Absolutely correct Bernd, the only problem I still see is the (until now ) refusal of the FAA to consider mandating the CP change and any new TCAS version for that matter.
Possibly the new US Administration will change some of the FAA top, but even with new people I have my doubts that the attitude will drastically change overnight.
Punkalouver , you've made your points already many times here , we noted them. Why don't you just follow your RAs as the book says and come back here when you have something new to say?
