TCAS protection volumes
Hi,
This thread is aimed particularly at pilots flying in Oceanic Control Areas. As an ATCO working in an OCA I'd like to clear some doubts regarding TCAS protection volumes. As you know, separation minima are way higher in oceanic areas than those applied where radar services are provided. Do the TCAS protection volumes also increase (lateral and longitudinally)? Are the TCAS settings changed when crossing from one area to another? Does this depend on the airlines' procedures?
I can't seem to find a clear answer to this on documents. Thanks for your help.
Cheers!
