I once had a car that would cover four hundred miles without refueling. That's about six hours on a interstate highway. I did drive it that far without refueling once. But as an everyday action four hours is a long time to sit in a luxury car. Four hours in a light plane is an ordeal. How big is your bladder? Does anyone on this list ever or regularly fly their XL or 701 more than four hours on any leg? If so how often.
A standard XL carries at least twenty gallons. For some reason I am thinking it may be twenty three gallons. I really do not remember. I do not think that any of the popular engine choices burn more than about four gallons an hour. Using that data we should get at least five hours of cruise as a general rule. Of course it would be fool hearted to not to allow for a reserve. So lets say we have four hours to cruise and can land with a more than generous reserve. Unless we have been in a two hour bank neither tank should "suck air" either.
So why not just plumb all the tanks together. Put one shut off valve in the cockpit. This way we can save some time,weight and money. Then plan your flight so that you land with at least thirty minute's of fuel. If that's not enough add a couple leading edge tanks and plumb them in with the rest as well. It just sounds simpler. In my not so humble opinion this simplistic approach would breed far more safety than any possible valve arrangement.
I would love to hear some realistic feed back to this simplistic approach. I am not an expert on fuel management but I think I am going to do this on mine.
