Exsp33dbird - The whole point is that there isn't such a simple 'ballpark' figure on this aeroplane.. With the 'coming' of the laptop optimiser the tables with the 'about right' figures went out of the window
One day you can put in the figures and get a flap 3 take-off, the next day same sector and a couple of minor variables and you've got a 1+F setting - and all with differing flex and speed settings. The performance is OPTIMISED - unlike my last type which had set speeds for set flaps at set weights..
There is no planned EPR setting as such either with the RR Trents on this aircraft. You put the calculated flex into the PERF page and let the FADEC work out how much EPR to set... Again - no ballpark as such..
