Mechanism Analysis of Smart Cue on Aircraft for Loss of Control Mitigation

Abstract

This paper analyzes the mechanism of the smart inceptor on the aircraft, as a means to mitigate human-vehicle system loss-of-control. We divide the smart inceptor cue into three modes: the smart cue on the human pilot, the smart cue on the flight control system and the smart cue on both of them. The control mechanism of these three modes is developed and analyzed in depth. To evaluate the effect of the three modes, we utilize an intelligent human pilot model to establish the human-vehicle system with the smart inceptor and a scalogram-based pilot induced oscillation metric to predict the handling qualities of the three modes. This paper presents details of the cueing modes and the results of the prediction focused on effectiveness of these modes in preventing the pilots from entering a loss-of-control event. The simulation results indicate that the smart cue on both of them was the most effective method to mitigate the impact of the pilot-aircraft system oscillations for the given failure scenarios. It embodies the function of pilot-aircraft cooperation. INDEX TERMS Flight simulation, human-vehicle system, human pilot model, interface, manual control.
