Pilot Induced Oscillations (PIO) are described as pilot-aircraft dynamic couplings which can lead to instability in an otherwise stable system. Previous and ongoing research has attempted to explain, predict, and avoid such oscillations. In contrast to other research, this effort backs away from pilot models and PIO avoidance and focuses on the characteristics of the pilot before, during, and a...

Pilot-Induced Oscillation (PIO) is an unwanted, inadvertent phenomenon that has the ability to damage the aircraft completely. This paper suggests a novel control method that can damp PIO after predicting its occurrence. The specific point of this control algorithm is that it contains a preprocessor that will not let the controller be activated unless in the case of probable PIOs, so pilot comm...

A simple feedback-control theory analysis of lateral control of a towed glider shows the importance of perceiving the lateral tug velocity from the rotation rate of the towrope. A bank component relative to the tug's bank angle that is proportional to the rotation rate should be applied by the pilot to damp lateral motion. Pilot-induced oscillations result from prime attention to the relative p...
