Abstract
An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A dual-redundant propellor servo drive provides propellor control, and a dual-redundant mixture servo drive controls an air-fuel mixture. A first processor and a second processor are communicatively coupled with the dual-redundant propellor servo drive and the dual-redundant mixture servo drive and with each other to provide dual-redundant propellor and mixture control. The throttle control lever provides a single lever for pilot control of aircraft power, and the throttle control configuration is compatible with an auto-land capability.
