March 4, 20251 yr The calculation logic is flawed. Instead of calculating LW = ZFW + EFOBdest the system calculates LW = TOW - Trip fuel and since trip fuel logic is dynamic, as it is contantly recalculated on the fuel page to show how much fuel is required to fly the rest of the trip, it is essential that the calculated LW is going to be higher than the actual GW and what is funny, at the last waypoint LW will equal to TOW. The A350 is a brilliant aircraft. It can land after a 10+ hours flight with keeping its take off weight 😄
