  Chapter 11: Helicopter Emergencies and Hazards › Common Errors › Autorotation with Turns

  Autorotation with Turns Turns (or a series of turns) can be made during autorotation to facilitate landing into the wind or avoiding obstacles. Turns during autorotation should be made early so that the remainder of the autorotation is flown identically ... straight-in autorotation. The most common turns in an autorotation are 90 degrees and 180 degrees. The following technique describes an autorotation with a 180-degree turn. The pilot establishes the aircraft on a downwind heading at the recommended airspeed…

  Risk Management during Autorotation Training The following sections describe enhanced guidelines for autorotations during rotorcraft/helicopter flight training, as stated in Advisory Circular (AC) 61-140. There are risks inherent in performing autorotations in the training environment, and in particular ... degree autorotation. This section describes an acceptable means, but not the only means, of training applicants for a rotorcraft/helicopter airman certificate to meet the qualifications for various rotorcraft/helicopter ratings. You may use alternate methods for training if you establish that…

  Chapter 9: Basic Flight Maneuvers › Hovering › Technique

  Hovering A stationary hover is a maneuver in which the helicopter is maintained in nearly motionless flight over a reference point at a constant altitude and on a constant heading. Technique To maintain a hover over a point, use sideview ... altitude. When these changes are noted, make the necessary control inputs before the helicopter starts to move from the point. To detect small variations in altitude or position, the main area of visual attention needs to be some distance from…

  Moving vertically to the bottom of the graph (point C), with the existing density altitude, the maximum gross weight under which the height/velocity diagram is applicable is 2,500 pounds. The production of performance charts and diagrams for helicopters ... regulatory, the pilot should carry out a full risk assessment to carefully consider the higher risk before operating within the shaded areas of the height/ velocity diagram. Autorotational Performance Most autorotational performance charts state that autorotational descent performance…

  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 11: Helicopter Emergencies and Hazards › Autorotation › Technique (How to Practice)

  Practicing Power Failure in a Hover Power failure in a hover, also called hovering autorotation, is practiced so that a pilot can automatically make the correct response when confronted with engine stoppage or certain other emergencies while hovering. The techniques ... section are for helicopters with a counterclockwise rotor disk and an antitorque rotor. Technique (How to Practice) To practice hovering autorotation, establish a normal hovering height (approximately 2–3 feet) for the particular helicopter being used, considering load and atmospheric…
