- Chapter 2: Aerodynamics of Flight › Hovering Flight
Hovering Flight Hovering is the most challenging part of flying a helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The end result is constant ... helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift in the horizontal plane, controlling forward, backward, right and left movement…
- Chapter 9: Basic Flight Maneuvers › Vertical Takeoff to a Hover › Technique
Hover height, rate of ascent, and the rate of descent are controlled by using the collective. Helicopter position and the direction of travel are controlled by the cyclic. After receiving the proper clearance and ensuring that the area is clear ... torque increases, antitorque must be adjusted as well. Therefore, as the aircraft begins to get light on the landing gear, apply appropriate antitorque pedal to maintain aircraft heading. Continue to apply pedals as necessary to maintain heading and coordinate…

lowest possible speed (position 4)—move the cyclic forward to place the helicopter in the proper attitude for landing. This action gives the student an idea of airframe attitude to avoid, because a pilot should never allow ground contact unless ... helicopter is more nose-low than that attitude. Limiting the flare to that attitude may result in slightly faster touchdown speeds but will eliminate the possibility of tail rotor impact on level surfaces. The landing gear height at this time…

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 7: Helicopter Performance › The Effect of Weight Versus Density Altitude › Hovering Performance
Hovering Performance Helicopter performance revolves around whether or not the helicopter can be hovered. More power is required during the hover than in any other flight regime. Obstructions aside, if a hover can be maintained, a takeoff can be made ... especially with the additional benefit of translational lift. Hover charts are provided for in ground effect (IGE) hover and out of ground effect (OGE) hover under various conditions of gross weight, altitude, temperature, and power. The IGE hover ceiling…

surface. 2. 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 make sure the area is clear prior to starting ... maneuver. Hovering—Rearward Flight Rearward hovering flight may be necessary to move the helicopter to a specific area when the situation is such that forward or sideward hovering flight cannot be used. During the maneuver, maintain a constant groundspeed, altitude…
