  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…

  helicopter. Due to inertia, it requires some small time period for the 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 to hover and safely recover the helicopter should a malfunction occur. 5. Hovering too low, resulting in occasional touchdown. 6. Becoming overly confident over prepared surfaces when taking…

  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…

  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 9: Basic Flight Maneuvers › Taxiing › Air Taxi

  Hover Taxi A hover taxi is used when operating below 25 feet above ground level (AGL). [Figure 9-9] Since hover taxi is just like forward, sideward, or rearward hovering flight, the technique to perform it is not presented here ... Taxi An air taxi is preferred when movements require greater distances within an airport or heliport boundary. [Figure 9-10] In this case, fly to the new location; however, it is expected that the helicopter will remain below 100 feet…

  Chapter 7: Helicopter Performance › Performance Charts › Sample Hover Problem 2

  Sample Hover Problem 1 You are to fly a photographer to a remote location to take pictures of the local wildlife. Using Figure 7-4, can you safely hover in ground effect at your departure point with the following conditions ... First enter the chart at 8,000 feet pressure altitude (point A), then move right until reaching a point midway between the +10 °C and +20 °C lines (point B). From that point, proceed down to find the maximum gross…
