Abstract:

Pilot induced oscillation(PIO) of a piloted aircraft is described from flight control system(FCS) point of view. The effects of a system stick force, transmission ratio, clearance, friction and flight control servoactuator on PIO are analyzed. The possibility and tendency caused by PIO are concisely explained with a vector diagram, which is of value for reference in design of FCS and analysis of PIO.

Key words: pilot induced oscillation, flight control, vectors
