I wholeheartedly agree with Islander2. A couple of 'clarifications' and some other fluffy stuff but basically the same as before. If there was nothing fundamentally wrong with ATSOCAS, why go through the re-naming process? If one is to believe the party line about education, I presume that the names will change again in 10 years or so.
There was definitely a need for education and common standards of application but all this rubbish?
PS. What's the difference between VFR and IFR in uncontrolled airspace? Terrain safe and quadrantals. I believe you will find that both will continue to apply for DS.
