Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Secondary Stall
Secondary Stall A secondary stall is so named because it occurs after recovery from a preceding stall. A normal recovery usually involves pointing the nose of the airplane toward the ground. However, if a stall should occur at low altitude ... abruptly. This reaction is amplified as proximity to the ground increases. To demonstrate how this occurs at altitude, the pilot makes an abrupt recovery after one stall and exceeds the critical AOA a second time. Note that this stall…

CHAPTER 2. FLIGHT TRAINING: STALLS › 200. STALL TRAINING › f. Stalls During Go-Arounds
Cross Controlled Stalls in Gliding Turns. Perform stalls in gliding turns to simulate turns from base to final. Perform the stalls from a properly coordinated turn, a slipping turn, and a skidding turn. Explain the difference between slipping and skidding ... turns. Explain the ball indicator position in each turn and the aircraft behavior in each of the stalls. e. Power-Off (Approach-To-Landing) Stalls (1) Have the student perform a full-flap, gear-extended, power-off stall with…

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
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…

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…
