For this reason, the collective is seldom moved without coordinating movements of the cyclic, pedals and throttle. This aspect will be covered in the following exercise. ? Throttle Move the twist grip to open and close the throttle. Explain the function of the throttle as appropriate to type explaining that there are secondary effects comprising YAW and RPM changes. ? Tail rotor pedals Movement of the pedals causes a change in pitch of the tail rotor blades. The result of this is a yaw. Stress that, in the cruise, this yaw is a large skidding motion. Explain that there are secondary effects comprising RPM changes and IAS errors.The pedals should not be used to change the helicopter’s direction of flight. ? Ancillary controls Describe the use of the ancillary controls (e.g. carburettor heat, mixture, trim, rotor brake, anti-ice, windscreen, de-fogging, heater, etc.) as appropriate to type. AIR EXERCISE Before take-off: ? make sure the student is seated comfortably and ensure all checks are completed by using a checklist ? demonstrate the correct use of frictions, trims and control adjustments, as appropriate to type ? demonstrate the effect of cyclic control movements on the rotor disc, including how the horizon is used as a reference to interpret the helicopter’s attitude. ? demonstrate opening and closing the throttle. ? Cyclic Control Establish a straight and level cruise at a safe altitude. Demonstrate pitching movement in the normal range. Point out the sensitivity or lag, as appropriate to type. Student practice When the student demonstrates reasonable competency, point out the flight instrument indications. Re-establish a straight and level cruise. Demonstrate rolling movement (gentle and medium turns). Student practice |
