Landing Into Fog

[Trixter36]

Hello Pilots,

Interesting approach and landing into Auckland, New Zealand.
Landing in fog using an instrument approach procedure called CAT III.

That's got to be about an RVR (Runway Visual Range) of 750-1000 feet!

Take a look at this NZAA 23L ILS/DME approach plate: http://www.aip.net.nz/pdf/NZAA_41.3.pdf

Notice how the section that defines "minimums" (very bottom of the approach plate) indicates the minimum RVR in which an aircraft can continue the CATII and CATIII approaches. With a CATII capable aircraft (basically has some extra redundant navigation equipment), RVR has to be at least 300 meters (which it appears is not the case in this situation), but if the aircraft is CATIII capable (has even more extra redundant navigation equipment), they can do this approach with less than a 300 meter RVR (down to 75m).

Side note: the rest of the approach plate indicates distances and altitudes in feet. Why are the RVR minimums listed in meters? Is RVR75 indicating you can fly the approach with RVR about as long a half-decent outfielder can throw a baseball (75 meters) or is it the distance from home plate to first base (a little more than 75 feet)? Granted, the latter seems kind of ridiculous, considering that's less than the length of your average A320 (123 feet)!
