A350 ISAFTM
When performing part 2 and 3 of the ISAFTM A350 Airbus recommends a fuel load of 50 T.
What is the logic behind this.
For the A330 the recommended fuel load is 45 T. This has to do with the fuel transer logic to/from the trim tank.
Since the A350 doesn’t have a trim tank the recommended 50 T is not clear.
