I have tried the weight and balance feature and i was suprised to find out that you can add fuel and payload but when flying the plane (B737 and A350) the fuel Usage in a350 is shown but its not deducted from the FOB and with the 737 the fuel on Board remain as you added in W & B module, could this be a bug or is this not implemented. yet because i dont see why they could add W&B and yet its doesnt work
