Abstract

An integrated aircraft survivability equipment state machine. Aircraft survivability sensors provide aircraft survivability states that are routed to a finite state machine. Data processing, data generation, data representation, queueing tactical information and initiation of aircraft survivability counter measures are controlled by the state oriented approach. Systems state can be altered based on mission defined variables. Counter measures can be initiated based on correlated threat data and other functions such as failure recording and threat database generation functions. All individual aircraft survivability subsystems are integrated and controlled by the state machine. The state machine manages the ASE subsystem power as far as built-in testing and controls for the integrated ASE system. Overall threat data presentation is controlled and driven by the system state.
