Narrative:
Finished chkout on large transport first officer 6/89. No position until 10/89. Flew simulator in 9/89 for 90-day landing currency. You could say the find points of working the FMC had escaped my memory. We were cruising at FL390 and received clearance to FL410. Captain loaded in MCP glareshield altitude--at which point I asked how he input the data for the climb, neither monitoring to confirm the climb to FL410. Several mins later center asked if we had climbed. 'No, still at 290.' the altitude had not been put in the FMC, and we were navigating with VNAV and LNAV. Both crew members low experience levels in type contributory to the altitude oversight. Factors affecting performance: 1) supervision management practice of putting 2 inexperienced crew members together, or 2) just not monitoring/keeping track of crews' levels of experience; and 3) after training crew member on advanced/automated cockpit, waiting an extended period before assignment to aircraft. Fly the aircraft.

Title: ACR LGT RECEIVED AMENDED CLRNC ALT ASSIGNMENT, BUT DID NOT CLIMB UNTIL REMINDED 5 MINUTES LATER WHEN QUESTIONED BY ARTCC.
Narrative: FINISHED CHKOUT ON LGT F/O 6/89. NO POS UNTIL 10/89. FLEW SIMULATOR IN 9/89 FOR 90-DAY LNDG CURRENCY. YOU COULD SAY THE FIND POINTS OF WORKING THE FMC HAD ESCAPED MY MEMORY. WE WERE CRUISING AT FL390 AND RECEIVED CLRNC TO FL410. CAPT LOADED IN MCP GLARESHIELD ALT--AT WHICH POINT I ASKED HOW HE INPUT THE DATA FOR THE CLB, NEITHER MONITORING TO CONFIRM THE CLB TO FL410. SEVERAL MINS LATER CENTER ASKED IF WE HAD CLBED. 'NO, STILL AT 290.' THE ALT HAD NOT BEEN PUT IN THE FMC, AND WE WERE NAVIGATING WITH VNAV AND LNAV. BOTH CREW MEMBERS LOW EXPERIENCE LEVELS IN TYPE CONTRIBUTORY TO THE ALT OVERSIGHT. FACTORS AFFECTING PERFORMANCE: 1) SUPERVISION MGMNT PRACTICE OF PUTTING 2 INEXPERIENCED CREW MEMBERS TOGETHER, OR 2) JUST NOT MONITORING/KEEPING TRACK OF CREWS' LEVELS OF EXPERIENCE; AND 3) AFTER TRNING CREW MEMBER ON ADVANCED/AUTOMATED COCKPIT, WAITING AN EXTENDED PERIOD BEFORE ASSIGNMENT TO ACFT. FLY THE ACFT.
