SAE ARD 6481

AS8049A currently requires adjustable features on aircraft seats to be designed so they can be returned to the positions required for taxi, takeoff and landing by the occupant without the release of the occupant restraints. This ARD will demonstrate Aviation Industry support for revisions to TSO-C39c and TSO-C127a to allow Technical Standard Order (TSO) approval of aircraft seat products designed with adjustable features that require the release of occupant restraints to return the feature to the taxi, takeoff and landing position.

This ARD will provide the technical evaluation and recommendation to FAA Engineering Division AIR-120 from the SAE SEAT Committee for changes to TSO-C127a and TSO-C39c to allow for approval of seats with a conversion feature (e.g., berthable divans, full lie-flat seats, etc.) that require the release of the occupant restraints to return the seat to the taxi, takeoff and landing position. This ARD will also recommend these same changes be made to the next revision of AS8049.
