  Chapter 10: Advanced Flight Maneuvers › Rapid Deceleration or Quick Stop › Technique

  Technique The maneuver requires a high degree of coordination of all controls. It is practiced at a height that permits a safe clearance between the tail rotor and the surface throughout the maneuver, especially at the point where the pitch ... attitude is highest. The height at completion should be no higher than the maximum safe hovering height prescribed by that particular helicopter’s manufacturer. In selecting a height at which to begin the maneuver, take into account the overall length…

  example, the horizontal tail surfaces may be attached near the lower part of the vertical stabilizer, at the midpoint, or at the high point, as in the T-tail design. Figure 6-10. The elevator is the primary control ... changing the pitch attitude of an aircraft. T-Tail In a T-tail configuration, the elevator is above most of the effects of downwash from the propeller, as well as airflow around the fuselage and/or wings during normal flight conditions…

  Chapter 9: Basic Flight Maneuvers › Hovering—Forward Flight › Technique

  Common Errors Failing to maintain a slow, constant rate of turn. 2. Failing to maintain position over the reference point. 3. Failing to maintain rpm within normal range. 4. Failing to maintain constant altitude. 5. Failing to use the antitorque ... helicopter to a specific location, and it may begin from a stationary hover. During the maneuver, constant groundspeed, altitude, and heading should be maintained. Technique Before starting, pick out two references directly in front and in line with the helicopter…

  Exaggerated movement of the cyclic, resulting in erratic movement over the surface. Figure 9-7. To maintain a straight ground track, use two reference points in line and at some distance in front of the helicopter. Failure to use proper ... antitorque pedal control, resulting in excessive heading change. 3. Failure to maintain desired hovering height. 4. Failure to maintain proper rpm. 5. Failure to maintain alignment with direction of travel. Hovering—Sideward Flight Sideward hovering flight may be necessary…

  Chapter 6: Flight Controls › Flight Control Systems › V-Tail

  This motion is called yaw. Like the other primary control surfaces, the rudder is a movable surface hinged to a fixed surface in this case, to the vertical stabilizer or fin. The rudder is controlled by the left and right ... rudder moves left. This alters the airflow around the vertical stabilizer/rudder and creates a sideward lift that moves the tail to the right and yaws the nose of the airplane to the left. Rudder effectiveness increases with speed; therefore, large…

  Chapter 6: Flight Controls › Flight Control Systems › Elevator

  series of mechanical linkages. Aft movement of the control column deflects the trailing edge of the elevator surface up. This is usually referred to as the up-elevator position. [Figure 6-10] Figure 6-8. Coupled ailerons and rudder. Figure ... position decreases the camber of the elevator and creates a downward aerodynamic force, which is greater than the normal tail-down force that exists in straight-and-level flight. The overall effect causes the tail of the aircraft to move…
