I take it you are talking about Überlingen.
No dispute with Uberlingen, I share your views. In fact I am talking about Conhongas - pilots's decision not to implement available procedures.
ICAO, and Eurocontrol advisory documents, and they were all different.
So it was and the industry have learned eversince. I only attempt to show that another step was made and is a worldwide standard.
Well, this is legally just not right. The owner of the airspace in which you are flying defines the procedures. That's the document. And it changes every time you cross national boundaries. It is wishful thinking to imagine that all the countries in the world now agree on and have implemented in their air traffic regulations *exactly one* TCAS procedure, don't you think?
Could not agree more. I am ready to learn about airspaces/countries which decided not to adopt latest PANS-ATM chages, be it via web hearsay (and check with official sources if it is so). Until then, it is my responsibility as a pilot is to follow published procedures invented by people far more clever than me.
Groucho: My company would not advise me about recent changes in Doc 4444. They did show me €control ACAS bulletin, however. My SOPs which I must and will follow do not prescribe TCAS phraseologies, but they require me to adopt ICAO standards unless stated otherwise. There is a new standard in place, and I only attempt to bring it into the view of fellow pilots who may find themselves in the same position as I am.
At last, I am afraid
that the "new" procedure have been in place for 2 months and it is our responsibility to act accordingly.
