It's a while since I took a really close look at all this and most of the requirements have already been listed.
However, another element is runway lighting. For example, every other centreline light has to be on an alternative circuit so that, in the event of a failure, you only lose half the available lights. A further requiremnt is that power must be restored to the failed component within (I think) 15 seconds or so - makes sense really?
One presumes that the authorities at JER have looked at the feasability of CAT 2/3 there but if by any chance they haven't they ought to given the wx record!
