adjustable stabilizer. Figure 6-19. Spoilers reduce lift and increase drag during descent and landing. Trim Tabs The most common installation on small aircraft is a single trim tab attached to the trailing edge of the elevator. Most trim tabs ... manually operated by a small, vertically mounted control wheel. However, a trim crank may be found in some aircraft. The flight deck control includes a trim tab position indicator. Placing the trim control in the full nose…

horizontal stabilizer, is used to move the nose of the airplane up and down during flight. Trim tabs are small, movable portions of the trailing edge of the control surface. These movable trim tabs, which are controlled from the flight deck, reduce control pressures. Trim tabs may be installed on the ailerons, the rudder, and/or the elevator. Figure 3-9. Weight-shift control aircraft use the shifting of weight for control. A second…

This should be executed concurrent with steps 2 and 3. 5. Heading and Trim ... heading you were already on, which was planned and briefed. Set the heading bug, if installed, to avoid overcontrolling your bank. Maintain coordinated flight so that an unusual attitude will not develop. Try to avoid immediately turning 180°. Turning around…

such as the horizontal stabilizer, are more prone to icing than the wing. With ice accumulations, landing approaches should be made with a minimum wing flap setting (flap extension increases the AOA of the horizontal stabilizer) and with an added ... autopilot should not be used in icing conditions. Continuous use of the autopilot masks trim and handling changes that occur with ice accumulation. Without this control feedback, the pilot may not be aware of ice accumulation building to hazardous…
