Aircraft are more energy efficient than popularly supposed, and have the potential for a 75% reduction in Btu per passenger-mile. Improvements would come two ways: operating present aircraft differently, and applying advanced technology to future aircraft. No larger aircraft (400 or more passengers) has ever been designed to serve the short-haul market now dominated by ground modes. An aircraft specifically designed for this market would have greatly reduced energy consumption. Advanced technology aircraft incorporating supercritical aerodynamics, composite structures, improved quiet propulsion, an active control systems would likewise have reduced energy intensity (EI). The dominant role of load factor in measuring aircraft performance reveals that present values of revenue EI result more from the way the national aviation system is operated than from physical attributes of the aircraft itself.
