This video was shot in a Cessna 206 taking us to a game reserve in South
Africa. Watch the fuel gage in the upper right corner.

This is typical for a Cessna and a few others where the fuel gauge uses
the same technology as a toilet tank float.

A fuel totalizer is a very nice thing to have.

Float-type sending units are, in fact, simpler than toilet tank float
valves, and more reliable. They work reliably for decades. However, many
have been in service nearly forty years. Eventually the resistance winding
will develop spots where the wiper doesn't make good contact, and the gauge
(U.S.) or gage (Brit.) will fluctuate wildly for a few minutes, until fuel
is burned off and the wiper moves to a new location, then the gauge works
normally again. Simple and relatively simple to fix.

Do you believe fuel totalizers are more reliable? Or capacitance systems?
Do you trust totalizers totally?
