I've always wondered what the real differences were and indeed what the point was of many seemingly identical approach plates for the same runway.
Granted, the minima are different but many operators publish these seperately and they are subject to revision due NOTAMs, unserviceabilities, etc. anyway.
What is going to help you fly a better approach when using a Cat III chart instead of just one with the ILS on it? (Of whatever category) Am I missing something? A LVP taxi chart with the appropriate holding points is useful but that's on another page...
