Abstract
A method and device for detecting pilot induced oscillations in an aircraft may detect signals having frequencies of between 0.3 Hz and 0.6 Hz within commands signals generated by a pilot for controlling an aerodynamic surface of the aircraft. The energy of the detected signals is analyzed to determine whether significant pilot induced oscillations are present within the command signals, and an indication of the degree of the oscillations is generated for use by the pilot.
