A reasonable thread for a change. Here's my 2c worth:
The fuel dumping scenario is even more complicated than A388 pointed out. The aircraft tends to fly at fairly aft CG positions - 41% in the cruise is not unusual. This means that there is a fair amount of fuel in the trim tank (THS).
While
theoretically it is possible to dump all the fuel except the feed tanks, in actual practice the CG limit is reached with fuel still in the trim tank. this leads to a very puzzling ECAM that doesn't appear to be connected to the dumping going on.
End result you will probably land with feed tank fuel
plus trim tank and a very interesting CG position.
The Overweight Landing check can be conducted 'remotely' by MCC but this requires a fairly large data file to be downloaded off the engineering PC and transmitted to Base. No procedure exists to accomplish this task - you'll have to wing it on the day.
BTW the aircraft lands beautifully at 450 Tonnes
