Many years ago.... In a galaxy far far away... Oh wait wrong forum
Seriously. I don't remember if it was somebody like Don Lowe or who but they "said" they took the anhedral out of their stab and lowered the stab by the median amount of the anhedral, the plane flew the same. Simply put. If the tips of the stab drooped by 1 inch, stab was made flat and then lowered in the fuse by 1/2 inch.
Supposedly action this had the same effect as adding anhedral. It was said the vertical location of the stab was the biggest factor in the aerodynamics of things.
Now I may be wrong as this was in reference to what we call "classic" pattern today. Might be a whole new ball game with the modern ships.
