290kts,
He has to be referring to Cat III by definition. By basic FAR/AIM definition, a Cat II can't go lower than 1200 RVR, although we know from OPS Specs that it can go down to 1000RVR with autoland. To get a number as low as 700, they had to be doing a CAT III, they just had to make the decision on whether or not the airplane was going to land where it's supposed to at a higher altitude than we do probably because they were hand flying it.

Check the CRAR for the US and CAT IIIA. Page C-30
Now, you could also fly a CAT IIIB to an autoland and disconnect when the nosewheel touches down (contaminated rwy). Not sure if they are going to call that a 600 or a 700 RVR approach.
The FOM is going to change and you will see the 700 come back.

Understood MX727, I didn't even bother breaking down the individual CAT III parts, because I responding to a post that said a 700RVR approach could be a CAT II which it never could be without using Big Boy authority.
