  Chapter 3: Helicopter Flight Controls › Cyclic Pitch Control

  Cyclic Pitch Control The cyclic pitch control (or simply “cyclic”) is usually projected upward from the cockpit floor, between the pilot’s legs or between the two pilot seats in some models. [Figure 3-4] This primary flight control allows ... total lift force is always perpendicular to the tip-path plane of the main rotor. The purpose of the cyclic pitch control is to tilt the tip-path plane in the direction of the desired horizontal direction. The cyclic controls…

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

  Cyclic The cyclic control is usually located between the pilot’s legs and is commonly called the “cyclic stick” or simply “cyclic.” On most helicopters, the cyclic is similar to a joystick; however, Robinson helicopters have unique T-bar cyclic ... control systems. A few helicopters have cyclic controls that descend into the cockpit from overhead while others use side cyclic controls. The control is called the cyclic because it can vary the pitch of the rotor blades throughout each revolution…

  clockwise system). If cruising airspeed is the same as or slightly above descending airspeed, simultaneously apply the necessary cyclic pressure to obtain the approximate descending attitude. If the pilot wants to decelerate, the cyclic must be moved ... pilot desires to descend with increased airspeed, then forward cyclic is all that is required if airspeed remains under the limit. As the helicopter stabilizes at any forward airspeed, the fuselage attitude will streamline due to the airflow over…

  decrease airspeed, apply rearward pressure on the cyclic and lower the collective, as necessary, to maintain altitude. Figure 9-1. Maintain straight-and-level flight by adjusting the rotor tip-path plane forward but adjusting the collective as necessary ... power may need to be taken out or the nose of the helicopter may be too high, requiring a cyclic adjustment. Although the cyclic is sensitive, there is a slight delay in control reaction, and it is necessary to anticipate…

  Chapter 11: Helicopter Emergencies and Hazards › Autorotation › RPM Control

  inertia rotor systems has been studied in simulator flight evaluations which indicate that the simultaneous application of aft cyclic, down collective, and alignment with the relative wind (trim) at a wide range of airspeeds, including cruise airspeeds, is critical ... autorotations in a turn. Upward movement of the collective reduces the rpm and downward movement increases the rpm. Cyclic movement is primarily associated with attitude/airspeed control in powered flight but may not be given the credit appropriate for rotor…

  maneuver. [Figure 9-7] Begin the maneuver from a normal hovering height by applying forward pressure on the cyclic. As movement begins, return the cyclic toward the neutral position to maintain low groundspeed—no faster than a brisk walk. Throughout ... maneuver, maintain a constant groundspeed and path over the ground with the cyclic, a constant heading with the antitorque pedals, altitude with the collective, and the proper rpm with the throttle. To stop the forward movement, apply rearward cyclic pressure…
