Del;
What West Coast said, also I have been both in the sims watching the training as well as in the jump seat (back when we could) and have watched it first hand (With VFR's who were 500 feet away, which by the way is perfect separation.). Also we can see that the aircraft hasn't even started the manuver yet when they report the RA... It's a training thing here that we started at the onset... One of the nice things of having ONE aviation authority for a LARGE bit of airspace <G>...
regards
Scott
