Hi Veloo
I've been working with Thales the past two years, here's what I've found
If it runs completely error free, it seems to be highly effective, some problems though:
1: RADTAGS (impromptu radar tags) seem to disappear for no reason
2: RAM (Route adherence monitor)(I think) goes off for apparently no reason sometimes... Even though the acft is enroute or even only just ariborne
3: It seems, in our airspace, when helicopters get too close together squawking 2600, for some reason they couple and show a squawk of 7600 thus triggering an RCF alarm.
4: Personal opinion, but all the alarms sound the same, regardless of their meaning, I'd like to see some diversity in this regard to channel the focus where needed. especially when you're getting multiple "false" alarms.
5: In the same light, the alarms are also a little excessive, once the alarm goes off, it seems never to end.
6: Last and certainly not least, we experience a system failure about once every two weeks. Down time can vary from 20 minutes, to a couple hours, depending on the problem
Hope it helps...
