  Chapter 3: Helicopter Flight Controls › Collective Pitch Control

  Collective Pitch Control The collective pitch control (or simply “collective” or “thrust lever”) is located on the left side of the pilot’s seat and is operated with the left hand. The collective is used to make changes ... pitch angle of the main rotor blades and does this simultaneously, or collectively, as the name implies. As the collective pitch control is raised, there is a simultaneous and equal increase in pitch angle of all main rotor blades…

  Chapter 3: Helicopter Flight Controls › Governor/Correlator

  Figure 3-2. A twist grip throttle is usually mounted on the end of the collective lever. The throttles on some turbine helicopters are mounted on the overhead panel or on the floor in the cockpit. Some helicopters ... have correlators or governors and require coordination of all collective and throttle movements. When the collective is raised, the throttle must be increased; when the collective is lowered, the throttle must be decreased. As with any aircraft control, large adjustments…

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

  Collective The collective pitch control, or collective, is located on the left side of the pilot’s seat with a pilot-selected variable friction control to prevent inadvertent movement. The collective changes the pitch angle of all the main rotor ... blades collectively (i.e., all at the same time) and independently of their positions. Therefore, if a collective input is made, all the blades change equally, increasing or decreasing total lift or thrust, with the result of the helicopter increasing…

  Chapter 9: Basic Flight Maneuvers › Straight-and-Level Flight › Technique

  order to counteract this, the pilot must find the correct power setting to maintain level flight by adjusting the collective. [Figure 9-1] The horizontal stabilizer aids in trimming the helicopter about its transverse, horizontal axis, and reduces the amount ... which produces a lifting force in a downward direction. When in straight-and-level flight, any increase in the collective, while holding airspeed constant, causes the helicopter to climb. A decrease in the collective, while holding airspeed constant, causes…

  However, use cyclic control, as required, to ensure a vertical descent and a level attitude. Do not adjust the collective on entry. Helicopters with low inertia rotor disks settle immediately. Keep a level attitude and ensure a vertical descent with ... response decreases, so compensation for the winds will require more cyclic input. At approximately 1 foot AGL, apply upward collective control, as necessary, to slow the descent and cushion the landing without arresting the rate of descent above the surface…

  Chapter 11: Helicopter Emergencies and Hazards › Dynamic Rollover › Slope Takeoffs and Landings

  Slope Takeoffs and Landings During slope operations, excessive application of cyclic control into the slope, together with excessive collective pitch control, can result in the downslope skid or landing wheel rising sufficiently to exceed lateral cyclic control limits ... upslope skid or wheel, then slowly lower the downslope skid or wheel using combined movements of cyclic and collective. If the helicopter rolls approximately 5–8° to the upslope side, decrease collective to correct the bank angle and return…
