What was meant was that it takes more
than simply the land you lift off from to include in the total
distance needed to take off.

Gee. I hadn't thought of that. I guess that whole category in the
performance section of my plane's POH has something to do with how much
distance it takes to achieve a certain altitude then, huh?

I can't tell whether you are being sarcastic by now, but (in case anyone
who's not a pilot is still listening; pilots know this) most POH's do. Mine
tells me the distance the ideal plane requires to break pavement, and in
addition the distance to clear the proverbial 50 foot obstacle. Perhaps
that's what Farlang had heard of.

But I admit I really don't know the difference between "land you lift off
from" and "distance needed to take off" because as far as I know breaking
free of the pavement is legally taking off. Unless there's something weird
about ground effect that I didn't know.
