Are you saying that you do not add the recomended 200ft to the published OCH?
If that is true then you can use the absolute minima of 600ft provided that the IR OCH isn't more than that.
If however, you follow the CAA's advice and add 200ft to the published IR minima for the particular approach then why do you not follow your own criteria for another particular approach?
This would be similar to a pilot adding 200ft to say an NDB approach but not bothering for a VOR approach.
No - I'm not saying that at all and I'm well aware of what to add to the approach minima published - to the extent of editing my post to reflect that. Hope that clarifies matters - if not then you obviously have problems with the language which I can't be bothered to redress here.
