Tcas
Hi folks,
I'm a tower ATCO in continental Europe.
After a series of incidents we've had a refresher concerning TCAS and its performance.
The main message was: with the XPDR onboard a VFR aircraft (light types in most cases) set on ALT - however no TCAS - a RA is created in the airliners cockpit. To my knowledge both aircraft have to be TCAS equipped to generate RAs.
If one of the technologically experienced could shed light on that matter, please ...
Thanks in advance, FR
