FLC MISUNDERSTANDING OF FUEL SYS AND PROCS FOR FERRY FUEL.

Narrative

ENRTE TO ELP I DETERMINED THAT CTR TANK FUEL WAS NOT FEEDING THE ENGS; AS I HAD EXPECTED. MAIN FUEL TANK FEED WAS NORMAL AND SUFFICIENT ENOUGH TO COMPLETE OUR FLT; WITH REQUIRED FUEL RESERVES. AFTER CONSULTING OUR ACFT MANUAL AND DISPATCH VIA COMMERCIAL RADIO; WE CONTINUED TO ELP AND LANDED WITHOUT INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ACFT WAS FUELED FOR A THROUGH FLT AND WAS FERRYING EXTRA FUEL FOR THAT PURPOSE. WHEN RPTR NOTICED THE CTR TANK FUEL WAS NOT FEEDING THE ENGS; HE BECAME CONCERNED ABOUT THE EFFECT THAT WOULD HAVE ON THE CTR GRAVITY FOR LNDG. BY THE TIME RPTR CAPT DISCUSSED THE SIT WITH THE FO AND CONTACTED THEIR COMPANY DISPATCH; THEY WERE CLOSE TO THEIR DEST ARPT; HAD ADEQUATE FUEL; SO DSNDED AND LANDED UNEVENTFULLY. A REVIEW WITH HIS CHIEF PLT REVEALED THAT THERE WAS AN ABNORMAL PROC IN THEIR ACFT OPS MANUAL THAT SPECIFICALLY ADDRESSED THEIR SIT. RPTR SAYS HE WAS EMBARRASSED; BUT LEARNED A LOT. APPARENTLY THE FO WAS NOT ANY MORE AWARE OF THE PROPER PROC THAN THE CAPT.
