Wait until you see what the Airbus does !
Longer runways, always goes for incresed V2 which drags V1 up with it. the number of times we look at remaining runway at V1 and go - Naaaah, that wouldn't have worked !
Don't always but blind faith in the V speeds either - we had a certain desert destination where luck features a lot - back in 2001, our perf people omitted the aerodrome elevation of over 2,000' in the perf calcs for a whole season !
They were interesting departures
