摘要

As the aviation industry expands its support for initiatives to reduce its environmental impact, more countries, airlines and companies are making investments and working together to find ways to meet carbon neutrality targets. When Airbus in November 2019 announced it would demonstrate energy-saving automated formation flight in 2020 using two A350s, and Boeing subsequently revealed it had flight-tested the concept in 2018 with two 777s, it was a signal that a long-known technique could soon be ready for prime time. Air-wake surfing for efficiency has a long pedigree of consistent research results that show an aircraft can save fuel by flying within the updraft created by the wingtip vortices shed by another-reclaiming energy left in the atmosphere by the lead aircraft's lift-induced drag. So why are operators not already using the technique to improve efficiency? And why is it being looked at now? One reason is the availability of the avionics required to enable automated wake surfing, particularly automatic dependent surveillance-broadcast (ADS-B).
