Inbound to airport ATIS was reporting conditions well above minimums. As we were being radar vectored for the ILS 36 at dca, approach control began reporting RVR's. Upon receiving intercept vector we were given an RVR touchdown of 1200, rollout first officer 3500 and then clrd for the approach. I questioned the captain, he was obviously thinking about the situation, but said nothing. We continued the approach. It was apparent that an aircraft was landing in front of us and another being turned on the approach behind us. We were handed off to tower who reported the same RVR's and clrd us to land. We broke out well above minimums with the airport well in sight. A thin fog bank was at the approach end of the runway, accounting for the low touchdown RVR, but prevailing visibility was at least 2 mi. We landed with no problems. Captain stated that dca recognized the nature of the local condition and no need to worry. Technically, we were wrong to land, but no intent of any regulation was violated. Something must be clarified to allow such activity.

Title: RVR REPORTED BELOW LNDG MINIMUMS BEFORE THE ACFT WAS ESTABLISHED ON THE FINAL APCH COURSE.
Narrative: INBND TO ARPT ATIS WAS REPORTING CONDITIONS WELL ABOVE MINIMUMS. AS WE WERE BEING RADAR VECTORED FOR THE ILS 36 AT DCA, APCH CTL BEGAN REPORTING RVR'S. UPON RECEIVING INTERCEPT VECTOR WE WERE GIVEN AN RVR TOUCHDOWN OF 1200, ROLLOUT FO 3500 AND THEN CLRD FOR THE APCH. I QUESTIONED THE CAPT, HE WAS OBVIOUSLY THINKING ABOUT THE SITUATION, BUT SAID NOTHING. WE CONTINUED THE APCH. IT WAS APPARENT THAT AN ACFT WAS LNDG IN FRONT OF US AND ANOTHER BEING TURNED ON THE APCH BEHIND US. WE WERE HANDED OFF TO TWR WHO RPTED THE SAME RVR'S AND CLRD US TO LAND. WE BROKE OUT WELL ABOVE MINIMUMS WITH THE ARPT WELL IN SIGHT. A THIN FOG BANK WAS AT THE APCH END OF THE RWY, ACCOUNTING FOR THE LOW TOUCHDOWN RVR, BUT PREVAILING VIS WAS AT LEAST 2 MI. WE LANDED WITH NO PROBS. CAPT STATED THAT DCA RECOGNIZED THE NATURE OF THE LCL CONDITION AND NO NEED TO WORRY. TECHNICALLY, WE WERE WRONG TO LAND, BUT NO INTENT OF ANY REG WAS VIOLATED. SOMETHING MUST BE CLARIFIED TO ALLOW SUCH ACTIVITY.
