to manufacturers' specifications. When Deakin comes up with hard evidence
that applies to anything other than GAMI's special setups then I will
welcome it. If there is anything that drives me up the wall, it is these
vague references to "historical operating practices." It is really just a
substitute for "bull****."

I don't have fine details of how one operated piston engines in the
1940's,
1950's, and 1960's. However, Deakin refers (IIRC) to how one *had* to
operate
R-3350s to get anything like acceptable range, and that was LOP. Right
there
in the manuals the flight engineers were guided by. At least, that is my
understanding.

He also sells those nice "coffee table" caliber books that were originally
published by Wright and some others. He refers to them a lot.

$235 for the set of five, most importantly, ' The Aircraft Engine and Its
Operation'.

Think I'll pick up a set.
