It's not alwaysthat simple, and depends a lot on the construction of
the winch. It makes a big difference, for example, if it has a torque
convertor as opposed to a fxed ratio gearbox or a fluid flywheel. You
need to take account of the tension-speed relationships for both the
winch and the glider.
