? use the cyclic to maintain position. Stress the need to avoid sideways or rearwards drift.
? use the collective to control the rate of descent
? use the pedals to prevent yaw.
Point out the need to anticipate the increase in ground effect during a landing in light or nil wind conditions.
Point out the need to anticipate ground resonance, if applicable to type.
AIR EXERCISE
Demonstrate the take-off to the hover. Demonstrate hover check.
Student practice
Demonstrate landing from the hover. Student practice
TIPS FOR INSTRUCTORS
Do not teach this exercise unless the student can consistently maintain a steady hover.
Ensure students keep looking at their reference points in front of the helicopter and not down at the ground.
Monitor the collective closely on the initial attempts to land so as to guard against sudden and excessive movements. Ensure once landing is achieved, the collective is smoothly lowered full-down.
It is generally an advantage to strive for smoothness and accuracy before speed during these manoeuvres.

Student technique should nonetheless be developed to the point where contact with the ground is made and broken cleanly, particularly in helicopters prone to ground resonance.
When the student is working smoothly and accurately, introduce lifting from the ‘skids light’ condition to a low hover before going to normal hover height to preclude dynamic rollover.
Be aware that, when getting close to the surface, some students try to ‘feel’the ground by rocking the cyclic laterally.
As with hovering, this exercise is very tiring; break it up by practising other exercises when necessary.
