Use of Power High Round Out throttle so the additional thrust and lift are removed and the  airplane remains on the ground. and control usage, the airplane may stall or sink rapidly,  contacting the ground with a hard impact. Whenever a slow speed approach is noted, apply power to  accelerate the airplane and increase the lift to reduce the sink  rate and to prevent a stall. This is done while still at a high  enough altitude to reestablish the correct approach airspeed  and attitude. If too slow and too low, it is best to execute a  go-around. Sometimes when the airplane appears to temporarily stop  moving downward, the round out has been made too rapidly  and the airplane is flying level, too high above the runway.  Continuing the round out further reduces the airspeed and  increases the AOA to the critical angle. This results in the  airplane stalling and dropping hard onto the runway. To  prevent this, the pitch attitude is held constant until the  airplane decelerates enough to again start descending. Then  the round out is continued to establish the proper landing  attitude. This procedure is only used when there is adequate  airspeed. It may be necessary to add a slight amount of power  to keep the airspeed from decreasing excessively and to avoid  losing lift too rapidly. Power can be used effectively during the approach and round  out to compensate for errors in judgment. Power is added  to accelerate the airplane to increase lift without increasing  the AOA and the descent slowed to an acceptable rate. If  the proper landing attitude is attained and the airplane is  only slightly high, the landing attitude is held constant and  sufficient power applied to help ease the airplane onto the  ground.
