PIO: Pilot Induced Oscillation
About PIO(Pilot Induced Oscillation) A vibration phenomenon that is unintentionally excited by the correlation between the aircraft’s control system and the pilot. This phenomenon has been observed in the Wright Flyer, the first aircraft, and in the latest fighter aircraft (X-36), and in the worst case, it can lead to a crash. Although the name gives the impression that the cause is the pilot, the cause is the aircraft (Flight Control System). PIO is classified into the following four types…
