If the TCAS units onboard the A/C "talk" to each other then they mus tx information can this info not be recived and displayed/intigrated with the radar display or is this to far fetched ????
This would enable the controller to be alerted to the TCAS RA and to " keep his mouth Closed??"

Not that simple. Omni antennas do work, but with a range of 40 Nm max, many RAs are false RAs, and there are a few other problems.

Keeping controllers quiet is also not the miracle solution.

Remember that in Ueberlingen , and in all the other close calls resulting from a contradiction betwen RAs and ATC instructions, the ATC instructions were just BEFORE the RAs or at the same time....

Humans and automation do not mix well. The more I learn and known about TCAS, the more I think the only way out is to link it to the Auto pilot.
Until we come to that ( and we will one day) : Always Follow the RAs like your life depends on it , because it might.
