Exercise 4: Effects of Controls



Review lesson 1, 2 and 3. To further develop the students understanding of the individual effects of the flight controls in forward flight



  1. Demonstrate the primary effects of the Cyclic, Collective and Anti-torque/Yaw pedals on:
    • Attitude, height and speed
    • Power and torque
    • Direction
  2. Allow the student to perform the demonstrated primary effects
  3. Demonstrate the secondary effects of the Cyclic, Collective and Anti-Torque/Yaw pedals on:
    • Effect of speed – Flap back
    • Effect of power changes – Torque and nose pitching tendencies
    • Effect of yaw – Spiral
    • Effect of disc loading – RRPM and MAP
  4. Allow the student to perform the demonstrated secondary effects
  5. Effect of controls when selecting governor, hydraulics on/off if applicable
  6. Effect of control friction
  7. Demonstrate stability/instability of the helicopter
  8. Demonstrate the use of carburetor heat, throttle and trim devices and allow the student to practice the correct application of the devices.



 At the completion of this exercise the student will be able to sign out the relevant authorization sheets, confirm that the helicopter is within maintenance inspection interval, express certain considerations and risk mitigation solutions in the immediate helicopter environment, use checklists to conduct a preflight inspection and start the engine. They will have a better understanding of inflight procedures and the flying environment as well as the training airspace. They will have an understanding of the primary and secondary effect of the flying controls as well as the effect of the ancillary controls. They will understand the motor force required to manipulate the controls and be conscious of the correct flight posture and how to hold the controls for best result. They will become increasingly aware of the radio procedures involved in flying through the local airspaces, as well as the applicable frequencies and how and when to select them. After flight, along with instructor assistance they will be able to shut down the helicopter, conduct a post flight inspection, sign the authorization sheet and flight folio. Complete a logbook entry and sign their student training file entry.
