F-16 failure detection isolation and estimation study

The authors discuss the evaluation of a modified multiple hypothesis FDIE (failure detection, isolation, and estimation) scheme in a high-fidelity nonlinear six-degree-of-freedom F-16 simulation. They present examples of detection of horizontal tail failure at an air combat maneuver entry flight condition and rudder failure while maneuvering at supersonic speed and low altitude. The simulation results indicate that the FDIE can function properly within a fraction of a second. Thus, further control law reconfiguration and positive pilot alert are possible to benefit the F-16´s combat capabilities
