configuration, CG  location, power setting, and environmental conditions,  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.  A secondary stall is so named because it occurs after recovery  from a preceding stall. It is typically caused by abrupt control  inputs or attempting to return to the desired flightpath too  Figure 4-9.  Secondary stall.
