What Does PIO Stand For?

PIO stands for Pilot Induced Oscillation

Pilot Induced Oscillation (PIO) refers to an aerodynamic phenomenon in which an aircraft experiences oscillatory motion due to the actions of the pilot. This condition can arise from the pilot's control inputs in response to perceived instability, leading to a feedback loop of oscillations that can compromise aircraft control and safety. PIO is critical to understand in flight training and aircraft design to ensure effective handling characteristics and to mitigate risks associated with pilot-induced movements.
