The idea is to let the telemetry values affect mixes, rates, curves, etc, proportionally.
Imagine for example you have a GPS on the model. You could use the speed to control rates for example. the faster the model flies, the more the rates decrease. we would really need a IAS (indicated airspeed) sensor for this to work more accuratelly.
Also another one that just comes to mind, is to deploy flaps automatically according to speed being their angle controlled by how fast the model is flying.
In theory, you could even control the motor channel so the plane would not fly over a certain altitude..
Just a few examples.. I'm sure there are zillion of applications for this feature
