Thanks for the AF447 specifics, HN39,
I am reminded that the 25 kts envelope I was thinking of has MMO at the top end and VLS at the bottom. At this late hour (and the wretched clocks about to go forward from real time to big-brother summer time here) I'm not going to try and look up the definition of VLS in the cruise; but it is way above the 1g buffet, of course. Of the order of 1.3g?
Thanks for the AF447 trop figure, mm43,
It's remarkably low for the tropics, considering that the standard atmosphere uses 11000m (36090ft) -56.5C, (and tends to represent temperate latitudes) - almost exactly the same. There could have been a very big step-up at the frontal ("ITF") edge, I suppose?
