Patent attributes
An aircraft cargo handling system has a pair of load restraining rail assemblies, each of which has a shaft assembly running substantially parallel to the longitudinal axis of the aircraft. The shaft assembly has a plurality of lock pawls, each of which comprises a body having a cylindrical pallet-engaging surface. The pallet engaging surfaces of the lock pawls have increasing included angles at stations moving toward the front of the aircraft (or vice versa). This enables the pallets to be locked in place sequentially by rotating the shall assembly a predetermined angular rotation each time a pallet is loaded. Unloading of the aircraft is carried out in the reverse order, by rotating the shaft assembly in the opposite direction in steps to unlock each pallet individually as the aircraft is unloaded.
