Abstract
The door sill of a cargo loading and unloading opening in an aircraft body is protected against damage by a cover plate that is hinged to the loading floor alongside the door opening to be tiltable outwardly to cover the sill when in the operative position. The outwardly pointing edge of the cover plate is supported by a support linkage, including a support link or section and a tie rod or bracing link, which are pivoted to the cover plate and to each other, so that the plate and its support linkage may be tilted into a recessed position in which the plate with its support linkage extends substantially in parallel and close to the door or gate that closes the cargo opening, thereby using very little space in the stowed condition.
