Actually, we do not know this. We can assume it, and the evidence is
pretty strong, but there might have been other factors which we
don't know.
True. In addition to the fuel sensor "overload" (it didn't really
fail -- it just sent info to the G1000 that made no sense), he also
experienced a CO sensor failure, and (later) a tach failure.

It's hard to say what caused what to happen, without more data.

I agree that we are in no position to determine the cause of the
problems;
they could be specific to this particular unit, or caused by damage
during
the installation of the ferry tank and other panel mounted items rather
than the general design of the G1000. However, it still troubles me that
Garmin told NW_Pilot that the system can experience similar problems
during stalls and in slow flight. That *does* sound like the G1000 has
some design issues that need sorting out.

I just went back and reread his account. ( I'm not flaming Steven but if
you've read his emails before you know that his written words can often be
difficult to read for content ) He said that the fuel readings went to
red Xs ( as a properly designed system with a out of spec sensor should )
after flying ( and venting excess fuel for 7 hours ) Then he got a CO2
warning then a GPS-1 failure. It was after the GPS1 failure that the unit
rebooted. Now failure of the fuel system I would not want a reboot for
but in some situations failure of the primary navigation system may be
grounds for a reboot depending on what failed. After the reboot completed
he was missing readings like fuel and airspeeds. He mentions other errors
but does not say what they were. He does not specifically say that the
system rebooted again directly. He said in summery it was continually
rebooting but I question that. Steven - Was it rebooting or did it just
reboot once after the initial failure? He mentions that on downwind the
fuel readings were working again but then failed again during turn to
final. Did the sensors starting given valid information after the fuel
burned off enough to have then in range and then fail again during the
turn? Not sure. He does mention the G1000 rebooting again during his
landing. Was this the second reboot? Did other instruments fail again?
Too many questions and not enough information to say for sure.


Will solve this question, It had to many reboots to count! The unit would
reboot then start showing items failing then reboot again start showing
items failing then reboot again and again for a few hundred miles! After
each reboot it took about 10 to 15 min to reboot again. The fuel sensors
starting given valid information upon the reboot after landing and I still
had Co2 and GPS Failure On Landing and airspeed was still a Red X! I only
took note of the critical errors I tried my best to document them all but I
am not superman I still needed to fly the plane.
