Payload/rwy calculations

Hi Sami,

In MT my A350s aren't performing as promised on IA268 MDQ-CDG and IA276 AEP-CDG. This was also the case for the A340-600HGW. So I am currently running into this issue again with my very expensive A35Ks, which I bought for this purpose.. Would be really nice if this could be fixed as I am/have missed a lot of revenue over this issue...
