Ultra Long Haul fuel efficiency
Just reading a bit about this Project Sunrise. I saw this comment from the Lonely Planet founder on Linked In , which surprised me ! Usually the RAS puts out respectable information. Is the quoted 30% extra fuel burn fair dinkum or just juggling of figures ?
”I'd been wondering what that extra cost might be until January this year, when a gathering at the Royal Aeronautical Society in London revealed figures that showed it takes 30 per cent more fuel to operate using Perth as the one stop from Australia's east coast to London (QF9), rather than having a more evenly spaced stop – Singapore or Dubai, for example.
Any comments?
