Disturbance

An engineering term for any changing external force initiating a dynamic change in equilibrium. In flight, a wind gust will cause a disturbance to the trimmed or steady flight condition. A pilot may introduce a disturbance in the form of a control input to maneuver or change the flight condition of the aircraft. A disturbance, such as a wind gust or pilot reaction may initiate other dynamic responses of the aircraft or pilot. In engineering terms, a disturbance can initiate a “transient” response in an aircraft or object or component of an aircraft.
