Extending flight times by making planes fly slower could reduce emissions from aviation, according to a study from the University of Cambridge. It suggests that reducing flight speeds by around 15 per cent could decrease fuel burn by 5 to 7 per cent. Planes would likely have to be designed in the future to accommodate this reduction in speed. The study also notes that the downsides of this policy would fall on passengers – slower speeds could add up to 50 minutes to a transatlantic flight for example. While just 10 per cent of the world’s population currently flies, aviation already accounts f…
