Device for positioning the cockpit rose of a frontloading freight aircraft. The invention concerns a system for simplifying the air transport of large volume loads. It consists, without involving any alteration in the design, in lowering the cockpit rose (1) below the loading plane (2) by means of an interface module (5). This configuration releases the front upper portion (3) in order to form an adequate opening (4). The interface module (5) restores the physical link between the cockpit rose (1) and the lower portion of the front body (8). The device according to the invention is especially suitable for the transport of aircraft sections to feed a production chain.
