NASA’s F-15A Highly Integrated Digital Electronic Control (HIDEC) aircraft nears the runway after a flight out of NASA’s Dryden Flight Research Center, Edwards, Calif. The last project it was used for at Dryden was development of a computer-assisted engine control system that let a plane land safely with only engine power if its normal control surfaces such as elevators, rudders, or ailerons were disabled. The flight control system helped the pilot control the engines to turn the aircraft, climb, descend, and eventually land safely by varying the speed of the engines one at a time or together. The F-15A HIDEC, built as the number eight prototype (Serial #71-0287), was retired.February 8, 1993NASA Photo › F-15 HIDEC Project Description
