A Voice in the Wilderness
Maybe I'm looking at this too simplistically, but from a VFR PPL point of view, we rarely ever use Flightwatch because either we didn't need it or couldn't raise it. The amount of extra work that would be transferred over to controllers is negligible because largely they're doing Flightwatch's job already. We have to go to the controllers now.
The question we should be asking is: how much work are the controllers currently picking-up because VFR traffic can't raise Flightwatch? Only by answering that question can we measure how much the service (not the frequency) is really needed.
