The Macchi C.200 was a modern all-metal cantilever low-wing monoplane, which was equipped with retractable landing gear and an enclosed cockpit. The fuselage was of semi-monocoque construction, with self-sealing fuel tanks under the pilot's seat, and in the centre section of the wing. The distinctive "hump" elevated the cockpit to provide the pilot with an unobstructed view over the engine. The wing had an advanced system whereby the hydraulically actuated flaps were interconnected with the ailerons, so that when the flaps were lowered the ailerons drooped as well.
