JAL Cargo announced that it has started to use 480 new light-weight cargo containers on its international routes. The new ULDs weigh 58 kg, 41 kg less than the old aluminum containers. They are made of synthetic resin in a honeycomb structure which gives them greater strength and flexibility than the old design.
A maximum of 44 containers can be loaded on B777-300ER and with this load the aircraft is 1,804 kg lighter than it would be with aluminium cargo containers. Fuel consumption can be reduced by as much 800 litres for a one-way trip if these new containers are used on the Narita to New York route. Additionally, the durable materials will also reduce the frequency of repairs, improving cost efficiency.
