This maneuver is used to decelerate from forward flight to a hover. It is often used to abort takeoffs, stop if something blocks the helicopter's flight path, or simply to terminate an air taxi maneuver.
 

The maneuver begins with a reduction in collective (left hand) a right pedal input (r. foot) and a pull of the cyclic aft (right hand, pulling towards you).  This movement redirects the downward force generating by the rotor blades and acts to slow the forward progress of the helicopter.  As the speed is reduced, nose the helicopter forward with a left pedal input and a gentle forward cyclic.  This redirects the downward force back into the ground beneath the helicopter and creates ground effect, the soft cushion of air used at low hovering altitudes.
