Just a SWAG but I'd say it's to keep the flow attached to the elevator at h
igh deflection angles. The effect would be more analogous to the effect of
slotted flaps. In this case it is increasing the effectiveness of full up e
levator.

I'm no aerodynamicist, but my guess is that is the critical spot where the
boundary layer needs to be energized, whereas on the wing the critical lift
area is near the front?????
Anybody know the engineering behind the placement?

Subject: MurphyMoose-List: Elevator VG's
Why do most guys put the stab/elevator VG's back at the hinge line (on the
bottom of stab of course) and not more forward like on the wing? Is there
some guidance on this? It seems to me it would be like putting the wing vg
's back just in front of the flaps or aileron hinge? Trying to decide wher
e to put them.
Thanks,
