  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…

  This loss of power will result in a VMC lower than the stall speed at higher altitudes. (VMC is the minimum control speed with the critical engine inoperative). Also, some airplanes have such an effective rudder that even ... level VMC is lower than stall speed. For these airplanes, demonstrating loss of directional control may be safely conducted by limiting rudder travel to simulate maximum rudder available. Limiting rudder travel should be accomplished well above the power-off stall…

  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…

  Trim Control Trim control surfaces are required to offset any constant flight control pressure inputs provided by the pilot. For example, elevator trim is a typical trim in light GA airplanes and is used to null the pressure exerted ... Figure 3-9] This provides an opportunity for the pilot to divert attention to other tasks. Figure 3-9. Elevator trim is used in airplanes to null the pressure exerted by the pilot on the pitch flight control. Because…

  tail, the position of the engines (such as being mounted on the tail) may increase the susceptibility of deep stall events. Therefore a deep stall may be more prevalent on transport versus general aviation aircraft. Since flight at a high ... dangerous, many aircraft have systems to compensate for this situation. The systems range from control stops to elevator down springs. On transport category jets, stick pushers are commonly used. An elevator down spring assists in lowering the nose…

  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…
