After a structural damage or component failure during any flight mode, aircraft dynamics are dramatically altered. A quick and adequate stabilization effort is crucial. Flight dynamics for several failure scenarios are analyzed. Necessary amounts of control deflections for postfailure trim are calculated. These trim values are used as control input in an open loop manner and validity of this approach is tested via flight simulations. Alternatively, a closed loop flight control system, which does not need the postfailure trim values, is also designed. This closed loop controller is based on a linearized aircraft model whereas flight simulations are based on nonlinear aircraft dynamics.
