- Chapter 6: Flight Controls › Flight Control Systems › T-Tail
When the trim tab becomes ineffective, the down spring drives the elevator to a nose-down position. The nose of the aircraft lowers, speed builds up, and a stall is prevented. [Figure 6-12] The elevator must also have sufficient ... with the reduced landing speed, makes the elevator less effective. Figure 6-11. Aircraft with a T-tail design at a high AOA and an aft CG. Figure 6-12. When the aerodynamic efficiency of the horizontal tail surface…

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 3: Basic Flight Maneuvers › Trim Control
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…
- 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…
