Airlines could save fuel and reduce emissions on transatlantic flights by hitching a better ride on the jet stream, new research has shown.
Scientists at the University of Reading have found that commercial flights between New York and London last winter could have used up to 16% less fuel if they had made better use of the fast-moving winds at altitude.
New satellites will soon allow transatlantic flights to be tracked more accurately while remaining a safe distance apart. This opportunity could allow aircraft to be more flexible in their flight paths, in order to more accurately follow favourable tailwinds and avoid headwinds, offering the aviation sector a cheaper and more immediate way of cutting emissions than through advances in technology. Current transatlantic flight paths mean aircraft are burning more fuel and emitting more carbon dioxide than they need to.
The scientists found that taking better advantage of the winds would have saved around 200 kilometres worth of fuel per flight on average, adding up to a total reduction of 6.7 million kilograms of carbon dioxide emissions across the winter period. The average fuel saving per flight was 1.7% when flying west to New York and 2.5% when flying east to London.
