Genghis,
Talking of crosswinds...can you tell me on what basis (vis-a-vis x-wind) the Vmcg is calculated in CAA regs. Does this differ for the US and if an A320 were operating in the US, for example, do AI change the performance or just accept the appropriate degradation by using x-wind figures.
I ask because a long time ago I was involved with the L1011-500. If we were operating off short strips, under CAA regs we could de-rate the engines to 22B thrust and because of the reduced Vmcg thereby lift a lot more weight from the runway. If memory serves some 10T more! The US registered -500s had different Vmcg figures and did not suffer such large problems, but it was then decided to operate to UK regs.
Our 321s can be Vmcg limited and I was wondering if there had been any changes since the 80s.
Thanks a lot.
