Any pireps for PCAS MRX collision avoidance system?

Andrew,

Since mid-air collisions occur near traffic patterns at low altitudes
this is where I would want the system to be most responsive. It seems
as if the opposite is true.


Two points:

1. Except at very remote fields, the likelyhood of airliners with TCAS
being above the pattern is high at most busy GA fields, since they will
be near major cities.

2. In a busy pattern, I would not want you to look at a fancy display
giving you traffic information, I want you to look out.

To expand: My experience with these simpler devices is that if you have
more than, say, two close-by targets (a typical situation in a busy
pattern), they become useless since you'll be busy looking outside. I
turn our voice alerting off on the Monroy in these cases, since it will
just say "traffic nearby" all the time and show a distance of a mile. I
know that already, so I look outside.

These units are great for alerting you at times where you don't expect
traffic to be around, e.g. at that lonely field where it finds you that
one other plane in the pattern you have missed, or during cruise when
you are busy programming the GPS.
