Anecdotaly, when I flew the 400 or so miles to Skye with an 115 kg
passenger (18st 3lb), I couldn't detect any significant effect on
cruise OR efficiency (from a one up load). My figures have always
been fairly consistent. I would have thought differently.
Maybe it's just lost in the noise. Practice may be different from
theory.

PS. Except that I'm getting a little faster over the years. Perhaps my
aim is getting better !

Rob:
I agree with you in principle, but practically speaking 5 extra
pounds is not going to register any change in cruise at high weights. And
yes, the airlines do make these amazing discoveries. Mine banned smoking as
a community service - your health is important to us - BUT 200 aircraft in
one year saved $1 million because of the permitted reduction in cabin flow.
What a wonderful surprise!!
