Dear all,
I was querying some information about TCAS RA and found that thread (sorry for coming back to a rather old discussion).
Last week, flying an A220 level at FL320 within German Airspace, we received a TCAS RA Descend order which we obviously followed promptly.
Once clear of conflict, we returned to FL320 and asked the ATC about the other aircraft.
It was apparently flying level as well at FL330, a northern-american B767 which reported no RA but also no TA.
We were quite surprised to ear that the conflicting traffic could have no RA or TA while we were manoeuvring away.
This thread suggests that it could be possible.
Anyone experienced something similar recently?
Thank you for your feed back.
Regards.
