Pagination or Media Count:
The report describes an automatic throttle control system that limits maximum throttle lever position as a function of engine pressure ratio. Limit EPR is sensed by an outside air temperature gauge calibrated in EPR as based on thrust level limits contained in the aircraft operators manual. Limit control of EPR is accomplished by stopping the throttle lever when the observed EPR equals the temperature sensed limit value. The EPR limit control was designed primarily to permit use of maximum permissible thrust during takeoff and go- around maneuvers with an automatic throttle system utilizing a single servo.
