Approach

An approach is the part of a flight where the helicopter descends from circuit height and flares to a hover above the runway or landing area.

Steep approaches are the first steps towards practicing autorotations, and are required as part of the British Model Flying Association B-certificate test.

During the approach, the collective is lowered to reduce lift. As the landing area is approached, the helicopter's nose is raised to slow the helicopter, and the collective is lowered further still to compensate for the energy transferred from speed to height. Finally, as the helicopter slows to a hover, it loses translational lift and the collective must be raised significantly to maintain altitude.
