You are shooting an ILS approach and the vis is being reported at 3/4SM BRFG and the RVR is 1800. Assume all the components are working and you need RVR of 1800 for the approach.

You begin the approach and you are now inside the marker and cleared to land. You are coming up and DH and can see the touchdown zone clearly and tower reports RVR has dropped to 600. /ubbthreads/images/graemlins/shocked.gif

What do you do? Go around or land? Can you legaly land?
 
Which RVR reporting system says it's at 600? Rollout? Because if you see the touchdown zone (91.whatever the reg is) then you can land.
 
Continue the approach.

Bands of fog can move in and out of the runway area, so the RVR can chang on a minute, by minute basis.

You have been cleared for the approach, and are inside the FAF, then you are leagel to fly the approach. If no runway in sight at DH, then missed approach and it's on to your alternate.
 
91.175 clearly states that FLIGHT VISIBILITY is what is needed to land.

If you can see the runway from the end of the rabbit you have at least 2400'

Land.
 
Land. It is legal. Once inside the FAF/FAP it does not matter. Also, approach standards depend on your flight rules, i.e. 121, 135, 91. If you are Part 91, you can start an approach with 0/0 reported.
