Narrative:
During approach to runway 36L at dfw an extremely rapidly deteriorating WX conditions (fog bank) caused approach control and tower to bombard our cockpit crew with so much WX information and inquiries about the WX that it became difficult to perform the cockpit duties (i.e., checklists confign changes, etc) associated with this type of approach. The crew believes, but cannot be sure, that we were on the final approach phase of the published CAT I approach when the WX went below minimums for the approach. This confusion is a direct result of the almost constant communications we were required to respond to during the approach. We were asked 3 times if we had the ATIS (it changed 3 times during the approach)! We were given RVR information perhaps as many as 5 times after we were cleared for the approach. The communications situation became so intense as to become a distraction. In the interest of safety, approach control and tower should limit their communications to those required and then they should be given in a timely fashion well before the final approach phase.

Title: CAPT AND FO REPORTING TOO MUCH RADIO COM ON APCH TO DFW IN DETERIORATING WX.
Narrative: DURING APCH TO RWY 36L AT DFW AN EXTREMELY RAPIDLY DETERIORATING WX CONDITIONS (FOG BANK) CAUSED APCH CTL AND TWR TO BOMBARD OUR COCKPIT CREW WITH SO MUCH WX INFO AND INQUIRIES ABOUT THE WX THAT IT BECAME DIFFICULT TO PERFORM THE COCKPIT DUTIES (I.E., CHKLISTS CONFIGN CHANGES, ETC) ASSOCIATED WITH THIS TYPE OF APCH. THE CREW BELIEVES, BUT CANNOT BE SURE, THAT WE WERE ON THE FINAL APCH PHASE OF THE PUBLISHED CAT I APCH WHEN THE WX WENT BELOW MINIMUMS FOR THE APCH. THIS CONFUSION IS A DIRECT RESULT OF THE ALMOST CONSTANT COMS WE WERE REQUIRED TO RESPOND TO DURING THE APCH. WE WERE ASKED 3 TIMES IF WE HAD THE ATIS (IT CHANGED 3 TIMES DURING THE APCH)! WE WERE GIVEN RVR INFO PERHAPS AS MANY AS 5 TIMES AFTER WE WERE CLRED FOR THE APCH. THE COMS SITUATION BECAME SO INTENSE AS TO BECOME A DISTR. IN THE INTEREST OF SAFETY, APCH CTL AND TWR SHOULD LIMIT THEIR COMS TO THOSE REQUIRED AND THEN THEY SHOULD BE GIVEN IN A TIMELY FASHION WELL BEFORE THE FINAL APCH PHASE.
