You're nto going to be able to do that safely with 1/8 from 200' or
thereabouts.
1/8 mile is pretty ****ing small! That's Cat 3a minima.

I can't

think of any reason why this would not be. A typical GA plane may
be
stopped on the runway before a 747 touches down. I think vis
requirements, in general, for GA planes are a bit bogus, at least
with
regard to precision approaches.

Hand flown, you would have a lot of airplanes crashed into the
approach
lights.
An excepetional pilot would be able to do it most of the time,
though.
most of the time.

And I've done a LOT of instruments in singles and light twins. 1/4 is
reasonablem but 1/8. no.

Maybe this is different to me because I live in a fog valley. Today I
shoot 6 approaches. Weather was reported as 001OVC and 1/8SM. This is
pretty common weather here. I easily could have landed from any of the
approaches. Flying over the rabbit I clearly could see far enough of
the runway to land. Now, if a car pulled in front of me that would be
a different story but I don't think the FAA can protect against that
anyway.

Well, they're required to protect you against that in those sorts of
visses.

So, to me landing 1/8SM 001OVC is not unreasonably hard but I could
see it could be a handful going 150 knots in a 747.

Nope, it;s pretty much just the same. Even easier in some ways ( even
hand flown) The flight director, the multi crew co-ordination.
Don;'t get me wrong, I've done it and I know it can be done, but if you
were at 200' and could see that much the actual WX was better than
reported anyway.

At 200 feet all I can see is some light through the fog so I go down
to 100 above TDZE. At 100 feet I can see the chevrons or maybe the
runway numbers. If vis is 1/8 and I can see the runway numbers, its
hard to understand why the FAA prohibits landing.
