........and if I may resurrect this one by asking you perf experts how much margin has been taken away from us with the advent of the laptop calculation of performance (Airbus) compared with the old RTOTs where minor details such as the headwind -ignored - and temps - rounded up. Are we we really looking at clearing obstacles by the regulatory minimum - if that's the limiting regime we're in - assuming EO at the critical point? If so, to quote Sgt Wilson; ''Do you think that's wise?''
Thank you,
