Narrative:
Overweight landing mitigated by erratic fuel gauge, shorter than planned taxi and favorable en route conditions. ZFW at maximum, consequently minimum fuel and maximum fuel were the same value. Overweight landing inspection accomplished -- no damage found. A contributing factor is that air carrier X uses pounds for load manifest and flight plan. Aircraft fuel gauges and FMS in kilograms. Dripless fuel sticks calibrated in inches -- this leads to much possible confusion. Flcs generally overfuel aircraft to avoid possible conversion errors.
Original NASA ASRS Text
Title: FLC OF A LOCKHEED 1011 LANDED OVERWT AND HAD ACFT INSPECTED AS REQUIRED PRIOR TO NEXT FLT.
Narrative: OVERWT LNDG MITIGATED BY ERRATIC FUEL GAUGE, SHORTER THAN PLANNED TAXI AND FAVORABLE ENRTE CONDITIONS. ZFW AT MAX, CONSEQUENTLY MINIMUM FUEL AND MAX FUEL WERE THE SAME VALUE. OVERWT LNDG INSPECTION ACCOMPLISHED -- NO DAMAGE FOUND. A CONTRIBUTING FACTOR IS THAT ACR X USES LBS FOR LOAD MANIFEST AND FLT PLAN. ACFT FUEL GAUGES AND FMS IN KILOGRAMS. DRIPLESS FUEL STICKS CALIBRATED IN INCHES -- THIS LEADS TO MUCH POSSIBLE CONFUSION. FLCS GENERALLY OVERFUEL ACFT TO AVOID POSSIBLE CONVERSION ERRORS.
