The pilot of an aircraft initiates rotation after reaching V(r) speed in order to obtain the scheduled
takeoff performance. The term rotation is used because the aircraft
pivots around the axis of its main
landing gear due to manipulation of the flight controls to make this change in aircraft attitude. The nose is usually brought to a 5 - 20 degree nose up attitude to create sufficient lift from the wings.
At 130 KCAS, the pilot moved the control column
aft to
8.4 degrees to initiate rotation as the aircraft passed the 5500 ft mark of
the runway 24. The aircraft began to rotate.
