www.faa.govwith power to offset the drag produced by the flaps, the landing flare becomes critical. The drag produces a high sink rate that must be controlled with power, yet failure to reduce power at a rate so that the power is idle at touchdown allows the airplane to float down the runway. A reduction in power too early can

AIRCRAFT STABILITY AND CONTROL ANALYSIS - PUC-Rio
www.maxwell.vrac.puc-rio.brThe reduction of the disturbance with the time indicates that energy is being dissipated. This condition is called positive dumping, in this condition, the forces and moments will oppose the motion of the aircraft and dump the disturbance. An unstable aircraft has negative aerodynamic damping. It is possible to fly such aircraft, but a
