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 3. FLIGHT TRAINING: SPINS › 300. SPIN TRAINING › a. Spin training must be accomplished in an aircraft that is approved for spins
Spin training must be accomplished in an aircraft that is approved for spins. Before practicing intentional spins, the AFM or POH should be consulted for the proper entry and recovery techniques. b. The training should begin by practicing both power ... power-off stalls to familiarize the applicant with the aircraft's stall characteristics. Spin avoidance, incipient spins, actual spin entry, spin, and spin recovery techniques should be practiced from an altitude above 3,500 feet AGL. c. Spin avoidance training…

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…

CHAPTER 1. GROUND TRAINING: STALL AND SPIN AWARENESS › 104. TYPES OF STALLS
TYPES OF STALLS. Stalls can be practiced both with and without power. Stalls should be practiced to familiarize the student with the aircraft’s particular stall characteristics without putting the aircraft into a potentially dangerous condition. In multiengine airplanes, single ... engine stalls must be avoided. Descriptions of some different types of stalls follows: a. Power-off stalls (also known as approach-to-landing stalls) are practiced to simulate normal approach-to-landing conditions and configuration. Many stall/spin accidents have occurred…

Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls
Stalls A stall is an aerodynamic condition which occurs when smooth airflow over the airplane’s wings is disrupted, resulting in loss of lift. Specifically, a stall occurs when the AOA—the angle between the chord line of the wing ... attitude, and at any power setting. [Figure 5-8] Figure 5-8. Critical angle of attack and stall. For these reasons, it is important to understand factors and situations that can lead to a stall, and develop proficiency in stall…
