Abstract : The present concept of automatic throttle control, as employed in Navy carrier-based aircraft, was investitated. The aircraft chosen for study was the A-7E. The powerplant was the TF41-A-2, a turbofan engine with a relatively slow throttle response in the approach power range. The effects of additional inputs to the approach power compensator were evaluated. It was shown that a considerable increase in performance could be achieved through the incorporation of longitudinal feedback. In addition, the limitations imposed on performance by large engine lags were found to be much less severe for systems with longitudinal feedback. The modifications suggested require a redesign of the approach power compensator system currently in use by the Navy. (Author)
