Narrative:

This was the second day of flying for a company new hire who had no previous medium large transport or part 121 experience. I was the check airman and he was the PF accomplishing his IOE from the right seat. We had been cleared the karlo 1 arrival with a crossing restriction of 12,000' and 280 KTS at plsnt intersection. This was programmed in the FMC and the aircraft was coupled to the autoplt and FMC, flying in LNAV and VNAV. We were cleared on a shortcut direct plsnt and complied using the VMC. After being handed off to approach control, the speed restriction was deleted, however, we made no adjustments as the flight was on schedule. Passing plsnt intersection approach called and asked for our altitude which was 15,100 and I responded and then realized we had failed to make the restriction. The controller then cleared us to 11,000 and nothing else was said. We had become distracted during the training and failed to notice the FMC was not descending fast enough to make the crossing restriction. When it was brought to our attention, the FMC had already begun navigating to the next waypoint, hence no information for plsnt including the restrictions we programmed were visible on the CDU any longer. Consequently I have no idea why the VNAV failed to comply with the restriction or if it was misprogrammed.

Title: MLG ON ARRIVAL TO PHX. ACFT BEING FLOWN BY FO IN TRAINING. FMC PROGRAMMED FOR INTXN CROSSINGS. ON AUTOPLT. ACFT FAILED TO MAKE ALT RESTRICTION AT PLSTN INTXN. FLT CREW HAD ALLOWED FMC TO PROCEED TO NEXT WAYPOINT AND DISREGARDED CROSSING RESTRICTION.

Narrative: THIS WAS THE SECOND DAY OF FLYING FOR A COMPANY NEW HIRE WHO HAD NO PREVIOUS MLG OR PART 121 EXPERIENCE. I WAS THE CHECK AIRMAN AND HE WAS THE PF ACCOMPLISHING HIS IOE FROM THE RIGHT SEAT. WE HAD BEEN CLRED THE KARLO 1 ARR WITH A XING RESTRICTION OF 12,000' AND 280 KTS AT PLSNT INTXN. THIS WAS PROGRAMMED IN THE FMC AND THE ACFT WAS COUPLED TO THE AUTOPLT AND FMC, FLYING IN LNAV AND VNAV. WE WERE CLRED ON A SHORTCUT DIRECT PLSNT AND COMPLIED USING THE VMC. AFTER BEING HANDED OFF TO APCH CTL, THE SPEED RESTRICTION WAS DELETED, HOWEVER, WE MADE NO ADJUSTMENTS AS THE FLT WAS ON SCHEDULE. PASSING PLSNT INTXN APCH CALLED AND ASKED FOR OUR ALT WHICH WAS 15,100 AND I RESPONDED AND THEN REALIZED WE HAD FAILED TO MAKE THE RESTRICTION. THE CTLR THEN CLRED US TO 11,000 AND NOTHING ELSE WAS SAID. WE HAD BECOME DISTRACTED DURING THE TRAINING AND FAILED TO NOTICE THE FMC WAS NOT DESCENDING FAST ENOUGH TO MAKE THE XING RESTRICTION. WHEN IT WAS BROUGHT TO OUR ATTN, THE FMC HAD ALREADY BEGUN NAVIGATING TO THE NEXT WAYPOINT, HENCE NO INFORMATION FOR PLSNT INCLUDING THE RESTRICTIONS WE PROGRAMMED WERE VISIBLE ON THE CDU ANY LONGER. CONSEQUENTLY I HAVE NO IDEA WHY THE VNAV FAILED TO COMPLY WITH THE RESTRICTION OR IF IT WAS MISPROGRAMMED.
