PS. I wouldn't expect you to take EASA too seriously, but for what it is
worth I have just checked their CS-VLA 959, which holds forth on the
subject of unusable fuel, and it says it must be checked for each tank
in the most adverse conditions likely to be encountered, so the EU is on
your side! David

unusable
fuel and how anyone sensibly manages his fuel. Unusable fuel is pretty much
what it says on the label and this side of the pond its only practical
consequence
was that the LAA want a figure for it and want it included in the 'ready
for service' or empty weight. That apart I am all in favour of gauges telling
the true figure of what fuel you have in the tank. Very few would want to
work out in flight how much fuel is actually useable or not. We all surely
always
operate with sensible reserves. In fact a fair number of my aquaintances have
never had to use the reserve tank and are rightly proud of themselves. In
addition the large majority of my take offs and probably those of my friends are
with a full tank - this partly because much of my flying is touring, doing
longish stints, but also because I still have a linge
ring
memory of being taught that you should always fill the tank before putting the
plane away so as to discourage air cooling in the tank and depositing small
amounts
of water.

make it the most critical attitude. However it only really applies to those
who would contemplate seeing if they can take off with +/- empty tanks. It
seems to me much more practicable to go with the cruise attitude, where I guess
99% of fuel starvation happens. So door sill level would be my recommendation.
