These are all good points.  However, in the LNC2 header tank, at least, I 
would find it hard to believe that the unusable portion would be much above 1 
gallon.  

Still, the tests you suggest are prudent -- perhaps a first whack would be to 
do it on the ground.  But I've gotta believe that the header tank with sight 
tube offers more certainty in remaining usable fuel than with a wing tank 
with any other metering device -- once you establish what is useable and what 
is not.


<<Now you are looking at only the fuel remaining in your header tank as the
 total available fuel to get you from where you are to a suitable airport.>>

Let's see, suppose we refill the header tank when seven gallons are 
remaining, and the wing tank runs dry.  With an LNC2 you can probably go over 
100 miles.  Not a nail-biter, at least to me...- Rob Wolf
