Hi John

I understand about the 3 things relating to each other ie thrust, wing, and stab incidence.

Can you explain further on how to get the fuselage level accurately from nose to tail (pitch axis) and wing tip to wing tip (roll axis) before one start to work on these 3 component mention? Tips and approach?

Having said that if you know the FRL and the engine thrust (down and right), I presume the main focus now is the decalage of stab vs wing and the wing incidence. Thats it?
