After reading the FSX-SDK's article about:

- New Aircraft Procedures:

-> "Getting Started on a New Aircraft"

--> "Aircraft Center Point" (on the DC3 Example)

---> The green box in the image below is the

**aircraft’s center point.**

A - I'm wondering what that "Aircraft center point" model exactly is:

A - I'm wondering what that "Aircraft center point" model exactly is:

Is it just

*a geometrical modeling axis-origin point*(X:0,Y:0, Z:0) of my 3D aircraft shape?

.. which can essentially be put anywhere inside / outside my model?

Does this point also need to be located on the exact

*Center Of Gravity*of my aircraft model?

.. in order to have an correct mathematical effect on the aerodynamics of the model?
