Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Accelerated Stalls
Accelerated Stalls While pilots may understand the cause of an accelerated stall, it takes training to experience how these stalls develop and occur. 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…

Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Full Stalls, Power-Off
Full Stalls, Power-Off The practice of power-off stalls is usually performed with normal landing approach conditions to simulate an accidental stall occurring during approach to landing. However, power-off stalls should be practiced at all flap settings ... ensure familiarity with handling arising from mechanical failures, icing, or other abnormal situations. Airspeed in excess of the normal approach speed should not be carried into a stall entry since it could result in an abnormally nose-high attitude…

Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Full Stalls, Power-On
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 ... pilot should 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 should be made to aileron pressure, elevator pressure, and rudder…

Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Stalling Speeds
Load Factors and Stalling Speeds Any aircraft, within the limits of its structure, may be stalled at any airspeed. When a sufficiently high AOA is imposed, the smooth flow of air over an airfoil breaks up and separates, producing ... abrupt change of flight characteristics and a sudden loss of lift, which results in a stall. A study of this effect has revealed that an aircraft’s stalling speed increases in proportion to the square root of the load factor…
