FLIGHT 29 MAY 1950 Sundstrand is used on the only civil-approved constant frequency A.C system The Boeing 707 was the first civil aircraft to fly on the world's airlines with a full Constant Frequency A.C. power installation. And the heart of that aircraft's installation is the Sundstrand Drive Unit—the unit proved by many thousands of hours flying experience. English Electric are in production with the Sundstrand Drive Unit—in fact, with a model identical with the one on the Boeing 707, and completely interchangeable with it. This model is now to be fitted to the Boeing 707's being supplied to B.O.A.C. English Electric can also produce all the rest of the equipment—A.C. generators, including the new brushless type, actuators, motors, control and switch-gear, transformers, etc., prepared to suit any specification. The next generation of civil aircraft can now take advan- tage of the additional safety, reliability and economy of Constant Frequency A.C. Let English Electric do a design study. . . • ENGLISH ELECTRIC aircraft equipment THE ENGLISH ELECTRIC COMPANY LIMITED • AIRCRAFT EQUIPMENT DIVISION • PHOENIX WORKS • BRADFORD MEMBER OF THE ENGLISH AVIATION GROUP
