I had an waiver to go to 150' on a cat 1 approach for fog seeding. I had to
take a
check ride in the 182 with the FAA. It was an easy ride, and on one
appraoch, he kept me under the hood thru rollout. I regularly took off under
W0X0F conditions, (indefinite, 0 ceiling obscured, 0 visibility in fog.) We
could generally burn it out to 300 and a mile after 1 hour. (We poured a 1
pound coofee can full of ground up dry ice out of a hole in the belly,
during a 150' pass down the active.)

I read a report about a local airport with this statement:

"With existing Instrument Landing System (ILS) technology, inclement
weather, such as fog, is not a material obstacle to commercial service
operations."

I was under the impression that the FAA says fog is 1/4 mile
visibility. Can anyone legally land in fog?

That raises another question: Who here has gotten the certification
for non-commercial Cat II? How difficult was the certification? Was it
worth the trouble? How difficult was it to maintain the currency? I've
thought it might be cool to be able to fly Cat II in a Cherokee, but I
doubt it's worth the trouble.
