Power-On Stalls BACK to Index

DescriptionThe airplane is maneuvered to a critically slow airspeed in straight or turning flight in a power-on configuration. The angle of attack is then increased until a stall occurs. ObjectiveTo develop the student’s ability to recognize the aerodynamic indications leading to a stall in power- on situations and to make prompt and effective recoveries with a minimum loss of altitude. Procedure• Complete pre-maneuver checklist. Clear the area. Make radio calls as appropriate. Maintain 2300 RPM and approximately 90 KIAS. Select a prominent outside visual reference in reference to nose of aircraft.• Slow to takeoff speed. Apply carburetor heat and reduce power to 1500 PRM. Increase back pressure on yoke to maintain altitude and slow to (55 KIAS).• Induce stall. As you reach , simultaneously set takeoff (full) power and smoothly and continuously apply back pressure on yok and maintain takeoff pitch attitude until stall occurs. Maintain coordination with the rudders.• Recovery. Upon inducing the stall, immediately release back pressure.• Stop the descent. Gently pull back on the yoke to stop descent and maintain nose attitude level with the horizon to accelerate to or .• Establish a climb. Upon reaching or establish a positive rate of climb.• Return to cruise flight. Once desired altitude is reached, lower nose and allow airspeed to increase. Reduce power to 2300 RPM and trim to relieve control pressure. ACS Standards• Clear the area.• Select an entry altitude that will allow the Task to be completed no lower than 1,500 feet AGL• Establish the takeoff, departure, or cruise configuration, as specified by the evaluator, and maintain coordinated flight throughout the maneuver.• Set power (as assigned by the evaluator) to no less than 65 percent available power.• Transition smoothly from the takeoff or departure attitude to the pitch attitude that will induce a stall.• Maintain a specified heading, ±10° if in straight flight; maintain a specified angle of bank not to exceed 20°, ±10° if in turning flight, while inducing the stall.• Acknowledge cues of the impending stall and then recover promptly after a full stall occurs (private).• Recover at the first indication of a stall or after a full stall has occurred, as specified by the evaluator (commercial).• Execute a stall recovery in accordance with procedures set forth in the POH/AFM.• Configure the airplane as recommended by the manufacturer and accelerate to or .• Return to the altitude, heading, and airspeed specified by the evaluator.
