It would be child's play to make a chart that says "when the temperature
is
'x' and the altitude is 'y' your runway must be 'z' length" for each
aircraft type. In fact, I'm surprised that this isn't a required part of
the POH.


This post after you so strongly advocate AGAINST rote learning? You don't
make
sense!

Keeping a simple chart in the plane, versus trying to teach someone the
difference between "pressure" and "density" altitudes, and how to compute it
on the fly?

Makes sense to me.
