52N:
you have been providing a RAS to an inbound, you have transferred your inbound to tower and you suddenly notice a fast moving unknown going towards the inbound, what do you do? For me, the RAS continues for the inbound until the aircraft is on the ground, if necessary I provide a RAS through the comms of the tower controller.
But if said inbound is already sailing down the ILS and probably below the min altitude specified in the final approach area of the RVA, the only action the pilot can take to a traffic warning is a go-around. So it's not really a RAS any more is it? And a RAS-at-one-remove-via-the tower-controller sounds like something ATSSD would be interested to hear more about.
