As the airplane is aligned with the takeoff path, takeoff
power is applied smoothly and as rapidly as the power-
plant will accept it without faltering. As the airplane
accelerates, enough back-elevator pressure should be
applied to establish a positive angle of attack and to
reduce the weight supported by the nosewheel.
When the airplane is held at a nose-high attitude
throughout the takeoff run, the wings will, as speed
increases and lift develops, progressively relieve the
wheels of more and more of the airplane's weight,
thereby minimizing the drag caused by surface irregularities or adhesion. If this attitude is accurately maintained,
the airplane will virtually fly itself off the ground,
becoming airborne at airspeed slower than a safe climb
speed because of ground effect.
