Another consequential problem is the lack of understanding by ground crew as to the requirement to leave 500kilos in the centre tank.
The load sheet seems to be incorrect 8/10 times. Our requirement is to turn the pumps off when the centre tank fuel gets down to 500k and thus not use it. We therefore require this 500k to be put into the ZFW (which is all explained before we start). Another problem is the addition of fuel. We supervise the 'dialling in' of fuel before uplift begins as we kept ending up with 500k more than required!
