PREPARATION INSTRUCTION
Aim
For the student to learn how to:
depart from the hover to the climb approach the hover from forward flight.
Review
Straight and level flight, climbs and descents, hovering.
Motivation
Accurate transitions are extremely important, particularly
in an operational environment.

Teaching Points
? Transition to the climb
Describe the transition from the hover to the climb as
follows:
Establish a steady hover into wind.
Make a clearing turn and check that the area is clear. Complete the pre-take-off check.
Select an outside reference to help in directional control, and ease the cyclic forward slightly to initiate movement.
At the same time, if required, adjust power sufficiently to maintain height.
Apply enough forward cyclic to overcome flap-back. Select the climb attitude and power.
Prevent yaw throughout and adjust the attitude as required to maintain the climb attitude.
? Transition from forward flight to the hover (standard approach)
Explain that the transition to the hover involves two separate requirements that have to be combined into one coordinated manoeuvre:
Height reduction: Height must be reduced from the approach altitude to the hover height above ground. Explain the straight-line or constant angle approach, describing the visual indications.
Speed reduction: Speed must be progressively reduced from the approach airspeed to a zero groundspeed at the hover. Varying approach angles and/or wind conditions will cause the airspeed to vary a great deal from one approach to another. It is vital, therefore, that the student learns to refer to groundspeed only.
Describe the procedure as follows:
Approach the landing spot into the wind at a specific altitude and airspeed.
