A note and a question:

Note: (E-flat) - Most folkes don't take into account that the horizontal
stabilizer also contributes lift to the aircraft. Granted, in most cases
that lift is negligable, but it is there. It is my understanding that much
of the problem with icing on modern T-tail turboprops is because of the
increased dependance on the stab's contribution to total aircraft lift. T?
F? I'm not real sure.

Question: Is it not true that mounting the stabilizer and elevator on the
top of the empannage gives one's design a **slight** increase on moment
arm? I seem to recall a wee increase in leverage, therefore allowing the
fuselage to be a wee bit shorter, and the stab a wee bit smaller, thus drag
a wee bit smaller?
