In September 2004 issue of AOPA Flight Training, Mark Cook has an article,
"No Fueln' Around". Under the "Selector boy" side article, he mentions
that he runs some of his tanks dry in his Bellanca Viking. In at least
one of John Deakin's articles
(http://www.avweb.com/news/columns/182044-1.html), he not only recommends
running tanks dry but puts forth a powerful argument that it's a
responsible fuel management strategy. Furthermore, Deakin also offers
that he has never found an NTSB accident report related to a failed engine
start when running a tank dry and switching to the next. Both guys
recommend setting a timer a couple of minutes before the tank should run
dry; which acts of both early warning and as validation of your
anticipated fuel consumption.

Is this common? How many run their tank(s) dry as part of their fuel
management strategy? If you don't run dry, why not? Aside from the heat
beat skipping which is sure to follow the first couple of times, what's
the down side to this strategy?

Lastly, I did cross post this message as I feel it's of value to both
student and general pilot population alike.

Cheers,

Greg



The Ercoupe had it right. Both wing tanks are pumped into the header tank behind the engine in front of the pilot.
Excess fuel is routed back to one of the wing tanks (right side?). Gravity feeds the engine. When all of the fuel is
gone in the wing tanks the header tank bobber starts to go down; leaves something like 5 gallons available and you know
you used up the mains and you have about an hour left...
