Navigation table attachable by an arm to the base of an aircraft seat can be folded to a storage position beside the seat when not in use. The table surface comprises the top of a box which can be used for the storage of maps or papers. The box is mounted so that it can be easily removed from the seat and used by the pilot like a small attache case to transport maps and other materials to and from the aircraft. A plurality of adjustments on the table mounting arm permit the table surface to have its surface angle varied in addition to being movable, sideways, up and down and fore and aft.
