This Aerospace Recommended Practice aims at providing general utilization guidelines and calculation methods adequate to guarantee the effectiveness and ultimate load strength of tie-down/lashing arrangements performed to restrain cargo on board civil transport aircraft during flight:
a. Cargo loaded and tied down onto airworthiness approved air cargo pallets, themselves restrained into aircraft lower deck, main deck or upper deck cargo systems meeting the restraint of air cargo pallets approved in accordance with NAS 3610 or AS36100, or
b. Additional tie-down on aircraft structure when necessitated by pallet maximum gross mass or centre of gravity location, or
c. Individual pieces of cargo, or pieces of cargo placed onto an unrestrained (“floating”) pallet into either lower deck, main deck or upper deck containerized cargo compartments of an aircraft, or
d. Individual pieces of load loaded in non-containerized (bulk loaded) baggage or cargo compartments.
Revision B was developed to take into account the changes to AS36100 and AS36102 revisions B, including introduction of straps tie-down testing on pallets, as well as recent changes in approved aircraft Weight and Balance Manuals.
