That is my guess as well, based on the information from the seminar.
As I understand it, the G1000 would disable (red "X") the readout of
any component with an unresolvable conflict. Since the aux tank was
"refilling" the main fuel tanks via the overflow return, it wouldn't
be long before the flight computer data would be in conflict with
the fuel level sensor and therefore generate an unresolvable error.
It should be expected that both displays would show the same error
condition.

I guess that would be based on the invalid presumption that the fuel
computer, time to empty, fuel flow, etc have any interaction with the
fuel level indicators.

Yes, that would be it. ;-)

They don't.

Thanks for the clarification, as it is not the answer that I got to the
question I asked about it. But, as you apparently own one and have
observed this condition, your knowledge resolves the conflict. ;-)

So, what happens if the fuel level indicators report "full" after a few of
hours of flying, which could be the case in NW_Pilot's ferrying scenario?
Might the GEA presume that they weren't working, and "X" it out on the
display?
