Genuine doubt for ATC experts: Which is the spacing between the RWY center line lights before a displaced threshold on a CatIII aproved RWY? The FAA standards seems to give a possible selection between 30mts for approach lights and 15mts for take off, is this correct? Any supporting documents for this issue? Thanks!

For CATIII operations and take-off in RVR below 400m spacing should be 15m and no centerline lights before runway threshold lights.

ICAO allows white approach light centreline barrettes at 30m spacing to be used pre-landing threshold for Cat III take-offs instead of 15m spaced runway centreline lights. Ref Annex 14, Chapter 5, page 55.
