ACAS against unverified SSR
Yesterday I was providing RAS in Class G (I know, I like to live dangerously!) and called a 7000 squawk indicating slightly below, slowly climbing towards my traffic. The pilot rejected my avoiding action, saying he had TCAS contact and was happy to continue.
I breathed a sigh of relief, but being quiet it gave me time to think. Did the pilot know the Mode C was unverified, and therefore unreliable? I asked, and discovered pilot's do NOT get the Mode A data, just the height readout.
Whilst this would have to be verified in regulated airspace, out here in Injun Country it need not... Seems to me another case, where pilots should be using TCAS/ACAS for collision avoidance (as it is intended) and not using it as a tool to maintain separation? Any thoughts?
