The latest generation of commercial jet transports, typified by the Boeing 757 and 767, is improved over prior generations by the widespread application of new technologies. For example, weight is being reduced by selective use of composite materials, by utilisation of stronger alloys in the structure, and by employment of computer-aided design and manufacturing techniques. Aerodynamic advances in wing design are reducing drag, lowering fuel burn, and allowing higher cruise altitudes. A new generation of engines are providing significant improvements in fuel consumption and noise suppression. But perhaps the most significant of the new technologies, is the extensive utilisation of digital computation in this latest generation of commercial transports.
