An aircraft cockpit including a viewing device comprising a screen pivotably mounted on a mounting that allows height adjustment. A screen may also be placed at the top central portion of the instrument panel. The central screen is movable between an extended position and a retracted position in which the screen does not block the view of the pilots through the cockpit windscreen. A glare screen cowl, made at least partially of a taut fabric is used to cover the viewing screens, except optionally the mobile central screen which can pass through the cowl via an opening provided for that purpose. An avionics rack may be positioned forward of the screens of the instrument panel, in which the mounting is advantageously also used to support other devices such as a rudder control system and writing shelves.
