The Rolls-Royce/S.N.E.C.M.A. Olympus 593 employs a variable area primary nozzle and has a reheat system - both novelties to civil aviation. The main purpose of this paper is to show that these innovations are accommodated without generating crew work load problems. Consequently the paper is aimed primarily at the airline user rather than the control system specialist. A brief description is given of the basic engine electrical control and its interface with the intake system. The flight deck mounted thrust management controls and indicators are identified and their use described during the course of a typical flight. The subject of engine mechanical condition monitoring is also examined.
