Don't you just hate it when a quote isn't related to a name!!!!
MG, you've quoted my explanation about the supply tanks!
The indication may have been 47/43 (lbs) ; low but above the minimum if the indication was in kilos, and base was only a short hop away. However there would actually only be 21/19 kgs in the tanks which of course would not be enough. But of course as you've quoted this you must have already read it!
Maybe with an indication of 167 (lbs) on the main tank display, (but there only actually being 76 kgs in it), the main tank was not a concern and maybe the pumps being off were also not a concern as a low speed portion of the flight was being undertaken at the time and maybe the cautions came on requiring the pumps to be off.
Of course if the fuel indications were in lbs, ie reading higher than actual, and the CAD went u/s what fuel values do you go on?
As I said, just a thought.
(p.s. I didn't say the other quote, ttb!)
