Improved Upset Recovery Strategies Through Explicit Consideration of Pilot Dynamic Behavior

The human pilot is a crucial component of the Pilot/Vehicle System (PVS) and many researchers have recognized that the dynamic behavior of the human should be explicitly considered when analyzing human-in-the-loop systems. This paper focuses on human behavior modeling during upset recovery and how that pilot model is included in the pilotvehicle-system to determine and evaluate recovery techniques. The research discussed herein examines and models experimentally observed (in a simulator) pilot behavior, examines the role of the pilot model in the PVS, and uses the composite PVS model to determine recovery sequences that accommodate the dynamic behavior of the pilot/vehicle couple. Subsequently, the pilot models are updated to estimate how a pilot might behave under distress and new recovery sequences are extracted to accommodate the behavior of the distressed pilot. Simulation results show that explicit consideration of pilot dynamics, particularly the dynamics of the distressed pilot, in the generation of recovery sequences leads to more desirable responses of the PVS.
