This article proposes the conventional implementation of a “Altitude-Hold Controller” for a high speed hypothetical aircraft. The static stability, which is called as Stability Augmentation System (SAS), is studied for the system. The stability conditions are analyzed and suitable controller design is developed over the longitudinal motion. The controller is designed by linearizing the longitudinal equation of motions and it is studied for performance issue. The controller design is optimized in order to get a good approximation for the overall flight system. The Root-Locus method is used to get the controller coefficients. The controller is divided into two sections which are; the inner loop that deals with the pitching motion parameters and the outer loop that deals with the altitude reference, flight-path angle on the vertical motion of the aircraft. The simulations, analysis and results are developed in MATLAB/Simulink program. The final results are discovered and expressed over the MATLAB/Simulink.
