  Chapter 9: Basic Flight Maneuvers › Approaches › Technique

  Technique On final approach, at the recommended approach airspeed and at approximately 300 feet AGL, the helicopter should be on the correct ground track (or ground alignment) for the intended landing site, but the axis of the helicopter does ... have to be aligned until about 50-100 feet AGL to facilitate a controlled approach. [Figure 9-20] Just prior to reaching the desired approach angle, begin the approach by lowering the collective sufficiently to get the helicopter decelerating…

  item that alters the landing speed or deceleration rate during the landing roll affects the landing distance. The effect of gross weight on landing distance is one of the principal items determining the landing distance. One effect of an increased ... gross weight is that a greater speed is required to support the aircraft at the landing AOA and lift coefficient. For an example of the effect of a change in gross weight, a 21 percent increase in landing weight requires…

  Chapter 10: Advanced Flight Maneuvers › Shallow Approach and Running/Roll-On Landing

  Shallow Approach and Running/Roll-On Landing Use a shallow approach and running landing when a high-density altitude, a high gross weight condition, or some combination thereof, is such that a normal or steep approach cannot be made because of insufficient ... power to hover. [Figure 10-5] To compensate for this lack of power, a shallow approach and running landing makes use of translational lift until surface contact is made. If flying a wheeled helicopter, a roll-on landing…

  Chapter 10: Advanced Flight Maneuvers › Steep Approach › Technique

  Technique On final approach, maintain track with the intended touchdown point and into the wind as much as possible at the recommended approach airspeed [Figure 10-4, position 1]. When intercepting an approach angle of 13° to 15°, begin ... approach by lowering the collective sufficiently to start the helicopter descending down the approach path and decelerating (position 2). Use the proper antitorque pedal for trim. Since this angle is steeper than a normal approach angle, reduce the collective more…

  Chapter 1: Introduction to the Helicopter › Controlling Flight › Throttle

  Throttle Helicopter rotors are designed to operate at a specific rpm. Figure 1-11. The throttle control mounted at the end of the collective control. The throttle controls the power produced by the engine, which is connected to the rotor ... transmission. The purpose of the throttle is to maintain enough engine power to keep the rotor rpm within allowable limits to produce enough lift for flight. In single-engine helicopters, if so equipped, the throttle control is typically a twist…

  Chapter 9: Basic Flight Maneuvers › Common Errors › Crosswind During Approaches

  Technique As the helicopter nears the surface, increase the collective, as necessary, to cushion the landing on the surface, terminate in a skids-level attitude with no forward movement. Common Errors 1. Terminating to a hover, and then making ... vertical landing. 2. Touching down with forward movement. 3. Approaching too slow, requiring the use of excessive power during the termination. 4. Approaching too fast, causing a hard landing 5. Not maintaining skids aligned with direction of travel at touchdown…
