RE: Advantages of an airfoiled stab?
yeh-- actually the lightly loaded wing flies at a very flat angle -with fuselage more or less horizontal - not much if any angle of attack noticable - the so called lifting stab MAY correct somewhat for the tendency of flat bottomed shaped s to zoom as speed increases--- little if any
In flight if you could actually measure it -- the flat bottom of the wing may actually measure as pointing slightly downward- looking like a negative angle of attack-
