I've been told that ICAO defines "established" as at least 1/2 scale CDI. The AIM is far more very vague, so the ICAO definition is obviously better to teach instrument students. Of course, the latest PTS permits in most cases no more than 3/4 scale for most tasks.
HOWEVER, I'm not able to find a decent reference for this. If anyone knows where this is actually published, please let me know! If this discussion is in a thread already, please enlighten me...
Thanks all!
