The trailing edge had simple flaps inboard of the nacelles and large ailerons outboard; the outer flaps were to incorporate air brakes, but were replaced with split-brakes prior to the first flight. Both the flaps and air brakes were operated hydraulically, with an independent system for emergency actuation.
