It's just the same out here in the Land of sand, sitting on the stand SDT-30 the ZFW is given to us over the radio and we adjust the fuel load accordingly.
However, we can load more fuel if it's deamed operationally required, ie weather etc.
It does get rather stupid though and it depends who's doing your training, some people adjust it and reduce by even 100kg!
Then some bright spark comes up with the fuel saving idea ( about an egg cup full) of not starting the APU as you taxi in until you are about 2 mins from the stand...great.
Then they leave the APU running all bloody day while the A/C sits at the gate!! That makes sence then.........NOT.
Keep dicovering
