AN ACR PILOT REPORTS THAT CAT III LOW MINIMUM WX FOR APCH AND LNDG IS NOT AVAILABLE VIA ACARS AT CERTAIN LOW MINIMUM CAPABLE ARPTS.

Narrative

WEATHER IN ZZZ WAS 1/4 MILE FZFG; WINDS CALM; TEMP -16/-16. ATTEMPTED TO PULL UP ACARS LANDING WEIGHT DATA FOR RUNWAY 32R LOW MINIMUMS; FLAPS 40; FOR A CAT III APPROACH AND LANDING. ACARS CAME BACK SAYING LM (LOW MINIMUM) DATA NOT AVAILABLE FOR 32R. I ACARSED DISPATCH FOR THE DATA. HIS RESPONSE WAS; 'AFTER FURTHER REVIEW I SEE THAT THE SYSTEM DOES NOT HAVE LO MIN DATA STORED FOR RWY 32R/14L. I'LL HAVE TO DERIVE DATA FROM THE FLT MANUAL.' I WAS ABLE TO GET THE INFORMATION OUT OF MY FLIGHT MANUAL. THE ISSUE I HAVE IS THE ACR NOT HAVING THIS DATA AVAILABLE IN ACARS.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT NOT HAVING THE DATA AVAILABLE IN THE USUAL ELECTRONIC FORM ADDS A BIT OF COMPLEXITY TO THE NORMAL OPERATION. WHEN THE WX IS DOWN THE CREW CAN USUALLY PLAN ON AN ACARS REQUEST FOR THE LANDING DATA AND A QUICK RESPONSE. WHEN THE DATA IS NOT AVAILABLE BUT IT IS EXPECTED TO BE AVAILABLE; THE CREW HAS TO ADD THE ADDITIONAL STEP OF MANUALLY LOOKING UP THE DATA IN A MANUAL NOT NORMALLY ACCESSED. THIS ADDITIONAL STEP DISRUPTS THE PRE-DESCENT BRIEFING.
