Just as I advised Iceman earlier that indeed all 330 are not CAT D , I would caution against being dogmatic that all ARE CAT C . Airbus has a habit of doing different things for different operators and there are several higher landing weight versions ( 343, 342 ) ,engine & airframe combinations that may be certified CAT D .With AIrbus , you just never know . You can verify what you operate , Iceman says his are CAT D . I would leave it at that .
Regarding non normal configuration & circling minima , under PansOPS , as far as I know , there is no obligation to move up a category based on actual approach speed / configuration . The approach category criteria is based upon certified approach category ( Stall speed ratio in landing config at Max landing mass) . However maybe TERPS and your company apply different .
