How does that "not compromise safety"?
Denti - sorry but I am not convinced. In any airprox, there are many ways of solving the problem - I climb, or you climb, or I descend, or you descend, or whatever. In many encounters, the TCAS coordination means that quite mild changes - or even "no change" - can be the solution. In some of the encounters however, a guaranteed solution may only be possible with a coordinated response. Since turning off your TCAS removes those from the possible solution set, then surely you have compromised the safety net?
