A319 CAPTAIN REPORTS DISTRACTION FROM FALSE FUEL TANK TEMPERATURE ECAM WARNING DURING TKOF ROLL.

Narrative

DURING THE INITIAL TKOF ROLL; WE RECEIVED AN ERRONEOUS EFIS ALERT FOR LOW FUEL TEMP IN THE #2 MAIN FUEL TANK. SINCE THE TANK TEMP SHOWED -55 DEG C (-67 DEG F) AND THE OUTSIDE AIR TEMP WAS ABOVE 80 DEGS F; IT WAS OBVIOUS THAT THE INDICATION WAS INCORRECT; SO WE CONTINUED THE TKOF. WITHIN 1 MIN AFTER LIFTOFF; THE TEMP INDICATION RETURNED TO NORMAL. THE A319 IS DESIGNED TO INHIBIT ALL BUT A NUMBER OF ALERTS DURING TKOF ONCE THE THRUST HAS BEEN SET. PRIOR TO THAT; ALERTS ARE DISPLAYED ON THE ECAM AND A CHIME IS SOUNDED. FOR TRUE MALFUNCTIONS; THE BENEFIT IS OBVIOUS. HOWEVER; ERRONEOUS INDICATIONS CAN CREATE TEMPORARY DISTRACTION AND CONFUSION DURING A CRITICAL PHASE OF FLT. FORTUNATELY FOR US; IT WAS DAYLIGHT VFR WITH NO TFC CONSIDERATIONS AND A LONG RWY AVAILABLE. HAD THE WX BEEN LOW IFR WITH A LOT OF TFC ON THE TXWY OR TFC ON SHORT FINAL; THE POTENTIAL EXISTED FOR AN UNNECESSARY ABORT OR GAR. COMPUTERIZED ACFT SYS CAN OCCASIONALLY GENERATE FAULTY INFO REQUIRING THE CREW TO ANALYZESITUATION CORRECTLY. DURING CERTAIN PHASES OF FLT; THIS CAN BE DIFFICULT AND POSE A REDUCTION IN THE MARGIN OF SAFETY IF THE INFO IS NOT CORRECTLY INTERPED.
