Despite purging a CFP closest to its departure time, i've noticed that the wind vectors and accuracy are completely inaccurate.
Whilst i'd like to consider a 10 Knot variance and a 15 Degree vector as the standard "bias", would I be too naive in considering that is the best that systems can come up with?.
Actual winds usually are completely difference on FMC and my concern here relates to fuel burn, because the CFP defines the Fuel uplift figures and i've noticed actual langing fuel, without hold is much lower than the CFP.
I'd really like as much information as possible on this.
I've been given to understand, we currently use SITA; but separately, i've heard that NAVTECH, FlygPrestranda, LIDO, AIMS and ARMS are a tad more accurate as they factor more realistic scanarios.
Many thanks
