Fuel contamination and other basic survival instincts

Actually, it will take a lot longer for all the water to settle to the
bottom. Tiny droplets of water setlle at an extremely slow rate, and even a
small agitation will disturb them back into the fuel. The basic idea of the
sump drain is not just to remove water, but to indicate that there is a
problem with the fuel. Once you detect water in the sumps, it's going to
take a lot longer than 5 minutes to get going.

An Instructor once told me that it takes 5 minutes per inch of fuel in
the tank for all the water (if any) to show up in the sumps. Don't
know where he got that from, but I thought I'd pass it on.
