Narrative:
During cruise flight, it was discovered that a 400 pound fuel imbal existed. A fuel xfeed was initiated. I usually turn the yellow light from radar altimeter on as a reminder of the xfeed procedure. This did not work. Subsequently, the xfeed went unchked until a 1500 pounds imbal existed. The xfeed was reinitiated and an imbal of 1000 pounds existed at landing (within the aircraft limitations). Inattn by both crew members and the lack of an established visual reminder led to this xfeed imbal.
Original NASA ASRS Text
Title: FLC FAILED TO MONITOR FUEL TRANSFER AFTER THE FUEL STORAGE BECAME IMBALED RESULTED IN IMBAL CORRECTIVE ACTION UP TO THE 1000 LBS ACCEPTABLE LNDG IMBAL.
Narrative: DURING CRUISE FLT, IT WAS DISCOVERED THAT A 400 LB FUEL IMBAL EXISTED. A FUEL XFEED WAS INITIATED. I USUALLY TURN THE YELLOW LIGHT FROM RADAR ALTIMETER ON AS A REMINDER OF THE XFEED PROC. THIS DID NOT WORK. SUBSEQUENTLY, THE XFEED WENT UNCHKED UNTIL A 1500 LBS IMBAL EXISTED. THE XFEED WAS REINITIATED AND AN IMBAL OF 1000 LBS EXISTED AT LNDG (WITHIN THE ACFT LIMITATIONS). INATTN BY BOTH CREW MEMBERS AND THE LACK OF AN ESTABLISHED VISUAL REMINDER LED TO THIS XFEED IMBAL.
