On-the-fly procedure development for flight re-planning following system failures

Faced with a failure aboard a modern aircraft, pilots must generate a flight-plan to effectively and safely control the plane to touchdown. However, forming this flight-plan involves predicting the complex interaction of the hybrid discrete-continuous behaviors of the pilot-aircraft system. This prediction must be accurate; otherwise the aircraft may lack the ability to correct for any deviations, placing it in a hazardous flight regime. It is hypothesized that an in-flight replanning tool may aid the pilot in forming and verifying flight-plans. Following the conceptual development of the needs of such a display, a prototype was constructed to test the concept. Issues, with fasttime simulation, pilot-aircraft modeling, and pilot interfaces were explored in this development.
