Narrative

THIS IS A CLASSIC CASE OF HOW TO HAVE AN ACCIDENT WITH THE GLASS COCKPIT. I WAS THE REGULAR PLT; BUT FLYING AS RELIEF. THE COPLT WAS FLYING; LAX TO LHR FLT ON JAN/SAT/98. THE CAPT WAS UNDER STRESS. HE JUST COMMITTED HIS CLOSE RELATIVE TO A MENTAL INSTITUTION. HE STATED HE THOUGHT SOMETHING WAS WRONG WITH HIS HEART. HE TOLD ME TO KEEP AN EYE ON THE COPLT BECAUSE ON PREVIOUS TRIPS HE WOULD LOSE HIS SIT AWARENESS. THERE WAS A LOT OF CONFUSION ON COCKPIT SETUP. TWO MECHS HAD TO CLR TWO STATUS MESSAGES. THE FUELER WAS HAVING TROUBLE BALANCING THE FUEL. THEN THE DATA MODE DEFAULTED TO THE #2 RADIO. BUT FINALLY WE GOT GOING. WE DEPARTED ON THE LOOP DEP OUT OF LAX. THE COPLT MISSED THE L TURN AT 2 MI AND HAD TO BE DIRECTED TO TURN BY THE CAPT. AT THIS POINT THE CAPT REALIZED THAT THE DEP WAS NOT INSTALLED. HE PUT IN LAX AND HIT (NAV) AND ASKED THE COPLT TO FLY THE SID WHILE HE TRIED TO FIGURE OUT WHAT WAS WRONG WITH THE COMPUTER. THE COPLT FLEW STRAIGHT TO THE VOR AND THEN KEPT GOING STRAIGHT. I TOLD HIM HE HAD TO TURN R. HE ASKED IF HE COULD PUT ON THE AUTOPLT; THE CAPT SAID NO; JUST FLY THE PLANE. HE TURNED BACK R AND THEN TURNED OUTBOUND. AT THIS POINT ZLA TOLD US TO CLB TO FL260 AND TFC AT 3 O'CLOCK POS. THE NEXT THING WE GOT WAS TCASII 'DSND NOW.' WE SAW THE OTHER ACFT PASS IN FRONT. THE COPLT DID NOT REACT TO THE TCASII RA AND HAD TO BE TOLD BY BOTH OF US TO DSND. IT APPEARED ZLA WAS NEVER AWARE OF THE CONFLICT. THE PROB WAS THAT THE CAPT INSTALLED LAX AS DEST INSTEAD OF LHR. AS A RESULT; THE PREVIOUS FLT'S INBOUND ARR WAS STILL SHOWING TO LAX. THIS IS WHAT THE COPLT THOUGHT WAS THE OUTBOUND COURSE. THIS PUT HIM S OF THE OUTBOUND RADIAL AND CAUSED THE TFC CONFLICT. WHY ZLA DID NOT CATCH IT IS BEYOND ME. LESSONS: 1) THE PLT WHO INSTALLS INFO INTO THE COMPUTER; MUST HAVE EACH PAGE CHKED BY THE OTHER PLT. 2) THE PF SHOULD ALWAYS BACK UP WITH RAW DATA. 3) DO NOT DO COMPUTER WORK THAT'S COMPLICATED BELOW 18000 FT. 4) IF YOU ARE STRESSED OUT AND NOT FEELING WELL; GO ON SICK LEAVE.
