WebSep 1, 2024 · Pilot-induced oscillation (PIO) refers to an inadvertent and sustained oscillation in the aircraft attitude or track caused by inconsistency between the pilot's … The phugoid has a nearly constant angle of attack but varying pitch, caused by a repeated exchange of airspeed and altitude. It can be excited by an elevator singlet (a short, sharp deflection followed by a return to the centered position) resulting in a pitch increase with no change in trim from the cruise condition. As speed decays, the nose drops below the horizon. Speed increases, and the nose climbs above the horizon. Periods can vary from under 30 seconds for light aircraft to …
