Change the default coordinate system
While creating a payload, a business user must define a value for the Center of Mass (CoM). This value can be CoMx, CoMy, or CoMz based on the specified longitudinal axis.
You can set the longitudinal axis for an excursion diagram by using the WNB0_CoordinateSystem preference. You can use this preference to define the mapping between the coordinate axes (x,y,z) and the longitudinal, lateral, and vertical axes. The value for the longitudinal axis in the preference is used in the column header. The default value is X.
The following image shows some sample values specified in the WNB0_CoordinateSystem preference (image not reproduced here).
