Affirm Brest - interesting, everday's a school day!! All good stuff but as for the MCT being lower, I'd be suprised (in our operation anyway) as flex tends to be 50 degrees ish all the time, but I'll have a think!!
As for MCT isnt it a max power setting only (not a specific one if you see what I mean) and so A/C will fly any selected speed up to that which is the maximum with MCT... Affirm??
PS my previous post was supposed to be a smile and not a wink but nobody seems to have been offended anyway!
