The aeroplane was designed to use a new loading system that can use two different ways of holding cargo : containers or pallets ( either smaller side by side pallets or larger single row pallets ) .
The freighter introduces a new main-deck cargo loading system , capable of accommodating both containers and pallets . The main deck can accommodate different cargo combinations , taking up to twenty-three side-by-side pallets , or an optional single-row ( SR ) loading of sixteen SR pallets and\/or nine AMA containers with the installation of optional secondary structure .
