Explanation for why power requirement increases with altitude for the

Drew, I think you are not looking at the big picture.Read section 7 of
Denker's material again.
You said "this author comes up with the right
answer, but he uses some false asumptions.Its obvious he hasnt spent
much time in a real airplane". The latter part I find rather insulting
of the author, but I will leave it at that.
I dont think Alice was trying to unsult the guy.You should understand
that Denker is not an aerdynamisist by schooling or by trade, he is
just another pilot like you and me who has read the same books you and
I have.Denker could do a better job of relating how many of his
theories and formulas relate to the actual operation of an aircraft
(He could also stand to correct some of his terminology errors).This
is where the experience level plays in because more real world
experience might help the relevance of his material.

You can't just claim that something is wrong without providing an
explanation. That's what a troll is.
I think all Alice was trying to do was provide some insight as to why
airliners cruise at high altitudes.All you have done is post insults.
