Wing Shape Irrelevent

The loads talked about in this post (85T and 105T) would both result in full wing tanks, so the talk about funny shaped wings is irrelevent.

The wings hold about 10,000 Gals eash (approx 30T depending on density).

The fuel probes (in any technology) actually give a height of fuel above the probe. This can then be converted into a volume, and then the actual measured density will be used to convert it into a mass. This is all fairly straight-forward when all is working, but if one probe is mis-reading it starts to get complicated. Computers are not very good at looking at a set of data and saying "that reading is silly, let's ignore it"

The bowser will also give a volume reading, which is converted using the fuel farm density to give a mass. I guess if the bowser is parked out in the sun fully loaded for an hour, the temperature of the fuel could go up, and hence the density of the uploaded fuel will be lower than that reported at the fuel farm.
