Student practice Demonstrate climbing turns, rolling out onto a nominated heading and levelling off at a nominated altitude. Student practice Demonstrate descending turns rolling out onto a selected heading and levelling out at a nominated altitude. Student practice TIPS FOR INSTRUCTORS Emphasise the need for lookout, and the difficulty of spotting other aircraft, particularly when they are below the horizon. It is important that turns be practiced in both directions to show the different visual references in the helicopter. Becuase of the increased emphaisis on accurance, the student should be taught how to monitor instrumentation without sacrificing lookout. Steep turns are covered separately in Exercise 18. Turns in autorotation are covered separately in Exercise 16. 06 HOVERING GROUND SCHOOL POINTS Regaining the hover from movement in any direction requires two attitude changes: one to stop the movement, and a second to stabilise the helicopter. All cyclic movements should be small. Cyclic trim should be employed, if applicable. ? Collective Point out the following: The collective controls the height above ground. Changes in collective pitch will produce yaw and RPM changes unless prevented. ? Throttle Where appropriate to type, describe the use of the throttle to maintain RPM. ? Pedals Ground Effect Flight manual performance charts: ? Hover in-ground effect ? Hover out-of-ground effect HV Graph - Risks Associated PREPARATORY INSTRUCTION Aim For the student to learn how to hover. Motivation This is an exercise fundamental to all helicopter operations.
