4. Flight Control Systems T-Tail The forces required to raise the nose of a T-tail aircraft are greater than those for a conventional-tail aircraft. The pilot must be aware that the required control forces are greater at slow speeds during takeoffs, landings, or stalls than for similar size aircraft equipped with conventional tails.

6. Flight Control Systems T-Tail When flying at a very high AOA with a low airspeed and an aft CG, the T-tail aircraft may be susceptible to a deep stall. In a deep stall, the airflow over the horizontal tail is blanketed by the disturbed airflow from the wings and fuselage.

10. Flight Control Systems Stabilator Because stabilators pivot around a central hinge point, they are extremely sensitive to control inputs and aerodynamic loads. Antiservo tabs are incorporated on the trailing edge to decrease sensitivity.

12. Flight Control Systems Stabilator They deflect in the same direction as the stabilator. This results in an increase in the force required to move the stabilator, thus making it less prone to pilot- induced overcontrolling.

25. Flight Control Systems Canard The canard design utilizes the concept of two lifting surfaces, the canard functioning as a horizontal stabilizer located in front of the main wings. In effect, the canard is an airfoil similar to the horizontal surface on a conventional aft-tail design.

26. Flight Control Systems Canard The difference is that the canard actually creates lift and holds the nose up, as opposed to the aft-tail design which exerts downward force on the tail to prevent the nose from rotating downward.

27. Flight Control Systems Canard Theoretically, the canard is considered more efficient because using the horizontal surface to help lift the weight of the aircraft should result in less drag for a given amount of lift.

28. Flight Control Systems Rudder The rudder controls movement of the aircraft about its vertical axis. The rudder is a movable surface hinged to a fixed surface, in this case to the vertical stabilizer.

29. Flight Control Systems Rudder By pushing the left pedal, the rudder moves left. This creates a sideward lift that moves the tail to the right and yaws the nose of the airplane to the left.

30. Flight Control Systems Rudder Rudder effectiveness increases with speed; therefore, large deflections at low speeds and small deflections at high speeds may be required to provide the desired reaction.

31. Flight Control Systems V-Tail The V-tail design utilizes two slanted tail surfaces to perform the same functions as the surfaces of a conventional elevator and rudder configuration. The fixed surfaces act as both horizontal and vertical stabilizers.

32. Flight Control Systems V-Tail The movable surfaces, which are usually called ruddervators, are connected through a special linkage that allows the control wheel to move both surfaces simultaneously.

33. Flight Control Systems V-Tail On the other hand, displacement of the rudder pedals moves the surfaces differentially, thereby providing directional control. A control mixing mechanism moves each surface the appropriate amount.

34. Flight Control Systems V-Tail The V-tail design is more susceptible to Dutch roll tendencies than a conventional tail, and total reduction in drag is minimal.

35. Flight Control Systems Secondary Flight Controls Secondary flight control systems: Consist of wing flaps, leading edge devices, spoilers, and trim systems.

36. Secondary Flight Controls Flaps The most common high-lift devices used on aircraft are attached to the trailing edge of the wing, increase both lift and induced drag for any given AOA.

37. Secondary Flight Controls Flaps Flaps allow a compromise between high cruising speed and low landing speed, because they may be extended when needed, and retracted into the wing’s structure when not needed.

38. Secondary Flight Controls Flaps There are four common types of flaps: plain, split, slotted, and Fowler flaps.

39. Secondary Flight Controls Flaps The plain flap is the simplest of the four types.

40. Secondary Flight Controls Flaps It increases the airfoil camber, resulting in a significant increase in the coefficient of lift (CL) at a given AOA. At the same time, it greatly increases drag and moves the center of pressure (CP) aft on the airfoil, resulting in a nose- down pitching moment.

41. Secondary Flight Controls Flaps The split flap is deflected from the lower surface of the airfoil and produces a slightly greater increase in lift than the plain flap. When fully extended, both plain and split flaps produce high drag with little additional lift.

42. Secondary Flight Controls Flaps The most popular flap on aircraft today is the slotted flap. Slotted flaps increase the lift coefficient significantly more than plain or split flaps.

43. Secondary Flight Controls Flaps Fowler flaps are a type of slotted flap. This flap design not only changes the camber of the wing, it also increases the wing area. Instead of rotating down on a hinge, it slides backwards on tracks.
