Full fuel payload is a critical benchmark for measuring the utility of any
aircraft.

So if I get tip tanks for my Aztec (which I'm considering right now) and
increase the amount of fuel I can carry by 44 gallons, the utility of my
plane goes *down*?!

If you can carry a larger payload with full tanks, you can obviously carry
that weight farther than the poor guy who has to leave fuel on the ground.

How much would you pay me for an STC that blocks off part of your fuel tank?
