ACR DEPARTS WITHOUT ALTERNATE FUEL REQUIRED FOR FLT.

Narrative

THIS WAS THE 4TH DAY OF A LONG TRIP. 15 SEGMENTS HAD BEEN FLOWN PRIOR TO THE PROBLEM AT ROA. FLT WAS DISPATCHED FROM IAD-ROA-ORD. DISPATCH SHOWED 3600 LBS BURN IAD-ROA. 11000 LBS MIN FUEL AND 16000 LBS RECOMENDED. 16000 LBS FUEL ON BOARD AT IAD. ON FLT TO ROA WX WAS NEAR MIN FOR ILS APCH; WE SHOT THAT APCH AND MISSED AS WX HAD GONE DOWN BELOW MIN. WE THEN WENT OUT TO SHOT THE LDA 6 APCH WHICH HAS LOWER MIN. SUCCESSFUL THIS TIME HOWEVER WE USED THE EXTRA FUEL AND TIME TO FLY THE APCH. THE RELEASE ROA- ORD SHOWED 9000 BURN AND 12000 MIN WE HAD ACFT FUEL BROUGHT UP TO 12000 LBS. FLT DEPARTED AND CLBED TO CRUISE AT 28000 FT. AFTER LEVELING OFF AT ALT AND BEING VECTORED FOR ENTRAIL SPACING TO ORD I NOTICED THE FUEL REMAINING AND THOUGHT THAT WAS TOO LOW FOR THE TIME AND DISTANCE PLUS RESERVE NEEDED TO COMPLETE THE FLT. ON RECOMPUTING THE FUEL I FOUND THAT AN ERROR HAD BEEN MADE IN THAT WE DID NOT HAVE THE 1800 LBS FOR OUR ALTERNATE AT MKE. WE WERE NOT IN A MIN FUEL SITUATION AT THIS TIME HOWEVER WE DID NOT HAVE ENOUGH TO FLY TO ORD MISS AND FLY TO OUR ALTERNATE AT MKE. WX AT ORD WAS 1600 OVCST AND 6F. RUNWAYS 27 L AND R AND 22 R WERE IN USE AND NO DELAY WERE EXPECTED. I DECIDED TO CONTINUE TO ORD. WE LANDED AT ORD WITH 4000 LBS OF FUEL REMAINING. 3000 LBS WOULD BE MIN FUEL. TWO DISPATCHERS AND TWO PLTS READ AND CONFIRMED THE FUEL AMOUNT AND NONE OF US CAUGHT THE ERROR OF NOT INCLUDING THE ALTERNATE FUEL THAT WAS REQUIRED FOR THIS FLT. NEXT TIME ADD ALL THE NUMBERS!
