if I do fly there with my shiny Airbus, what minima do I put in the box?
Whatever the company tells you to, you won't get it from LIDO unless the company has used the CCI page (Company and Crew Information) or had them printed on the main plate which it seems they haven't.
Perhaps it would be more useful to ask your employer, they must an approval so the figures will be somewhere.
Who is the operator? If the figures aren't available for a particular runway they may not have approval to operate CAT3 on to it so I would be cautious.
