Lateral fuel imbal later determined to be a fuel required deviation and fuel remaining less than dispatch release required. Flight continuation with low fuel priority handling request resulted from flight crew response to event.

Narrative:
During takeoff rotation, captain experienced lateral control difficulties. Using fuel tanks (which had been checked and balanced prior to takeoff) now indicated 3000 pound split. After additional gauge testing, wing fuel tanks indicated 14000 pound split. Based on the captain's control inputs, the 14000 pound split was assumed to be accurate and fuel was transferred to alleviate the imbal. Due to shortage of fuel from what had been indicated at dispatch, priority handling was requested by the captain to make destination with required fuel reserves and to avoid an unscheduled fuel stop. Could be plane specific or fleetwide widebody transport indicating glitch.

Title: LATERAL FUEL IMBAL LATER DETERMINED TO BE A FUEL REQUIRED DEV AND FUEL REMAINING LESS THAN DISPATCH RELEASE REQUIRED. FLT CONTINUATION WITH LOW FUEL PRIORITY HANDLING REQUEST RESULTED FROM FLC RESPONSE TO EVENT.
Narrative: DURING TKOF ROTATION, CAPT EXPERIENCED LATERAL CTL DIFFICULTIES. USING FUEL TANKS (WHICH HAD BEEN CHKED AND BALANCED PRIOR TO TKOF) NOW INDICATED 3000 LB SPLIT. AFTER ADDITIONAL GAUGE TESTING, WING FUEL TANKS INDICATED 14000 LB SPLIT. BASED ON THE CAPT'S CTL INPUTS, THE 14000 LB SPLIT WAS ASSUMED TO BE ACCURATE AND FUEL WAS TRANSFERRED TO ALLEVIATE THE IMBAL. DUE TO SHORTAGE OF FUEL FROM WHAT HAD BEEN INDICATED AT DISPATCH, PRIORITY HANDLING WAS REQUESTED BY THE CAPT TO MAKE DEST WITH REQUIRED FUEL RESERVES AND TO AVOID AN UNSCHEDULED FUEL STOP. COULD BE PLANE SPECIFIC OR FLEETWIDE WDB INDICATING GLITCH.
