Then you are clearly wrong. The fact that you see the approach lights
certainly does not indiciate that you have any visibility. As I
mentioned before you can see the approach lights through the fog but
not be able to see the ground around the lights. So your statement
that seeing the environment demonstrates the visibility, if you
include the apporach lights, cannot be correct.

I am not saying that at all.

Descent below the MDA, or continuation of the approach beyond DA,
requires 3 conditions:

1) Runway environment in sight
2) Normal rates of descent, etc...
3)Flight visibility as specified...

All 3 conditions must be met. Approach lights satisfy condition 1.


The letter of the law is the letter of the law, but the spirit behind it
is "don't crash"

1/8 mile is not enough to transition to visual manuevering by hand.

Period.
