You were taught a very popular myth. No doubt you were also taught the
myth
(spread by Rod Machado and others) that your fuel gauge is only required
to
be accurate when it reads zero fuel.

The myth is that they have to only be accurate at zero. The truth is
that there's
no requirement for accuracy at all. All the misinterpreted rule says is
the EMPTY
mark means zero USABLE fuel.


That is pretty much what I said, except that 91.205 says that you have to
have fuel gauges indicating the quantity of fuel in each tank. However,
91.205 does not say how accurate a gauge has to be to meet this requirement.
I do know from painful personal experience that some FAA inspectors will
write up a plane if they think the gauge is too inaccurate.
