No I used used “reducing radio calls” in the context of:
OZBD: "TCAS is last line of defence. It is not the first option to cut out a radio service."
LB: "But I still don’t get your last sentence."
I was simply trying to explain what TCAS is intended and more importantly not intended for. I wasn't putting it forward as an argument.
As I said, you've confused me with someone else who is actually involved in arguing about the topic - you might notice I've made no other posts in this thread.
