> Airlines would save 90,000 gallons of fuel on average and reduce emissions by 27,000 tons annually, which is equivalent to the amount of fuel used by 62 Boeing 737 flights between New York and Cleveland — or the annual carbon emissions of more than 1,600 average Americans combined.
Close to negligible amount of carbon savings, but maybe the noise justification is more meaningful.
It sure isn't done to help the airport neighbours, they're not that altruistic. It's likely a negligible carbon savings, but their concern no doubt is saving a penny wherever possible, including the fuel.
You mean like how we were taught to land at flying school?
