Wunwing,
We can make circular arguments all day. There are 4 ICAO standards and Europe and now Australia are in effect saying you need to be Chapter 3 compliant and whatever the bypass ratio is they want to apply. No country has to adopt ICAO standards and only ICAO standards for anything. Australia for instance publishes its differences from ICAO.
The rights or wrongs of this is what you are arguing.
This is the end of it for me. No use going round in circles. This would seem to affect only one aircraft at the moment and it is doomed for the reasons I put in a previous post. Logic along your lines has nothing to do with it.
