Wiz,
The 200m is required so that, from the 50' DH, enough of the runway can be seen to provide lateral guidance (3 consecutive runway lights) as roll out guidance is not guaranteed with CatIIIA..
There's no reference to the aircraft whatsoever. Never mind, CAT III A ground facility does guaranty rollout guidance. CAT III A certified aircraft under EU OPS doesn't require rollout guidance, that's correct. Other than EU OPS CAT III A with NO DH rollout guidance is required for obvious reasons. RVR requirements are different as well. Just pointing out that EU OPS is different from ICAO and FAA.
