Gaunty (just quickly): Riddle; TCAS is designed as a back-up for when the system fails. There has already been heaps of debate about using see and avoid as the primary means of sep, and a lot of that apllies to TCAS as well.
AND;
Same direction, similar speed traffic is very easy to acquire visually (and visual sep is a great standard, predicated on having
first aquired the traffic visually ) You will note the controller didn't say "overtake your co. traffic, and see if you can see him, he's there somewhere", did he? Do you understand the the significance of the difference? Crucial to the debate.
AK. You have in fact stated on this thread that you believe NAS without ADSB is not good.

Basically, if it ain't free it ain't happening and then you'll be stuck with NAS without ADSB below (say) 10,000'. That would not (in my view) be a good end solution.
Why then aren't you predicating NAS on ADSB?
Further, why aren't you opposed to this incremental implementation approach? Their plan is to drive the change, one little piece at a time, as the individual pieces, in isolation, aren't too unpalatable. As a whole, they suck. That is why they are doing it that way.

My opinion is that NAS and ADSB are intertwined
They
are not intertwined. Perhaps you should be opposing NAS until they are?
