OK... I'll buy that. My experience with performance charts is with a 172
and
a PA-28. The latter is sorely lacking in much relevant detail. I would
imagine much
more precision and other ways to figure how to eek out the maximum poop
from your
Helio POH... that's what the plane's FOR!

My PA-28 book makes no distinction. Just says, "Max effort, 25 degree
flaps
over 50'" It might not matter, but I don't info one way or the other.

Actually the Helio manual is abysmal compared to the MU-2 manual which I
attibute to the age of the Helio (1974) to the MU-2 (1982). The Helio
manual does devote a lot of space to STOL techniques though. Manuals keep
getting thinker and thicker as time goes on...the FAA and lawers love paper!
