Sonic Cruiser time advantage
I have lately been looking at Boeing's proposed Sonic Cruiser design and the time advantages that aircraft might or might not bring. I would be interested to hear from anyone who felt inclined out of intellectual curiosity to run through some typical figures and see how they come out - either on the back of an envelope or better still in any nav computer that could cope with the parameters. So for example, what would be the real-world time savings on LHR-JFK, FRA-LAX, CDG-SYD assuming M0.95 cruise (but with realistic TMA speeds at each end) and stratospheric flight levels, versus big twin, A340 or 744 as desired? I'd be happy to hear from you offline or on the forum if it seems sufficiently interesting.
