MEL 34-48M in my book says 2 INS/0 REQ. Can't do CAT II or III. That's it.
REMARKS AND EXCEPTIONS
May be inoperative provided approach procedures do not require its use.
NOTE:
Must be operative for CAT II/III approaches
I see someone posted the same. My MEL has a "change bar" next to this item. I wonder if the update this difference.
