But what matters isn't what you or I happened to be taught, but rather

deal of sense, for the reasons just given.

I won't argue with that statement. I was simply taught that aircraft fuel
gauges are chronically unreliable to the point that they should be ignored,
and that they should never be considered "working".

I think that's half-right, and the half that's right is very
important: you should never trust fuel gauges when they say you've got
MORE fuel than you calculate. But if the gauges say you've got very
much LESS than you expect, you should be concerned. And you need to be
checking the gauges frequently, so you can notice if that occurs. (And
of course, you can only do that if the gauges are operable, as they're
required to be.)
