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

    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 grip mounted on the collective control, but it can also be a lever ... 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 direction that is to control forward and back, right and left. The collective…

  • Chapter 4: Helicopter Components, Sections, and Systems › Stability Augmentations Systems › Autopilot

    helicopter in pitch and roll; one servo controls fore and aft cyclic, and another controls left and right cyclic. A three-axis autopilot has an additional servo connected to the antitorque pedals and controls the helicopter in yaw. A four ... central computer. This computer receives data input from the flight instruments for attitude reference and from the navigation equipment for navigation and tracking reference. An autopilot has a control panel in the cockpit that allows the pilot to select…

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

    power to rejoin the needles by approximately 100 feet AGL. If a go-around is to be made, the cyclic control should be moved forward to resume forward flight. In transition from a practice autorotation to a go-around, exercise ... concentration needed when transitioning from powered flight to autorotation and then back again to powered flight. For helicopters equipped with the power control on the collective, engine power must be brought from flight power to idle power and then back…

  • Chapter 9: Basic Flight Maneuvers

    helicopters perform the same way. Even when flying the same model of helicopter, wind, temperature, humidity, weight, and equipment make it difficult to predict just how the helicopter will perform. Therefore, this chapter presents the basic flight maneuvers ... governor is doing the work for you. In addition, instead of using the terms “collective pitch control” and “cyclic pitch control” throughout the chapter, these controls are referred to as just “collective” and “cyclic…

  • Chapter 9: Basic Flight Maneuvers › Taxiing › Technique

    however, do not taxi faster than a brisk walk. If the helicopter is equipped with brakes, use them to help slow down. Do not use the cyclic to control groundspeed. Begin the maneuver from a normal hovering height by applying…

  • Chapter 6: Weight and Balance › Balance › Lateral Balance

    normal flight instruction and passenger flights. This is because helicopter cabins are relatively narrow and most optional equipment is located near the centerline. However, some helicopter manuals specify the seat from which a pilot must conduct solo flight. In addition ... position should be checked against the CG envelope. If carrying external loads in a position that requires large lateral cyclic control displacement to maintain level flight, fore and aft cyclic effectiveness could be limited dramatically. Manufacturers generally account for known…
