All rights reserved.PIO (Pilot-Induced Oscillations) phenomena have been widely explored over the past recent years and led to the development of mathematical models to describe human pilot behavior as well as frequency domain analysis criteria. However, both these pilot models and prediction criteria have been developed neglecting the influence of airframe flexibility. Since aircraft are becoming more flexible, this influence has to be considered during the development of fly-by-wire systems. In this paper, we address the effects of aeroelastic dynamics in aircraft handling qualities analysis using an adequate representation of the aircraft flight dynamics as a flexible body and mathematical pilot models.
