A tension controlled winch will do the opposite - decreasing power in
thermals letting lift do the work and increasing it in sink leaving
the pilot to control speed with pitch. The pilot sees a very smooth
launch regardless of wind or thermals. The winch operator doesn't
need to do anything at all.

It's wonderful to never need speed signals again.


.... 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.
