addition, modern winches are constant tension with computer controlls that
prevents the winch from applying enough force to break the weak link.
Interesting facts - does such a winch actually exist?
I have to admit that I haven't seen any winch with such a computer
control yet.
Bye Andreas
In our Club in Herning Denmark we have a 25 year old Diesel Electrical
winch, controled by an industrial controller.

Prior to launch the maximum wire tension is preset according to aircraft
type, and the rest of the launch is basically automatic.
The Pilots controls the airspeed via. pitch.
I would assume the winch has accumulated something like 100000 starts.
