Some questions about the suspension system.

When the aircraft is suspended, the wing incidence has to be that which is designed for flying, Correct? How is that ensured.

If the airplane is suspended in a nose/tail down attitude does the CG pointer still point to the correct CG position?

The CG of the airframe is a function of the mass of the airframe. The flying balance point is an aerodynamic function. Are the two in the same location?

I am seeking information. I am not trying to decry the method.
