Approach category lesson

[riteortbit]

Thanks for the replys. I think I've spoted the source of my confusion. Please correct me if I'm wrong here.

1. The aircraft comes from the manufacturer certified to a specific approach category
2. the operator may have the aircraft recategorised with the approval of the State
3. The pilot may fly a different approach category profile on the day but still operate to the minima determined by 1 or 2 above
