- 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…
- Chapter 9: Basic Flight Maneuvers › Hovering—Sideward Flight › Technique
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 ... maintain proper rpm. 5. Failure to maintain alignment with direction of travel. Hovering—Sideward Flight Sideward hovering flight may be necessary to move the helicopter to a specific area when conditions make it impossible to use forward flight. During…
- Chapter 9: Basic Flight Maneuvers › Hovering—Rearward Flight › Technique
Common Errors 1. Exaggerated movement of the cyclic, resulting in overcontrolling and erratic movement over the surface. 2. Failure to use proper antitorque pedal control, resulting in excessive heading change. 3. Failure to maintain desired hovering height. 4. Failure ... maintain proper rpm. 5. Failure to make sure the area is clear prior to starting the maneuver. Hovering—Rearward Flight Rearward hovering flight may be necessary to move the helicopter to a specific area when the situation is such that…
- Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Antitorque System Failure
following the manufacturer’s recommendations regarding operating limits and procedures and periodic maintenance and inspections, many system and equipment failures can be eliminated. Certain malfunctions or failures can be traced to some error on the part of the pilot; therefore ... appropriate flying techniques and use of threat and error management may help to prevent an emergency Antitorque System Failure Antitorque failure usually falls into one of two categories. One is failure of the power drive portion of the tail rotor…
- 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 › Hovering › Common Errors
Common Errors 1. Tenseness and slow reactions to movements of the helicopter. 2. Failure to allow for lag in cyclic and collective pitch, which leads to overcontrolling. It is very common for a student to get ahead of the helicopter ... helicopter to respond. Confusing attitude changes for altitude changes, which results in improper use of the controls. 4. Hovering too high, creating a hazardous flight condition. The height velocity chart should be referenced to determine the maximum skid height…
