I've seen this comment widely. But...why doesn't TCAS show the pilots at least as much information as I would have seen on my phone if I'd been browsing flightradar at the time? It's one thing to design a system with "don't saturate the operator with audible alerts" but another to say that it's appropriate to withhold very valuable information from the operator ("there are loads of planes in the general vicinity, but yeah look at that one coming at you from the left").

the TCAS data would have been displayed. but not on instruments or in any place that you typically pay attention to the most during final visual approach (ie., mostly outside).
