An automatic -throttle compensation system has the capability of removing the problem of aircraft speed instability in the carrier landing approach. Various systems have been proposed and tested, each differing in input sensed variables. Two representative systems are investigated analytically and by the use of digital programmed Nyquist plots and analog simulations. An attempt is made to determine optimum gain constants by using various forcing functions in the analog simulation. Comparisons of the responses of the two systems are made using time history analog records. A digital computer stability program e applicable to any aircraft, is included. The writer wishes to express his appreciation for the assistance and encouragement given him by Professor E.J. Andrews of the U.S. Naval Postgraduate School. Gratitude is also due Ling-Temco-Vought Incorporated,, Specialties Incorporated and Bell Aerosystems for providing the necessary data used in the investigation. In particular, the author wishes to thank the Stability and Control Section, Airframe Design Division, of the Bureau of Naval Weapons for the valuable assistance supplied in the form of pertinent technical reports
