CS,
Thanks for the picture. It is interesting that the side view and the table show arms forward of the datum as negative and yet the chart shows the arm as positive!
I've recently been teaching W&B in a glider ground school and have found similar inconsistencies in glider handbooks. It's stuff like this that makes what should be a relatively straightforward topic, more complex and error prone than it needs to be.
However, as I've said before, in my time at UBAS, W&B was never mentioned, so it wasn't an issue!
