The linear quadratic regulator based autopilot is premeditated for level flight of unmanned aerial vehicle (UAV) which has been achieved lucratively. Diverse modes are utilized for controlling the rates of UAV. The pitch rate is controlled by utilizing the phugoid mode, the roll rate is controlled by utilizing the roll mode and the spiral mode is utilized for yaw rate. The linear quadratic regulator proposes sturdiness at the rate of accomplishment to subjugation over the turbulences and instabilities in order to conquer the favored performance. The FlightGear simulator is utilized for the authentication of the performance of the autopilot. The level flight has been conquered successfully and has been legitimated by utilizing the FlightGear simulator. The simulated results as well as the FlightGear simulator results or the legitimated results are presented in this paper. Microsoft Visual Studio has been employed as a conduit between the MATLAB and FlightGear Simulator.
