I rely heavily on the fuel totalizer in the
Velocity. On refueling, it is invariably accurate to within a gallon on a
30-70 gallon burn, but there is one scenario where reliance on the
totalizer can leave you in the lurch, and a bad one at that. If a leak
develops upstream of the fuel totalizer sensor, or you leave a fuel cap off, you
can be draining or vacuuming a large fraction of your fuel overboard, but the
fuel totalizer does not recognize this loss, nor will you, if you rely only on
the totalizer.
Accordingly, we need a means of sensing, or
directing reading of, the fuel left in the tank(s) to know that we haven't had
an unexpected loss and that we can rely on the fuel totalizer.

Mike,
I fly an ES with close to 600 hrs on it. Each time I fill up I
check the actual fuel pumped against the fuel computer and invariably the fuel
computer is accurate to within 1 1/2 gal. max. I trust it much more that
the fuel gauges. I only use the gauges to balance fuel load in
flight.
I do cross check the gauges against Fuel Remaining and Time Flown just
for comfort.

Subject: Re: [LML] Fuel Planning
I mentioned earlier about the "mental math" I
do to confirm that the time, fuel flow, fuel level numbers match up. I
pulled up some of my JPI flight files and compared the fuel level changes to
the fuel flow number and they matched up very well. So my mental math
and data confirm the current accuracy of my fuel gages. My experience
is the fuel flow transducer is a more accurate tool than the fuel level in
determining how much fuel has been used out of a full tank.
Anybody have comments either way on fuel flow
transducers?
