Spotted it! Thanks!
It wasn't placed properly (at all) and I couldn't guess that it was an actual TR on our paper copy on board.
I was wondering why AI referred only to AP's in AP/FD required equipment section.
It's now crystal clear!
Funny enough, our A330 MEL does not permit for CAT IIIB without FD's (clearly written) while our A320 MEL has no provision for that dispatch case...
