Narrative:

We were on final approach to runway 24R lax following a B747 for runway 24L. We were flight planned to land with 5200 pounds; but were actually landing with 4800 pounds. At 100 ft; the aircraft rocked left by 20 degrees and the PF (captain) initiated a missed approach. The missed went normal and we were instructed to fly a 250 degree heading to 5000 ft. The captain had me fly after the after takeoff checklist so that he could let the people know why we went around. Tower asked why we went around and we relayed that information. Then; departure was vectoring us behind a B767 and was cleared direct smo; 070 degree heading after smo; 170 KTS. I looked at the mcdu and it showed us landing with 3500 pounds now. The captain came back and then resumed the PF duties. We both felt that we needed to declare 'minimum fuel' and did so. We were still following the B767. After crossing smo; the left fuel tank 'low pressure ECAM' came on. I completed the ECAM's and the captain flew the airplane. The mcdu now had us landing with 2800 pounds. We were told to follow the B767 that we had in sight on our base leg. A saab was to pass behind us for runway 24L. We turned final and at 2500 ft AGL; we went tank-top-engine. Then; we got a descending RA from the saab. We descended to 1500 ft AGL. At this point we were configured gear down; flaps 3 degrees. We got back onto the GS and went flaps full. Both the captain and I agreed that if another go around was necessary that we would immediately declare an emergency and execute a r-hand visual pattern at 1500 ft AGL. At 1000 ft; we got another left fuel 'low pressure ECAM' and our fuel gauges showed a 1/2 rectangle indicating that the sensors were getting unreliable readings. We then got the 'land as soon as possible ECAM.' the PF descended towards the end of the runway and landed within the first 1/3 of the touchdown zone. After exiting the runway; we had indicating 2500 pounds of fuel and ended at the gate with 2300 pounds of fuel on board. The flight ended uneventfully; but my opinion of fleet planned landing fuel needs to be greater than 5200 pounds at highly congested airports regardless of WX. I also feel that the captain did an exemplary job with all of the conditions that we were encountering and that we worked well as a team throughout the whole event.

Title: THE CREW OF AN A320 ENCOUNTERED WAKE TURB FROM A B747 LNDG ON A PARALLEL RWY AT LAX AND WENT AROUND FROM 100 FT AGL. ACFT USED MORE FUEL ENRTE THAN PLANNED. ACFT LANDED WITH 2500 LBS OF FUEL.

Narrative: WE WERE ON FINAL APCH TO RWY 24R LAX FOLLOWING A B747 FOR RWY 24L. WE WERE FLT PLANNED TO LAND WITH 5200 LBS; BUT WERE ACTUALLY LNDG WITH 4800 LBS. AT 100 FT; THE ACFT ROCKED L BY 20 DEGS AND THE PF (CAPT) INITIATED A MISSED APCH. THE MISSED WENT NORMAL AND WE WERE INSTRUCTED TO FLY A 250 DEG HDG TO 5000 FT. THE CAPT HAD ME FLY AFTER THE AFTER TKOF CHKLIST SO THAT HE COULD LET THE PEOPLE KNOW WHY WE WENT AROUND. TWR ASKED WHY WE WENT AROUND AND WE RELAYED THAT INFO. THEN; DEP WAS VECTORING US BEHIND A B767 AND WAS CLRED DIRECT SMO; 070 DEG HDG AFTER SMO; 170 KTS. I LOOKED AT THE MCDU AND IT SHOWED US LNDG WITH 3500 LBS NOW. THE CAPT CAME BACK AND THEN RESUMED THE PF DUTIES. WE BOTH FELT THAT WE NEEDED TO DECLARE 'MINIMUM FUEL' AND DID SO. WE WERE STILL FOLLOWING THE B767. AFTER XING SMO; THE L FUEL TANK 'LOW PRESSURE ECAM' CAME ON. I COMPLETED THE ECAM'S AND THE CAPT FLEW THE AIRPLANE. THE MCDU NOW HAD US LNDG WITH 2800 LBS. WE WERE TOLD TO FOLLOW THE B767 THAT WE HAD IN SIGHT ON OUR BASE LEG. A SAAB WAS TO PASS BEHIND US FOR RWY 24L. WE TURNED FINAL AND AT 2500 FT AGL; WE WENT TANK-TOP-ENG. THEN; WE GOT A DSNDING RA FROM THE SAAB. WE DSNDED TO 1500 FT AGL. AT THIS POINT WE WERE CONFIGURED GEAR DOWN; FLAPS 3 DEGS. WE GOT BACK ONTO THE GS AND WENT FLAPS FULL. BOTH THE CAPT AND I AGREED THAT IF ANOTHER GAR WAS NECESSARY THAT WE WOULD IMMEDIATELY DECLARE AN EMER AND EXECUTE A R-HAND VISUAL PATTERN AT 1500 FT AGL. AT 1000 FT; WE GOT ANOTHER L FUEL 'LOW PRESSURE ECAM' AND OUR FUEL GAUGES SHOWED A 1/2 RECTANGLE INDICATING THAT THE SENSORS WERE GETTING UNRELIABLE READINGS. WE THEN GOT THE 'LAND ASAP ECAM.' THE PF DSNDED TOWARDS THE END OF THE RWY AND LANDED WITHIN THE FIRST 1/3 OF THE TOUCHDOWN ZONE. AFTER EXITING THE RWY; WE HAD INDICATING 2500 LBS OF FUEL AND ENDED AT THE GATE WITH 2300 LBS OF FUEL ON BOARD. THE FLT ENDED UNEVENTFULLY; BUT MY OPINION OF FLEET PLANNED LNDG FUEL NEEDS TO BE GREATER THAN 5200 LBS AT HIGHLY CONGESTED ARPTS REGARDLESS OF WX. I ALSO FEEL THAT THE CAPT DID AN EXEMPLARY JOB WITH ALL OF THE CONDITIONS THAT WE WERE ENCOUNTERING AND THAT WE WORKED WELL AS A TEAM THROUGHOUT THE WHOLE EVENT.
