An operating device for operating at least one door of an aircraft comprises a chassis that is fixed and secured to a fuselage of the aircraft, a control handle that is rotationally and translationally movable with respect to the chassis, a mechanism for converting a rotational movement of the control handle into an opening movement of the door. The translational movement allows the control handle to be in an in position in which it is aligned with the exterior surface of the fuselage and an out position in which it projects beyond the exterior surface of the fuselage. The control handle includes a cylindrical body and a head connected to one end of the body. The head of the control handle includes a fixed part rigidly connected to the body of the control handle and extending perpendicular thereto, and a movable part rotatably connected to the body and having a folded-down position against the fixed part and a deployed position in which the control handle has a T shape.
