I find it weird that apparently noone considered, that on the way back to base G-SPAO's CAD looked exactly like Figure 11, p.53 (G-NWEM during test) of the final report:
a) Both supply tanks indicated as full,
b) the main tank is seen gradually draining,
c) yet the LOW FUEL 1 and LOW FUEL 2 warning light comming on, time and again.
a) + b) are exactly what normally would happen,
when fwd. xfr pump is on, as I'm sure it typically was on other flights.
When presented with such grossly contradicting information
one might easily tend to trust the graphics and
regard them warning "lamps" as faulty.
