    Abstract

    This report presents a scheme to provide analytical redundancy for angle of attack sensor which is an important feedback for flight control system of a high performance aircraft / missile and also for aircraft stall warning system. The filtering and fusion scheme for reconstruction of angle of attack utilizes the rigid body kinematic equations of the aircraft and the data from INS and air data computer in an extended Kalman filter. The scheme is implemented in MATLAB / SIMULINK environment and validated with both flight simulator data as well as flight data. The13; scheme provides an additional source of angle of attack which is reliable and reasonably accurate.
