Active gust alleviation

Definition

Active gust alleviation is a control strategy used in aviation to reduce the impact of sudden and unexpected changes in airflow, or gusts, on an aircraft's stability and performance. This technique employs real-time adjustments to control surfaces, allowing the aircraft to maintain a steady flight path despite turbulence. By actively countering disturbances, active gust alleviation enhances passenger comfort and protects the structural integrity of the aircraft.
