Ed, your getting close to making sense for me.

John, you are correct I meant stab. And your comment about "it could" seems correct also. But nobody, and I mean nobody, says what to measure it against on an ARF. The manufacturers and cabitzers all talk at great length about setting it at "x" ; but I have yet to have them say "x" to the stab, or "x" to the fuselage bottom etc. So it seems to me this entire incidence thing is probably way overblown. Am I correct.
