Dutch roll being one of the most difficult disturbing motions of the fixed wing aircraft, could be damped with the help of an autopilot control system. The purpose of this research work is to design such autopilot control system that could damp the oscillations created by this Dutch Roll and thereby bringing the aircraft to equilibrium flight condition. Though conventional engineers use yaw dampers to damp such motions, development of electronics and autopilot board’s invention has led Avionics Engineers to design such creation for the benefit of society. Also, the use of Autopilot Control system is reducing the pilot’s work especially in UAV industries as well. Most of the mission for small payload capacity carrying mission uses fixed wing UAV and embedding such autopilot boards become conventional in UAV sectors. Though the work done in this manuscript is not for UAV purposes, in future this work would help in adopting the UAV technology for passenger aircrafts as well.
