  Chapter 6: Flight Controls › Flight Control Systems › Servo Tabs

  striking the tab counterbalances some of the air pressure against the primary control surface and enables the pilot to move the control more easily and hold the control surface in position. If the linkage between the balance ... small portion of a flight control surface that deploys in such a way that it helps to move the entire flight control surface in the direction that the pilot wishes it to go. A servo tab is a dynamic device…

  Turn stopped Sensation of turning in opposite direction as moving fluid deflects hairs in opposite Inversion Illusion An abrupt change from climb to straight-and-level flight can stimulate the otolith organs enough to create the illusion of tumbling backwards ... illusions that lead to spatial disorientation, false horizon and autokinesis, affect the visual system only. False Horizon A sloping cloud formation, an obscured horizon, an aurora borealis, a dark scene spread with ground lights and stars, and certain geometric patterns…

  trailing edge of the elevator up, reducing the elevator’s AOA. This causes the tail of the aircraft to move down and the nose to move up. In spite of the opposing directional movement of the trim ... that the balancing tab is coupled to the control surface rod so that when the primary control surface is moved in any direction, the tab automatically moves in the opposite direction. The airflow striking the tab counterbalances some…

  unchanged. The total moments, however, do change in relation and proportion to the direction and distance the weight is moved. When weight is moved forward, the total moments decrease; when weight is moved aft, total moments increase. The moment change ... proportional to the amount of weight moved. Since many aircraft have forward and aft baggage compartments, weight may be shifted from one to the other to change the CG. If starting with a known aircraft weight, CG, and total moments…
