Coordinate System in FAST

Hi again

Concerning my first question with the right coordinate system in case of upwind turbine, rotor rotating clockwise, I have found in this topic [url]upwind and downwind turbines] , that no matter if the turbine is downwind or upwind, the coordinate system does not change.

Having this information, I return with another question regarding the sign of the Forces affecting a blade in case of an upwind turbine. Is the following correct?
X axis - positive Force
Y axis - negative Force
Z axis - positive Force

Thank you!

Best regards,
