Human Pilot Interaction with Fast Adapting Flight Control System

Interaction between the adaptive behavior of a human pilot and an adaptive flight control system (FCS) usually leads to undesirable adverse effects such as pilot-induced oscillations (PIO). This paper presents an analysis of this interaction in the case of a fast adapting FCS. The analysis shows that, although a pilot will have some nonlinear behavior at the moment when a failure occurs, the fast adapting FCS allows to keep the physical workload low and the pilot behavior remains the same as before the failure. This effectively mitigates the adverse effects seen in the literature.Copyright (c) 2022 The Authors.
