Abstract: An engine trim control unit for monitoring the operational characteristics of one or more gas turbine engines on an aircraft from the cockpit thereof and sequentially adjusting selected ones of a plurality of engine parameters for the engines from the cockpit is comprised of a controller (10) incorporating digital microcircuitry and interfacing with engine-side components via a multiplexer (12); tranducers for generating signals representative of the condition of at least one structurally variable engine component indicative of (i) variable stator vane position (14) and (ii) engine compressor airflow bleed (16); and wherein the multiplexer selectively routes trim command signals to remotely actuable trim head members in operative engagement with engine-mounted trim screws for selectively adjusting at least one variable engine parameter including (i) engine vane and bleed control (70), (ii) engine compressor airflow bleed (72), (iii) approach idle (82), (iv) minimum idle (84) and (v) takeoff power (72), and a
