The difference between the two views is only that of whether one believes that such a system was/is necessary
Despite all of the problems associated with TCAS, many of which I was unaware of until now, it has generated a greatly heightened alertness in the cockpit as compared to the pre-TCAS days. In the majority of cases, we didn’t even know a potentially conflicting target was out there.
I think, however, the
fait-accomplis of increased airspace utilization using TCAS as the all-encompassing anti-collision solution is premature.
Clearly, it is not ready for that function.
