Fuel and Emission Savings from the use of Lightweight Composite Unit Load Devices

Abstract

This paper aims to explore the benefits and feasibility of lightweight composite Unit Load Devices (ULDs) as an alternative to conventional aluminum and steel ULDs. The advantages of such ULDs are quantitatively highlighted through determination of potential fuel, cost, and emission savings from the reduced weight of the device. Case studies are performed upon Boeing 777-300ER and 737-800 aircraft through replacement of LD3 and LD7 devices. Analysis indicates that maximum theoretical cost and emission savings of AUD 183,828 and 24.62 tonnes per aircraft, per year can be achieved. The analysis indicates that the potential higher upfront purchasing cost of lightweight ULDs can be quickly offset by the weight savings of said devices.
