- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Elevator Trim Stall
Elevator Trim Stall The elevator trim stall demonstration shows what can happen when the pilot applies full power for a go-around without maintaining positive control of the airplane. [Figure 5-14] This is a demonstration-only maneuver; only flight ... perform it on a practical test. However, all pilots should be familiar with the situations that can cause an elevator trim stall, recognize its development, and take appropriate action to prevent it. Figure 5-14. Elevator trim stall. This situation…
- 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 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 › 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 ... 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 may occur after any stall when the pilot does…
- Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Stall Recognition
Indications of a full stall are typically that an uncommanded nose down pitch cannot be readily arrested, and may be accompanied by an uncommanded rolling motion. For airplanes equipped with stick pushers, their activation is also an indicator ... full stall. Although it depends on the degree to which a stall has progressed, some loss of altitude is expected during recovery. The longer it takes for the pilot to recognize an impending stall, the more likely it is that…
