Narrative:

Captain loaded FMS, (his leg) quick align was down prior to loading position and route. After captain loaded, I check it, everything was correct. Did the checklist, and waited for final papers. Final weights and takeoff numbers arrived, wrong runways were listed (6 and 7) no numbers for runway 25 or 24. (ATIS: -8 scattered 15 overcast 1 1/2 RF 56 degrees 56 degrees 080 at 10 KTS 30.01. Next ATIS: -8 scattered 15 overcast 1 1/2 RF 56 degrees 56 degrees 090 at 8 KTS 29.99.) we requested numbers for runways 24 and 25, after about 15 min delay received new takeoff data authority/authorized for takeoff, flaps 15 degrees, runways 25 or 24. While waiting in line for takeoff on runway 25R, 2 B747 aircraft departed from runway 7L another holding short of runway 7L. 'Departure clearance -- lax angel 1 holtz trm transition maintain 2000 ft.' cleared for takeoff runway 25R maintain 3000 ft. Heading hold selected, 220 degrees in the MCP window, smo 160 degree enter on the fix page, provided a broken green line off the smo VOR 160 degree radial for our turn to heading 220 degrees. Climbing out gear up, 1000 ft VNAV, clean up flaps, waiting for the FMS 'intersection' to reach the broken green line to select heading select. It appeared the FMS 'intersection' was lagging behind the actual aircraft position. (We did write that up as a maintenance item going into atl). Prior to our FMS 'intersection' reaching the smo 160 degree radial, departure turn us to a heading off 180 degree maintain 13000 ft 250 KTS, later clear to direct peelee 17000 ft normal speed flight plan. 5 or 6 frequency changes later, ZAB gave us a phone number to call, la TRACON about a possible traffic conflict. After departure and remainder of flight to atl the FMS appeared to operate normal, and no further problems. Not sure if ground interference, map shift or what??, too late then to go to raw data. We changed aircraft in atl and continue on to ewr. Later heard another crew had problem with FMS to rdu, not sure to what extent. Captain talked to la TRACON and they said we were 3 mi past the smo 160 degree radial, and a conflict with an MD87. We did not receive any TCASII advisory?

Title: ARTCC STATES THAT ACFT DEPARTING FROM LAX HAD A TFC CONFLICT. DEPARTING TFC NEVER HAD ANY SIGN OF A CONFLICT AS THEY WERE IMC DURING DEP. THERE WERE NO TCASII ADVISORIES.

Narrative: CAPT LOADED FMS, (HIS LEG) QUICK ALIGN WAS DOWN PRIOR TO LOADING POS AND RTE. AFTER CAPT LOADED, I CHK IT, EVERYTHING WAS CORRECT. DID THE CHKLIST, AND WAITED FOR FINAL PAPERS. FINAL WTS AND TKOF NUMBERS ARRIVED, WRONG RWYS WERE LISTED (6 AND 7) NO NUMBERS FOR RWY 25 OR 24. (ATIS: -8 SCATTERED 15 OVCST 1 1/2 RF 56 DEGS 56 DEGS 080 AT 10 KTS 30.01. NEXT ATIS: -8 SCATTERED 15 OVCST 1 1/2 RF 56 DEGS 56 DEGS 090 AT 8 KTS 29.99.) WE REQUESTED NUMBERS FOR RWYS 24 AND 25, AFTER ABOUT 15 MIN DELAY RECEIVED NEW TKOF DATA AUTH FOR TKOF, FLAPS 15 DEGS, RWYS 25 OR 24. WHILE WAITING IN LINE FOR TKOF ON RWY 25R, 2 B747 ACFT DEPARTED FROM RWY 7L ANOTHER HOLDING SHORT OF RWY 7L. 'DEP CLRNC -- LAX ANGEL 1 HOLTZ TRM TRANSITION MAINTAIN 2000 FT.' CLRED FOR TKOF RWY 25R MAINTAIN 3000 FT. HDG HOLD SELECTED, 220 DEGS IN THE MCP WINDOW, SMO 160 DEG ENTER ON THE FIX PAGE, PROVIDED A BROKEN GREEN LINE OFF THE SMO VOR 160 DEG RADIAL FOR OUR TURN TO HDG 220 DEGS. CLBING OUT GEAR UP, 1000 FT VNAV, CLEAN UP FLAPS, WAITING FOR THE FMS 'INTXN' TO REACH THE BROKEN GREEN LINE TO SELECT HDG SELECT. IT APPEARED THE FMS 'INTXN' WAS LAGGING BEHIND THE ACTUAL ACFT POS. (WE DID WRITE THAT UP AS A MAINT ITEM GOING INTO ATL). PRIOR TO OUR FMS 'INTXN' REACHING THE SMO 160 DEG RADIAL, DEP TURN US TO A HDG OFF 180 DEG MAINTAIN 13000 FT 250 KTS, LATER CLR TO DIRECT PEELEE 17000 FT NORMAL SPD FLT PLAN. 5 OR 6 FREQ CHANGES LATER, ZAB GAVE US A PHONE NUMBER TO CALL, LA TRACON ABOUT A POSSIBLE TFC CONFLICT. AFTER DEP AND REMAINDER OF FLT TO ATL THE FMS APPEARED TO OPERATE NORMAL, AND NO FURTHER PROBS. NOT SURE IF GND INTERFERENCE, MAP SHIFT OR WHAT??, TOO LATE THEN TO GO TO RAW DATA. WE CHANGED ACFT IN ATL AND CONTINUE ON TO EWR. LATER HEARD ANOTHER CREW HAD PROB WITH FMS TO RDU, NOT SURE TO WHAT EXTENT. CAPT TALKED TO LA TRACON AND THEY SAID WE WERE 3 MI PAST THE SMO 160 DEG RADIAL, AND A CONFLICT WITH AN MD87. WE DID NOT RECEIVE ANY TCASII ADVISORY?
