Hi,
A tension controlled winch will do the opposite ... yet thousands of clubs in Europe with much, much more winch experience than any club in the US don't see the need for such a system. Some do. When I was trained as a winch driver I was taught to judge cable tension and use that as the input parameter to the control loop. The only way of doing that without special sensors is to look at the cable sag. Works during the main portion of the launch, but is not very accurate of course. I think if the winch, or winch driver, has the means to control tension and the pilot controls airspeed winch launches become more efficient and even safer. Reports suggest that, I have no experience of my own. Also you would propably get much more consistent launch performance across different conditions and much more important, different drivers. Today we get launches like being shot from a carrier deck and the lumbering wingrunner-testing type all in the same day depending on who is manning the winch. The first launches of the day, or after a driver swap, or when conditions change would no longer need to be different than those by a well-adapted driver. I am all for it. Ciao, MM |
