Fixed and rotary wing pilots alike are familiar with potential instabilities or with annoying limit
cycle oscillations that arise from the effort of controlling aircraft with high response actuation …

Understanding, predicting and supressing the inadvertent aircraft oscillations caused by
Aircraft/Rotorcraft Pilot Couplings (A/RPC) is a challenging problem for designers. These are …

Unintended and unexpected oscillations or divergences of the pilot-rotorcraft system have
become a critical issue for augmented helicopters with modern flight control systems. The …

Tiltrotor aircraft are challenging machines to design considering the various operating
conditions and multipurpose missions that are expected to be performed by this complex …

The involuntary interaction of pilots with vehicles is often an undesired consequence of the
biodynamic feedthrough of cockpit vibrations into the control system in relation with the …

This paper presents the current status of the investigation conducted by the authors as part
of the GARTEUR HC AG-16 on Rotorcraft-Pilot Couplings (RPCs) governed by …

This paper presents the development of a multiloop pilot model for use in boundary-
triggered pilot-induced oscillation investigations. In doing so, the point-tracking and …

This paper discusses the aeroelastic interaction between the helicopter and the pilot called
collective bounce. The problem is mostly studied in the time domain, using the multibody …

THE traditional view of how pilots fly a wide range of tasks involves an initial acquisition,
followed by point tracking (PT) of aircraftflight path or attitude. Pilot-induced oscillations …

Significant effort has been expended to develop criteria to predict the susceptibility of an air
vehicle to so-called pilot-induced oscillations. Much of this work has been carried out for …
