Optimum CG Range

For the ASW-28, and probably other modern gliders, the "manufacturer's
approved CG range" is dependent on the glider mass.

That's not just for modern gliders and not necessarily connected with the
amount of ballast on board or the pilot's weight.

The Libelle 201B handbook contains a W&B diagram on page 6 (of both
German and English sections). This shows that the GC limits for the
aircraft move forward as its empty weight increases.

I don't understand why this would be the case - just that its documented
in the handbook.
