I use the FAA regs that say to plan the fuel from departure to desitination at normal cruise ( calculating for winds aloft, of course ) then to alt
airport plus 45 minutes for flight. http://www.risingup.com/fars/info/part91-167-FAR.shtml. Pretty cool site if you are at all interested in real
world flying. They have the FAR/AIM on line and practice written tests for private and instrument. Somebody on this forum showed it to me a few days
ago. I don't remember who,though.
Using this formula, I've had zero in real life or sim.
Although, one time when I when to rent a plane
from my flight school the fuel guages were on E when I did my pre-flight. The lineman put in 24 gals in the 26 gal tanks. That means there was less
then 1 gallon of useful fuel in the tanks. I'm thinking that Cessna says that there are 1.2 gallons of unusable fuel in each tank. The Cessna 172
burns 10 gallons an hour at cruise so you do the math to see how close they were to running out of fuel. And when the owner of the aircraft was
informed by the lineman he went balistic. He was yelling when I left on my lesson and after two hours was still yelling when I came back. I don't know
what he told the renters but the next lesson my instructor had a round table with all his students when over fuel planning first thing for everyone he
taught.
