Stability analysis

[Iven Z]

Hello, I would like to ask about stability analysis in OpenVSP, as the positive x-axis direction in OpenVSP points from the nose to the tail, but in most cases, the analysis is done from the tail to the nose, and the z-axis points downwards. Therefore, I would like to know the sideslip angle when conducting heading stability analysis β How are the positive and negative values regulated, including the aircraft's α The positive and negative of the angle. thanks
