TCAS outside of CAS
DS is absolutely correct to point out the fact that the ADN-NEW 'airway' is not a true airway for most of the day. Of course we all know that it will become permanent eventually; apparently certain airlines consider that saving fuel is more important than getting their passengers safely to their destination. All the FJs in their way (doing their job in ever more constricted airspace) do their level best to get out of the way, I can assure you, but class F/G airspace is not an airway.
Bearing that in mind, again I back up DS' point of 'what are you thinking selecting RA outside of CAS'. I take it that this didn't happen during 'quiet hours'. My albeit limited understanding of TCAS in RA mode is that it is only effective if everyone is in the same mode. Unfortunately I don't recall the rules mentioning the difference. Maybe the rules assume a modicum of common sense.....
On the positive side, the mil FJ in that area of class F/G airspace are now required to try to get a service. This will be at the expense of their flexibility and effectiveness but is the best that can be done. They could just stay on the ground and not train......
I suggest that everyone recognises the freedoms of class F/G, which are essential to FJ ops, and either keep a good look out or pressure their companies to confine themselves to CAS for passenger flights, or at least stick to TA outside of CAS.
Pull out the pin and let it roll........
