THE AVAILABILITY OF ONLY 1 CHART IN THE COCKPIT CONTRIBUTES TO AN ALT OVERSHOOT AND A TFC CONFLICT DURING A MUCH REVISED DEP FROM LAS; NV.

Narrative

AFTER TKOF; WE WERE FOLLOWING THE SID ASSIGNED IN THE CLRNC; UNTIL THE DEP CTL STARTED TO VECTOR US TO DIFFERENT ALTS AND HDGS. ALSO; WE WERE ASKED TO MAINTAIN DIFFERENT AIRSPDS. IN THE CLB; WE WERE EXPERIENCING LIGHT TO MODERATE TURB. THE ALT ASSIGNED AT THAT PARTICULAR MOMENT WAS 11000 FT AS I CONFIRMED ON THE RADIO WITH THE DEP CTLR. I SET 11000 FT ON THE ALT ALERTER AND I SAID '11000 FT;' AND AT 10000 FT; I CALLED 1000 FT TO GO. AT THAT MOMENT; THE PF ASKED ME; 'LET ME SEE THE CHART' AND SO I TOOK THE CHART FROM MY R LAP AND PUT IT IN MY L LAP AND OPENED IT WIDER TO MAKE IT MORE VISIBLE TO HIM. IMMEDIATELY AFTER SHOWING THE CAPT THE CHART; I CHKED THE FLT INSTS AND NOTICED THAT HE HAD FLOWN THROUGH THE ASSIGNED ALT (WE WERE AT 11800 FT) AND I IMMEDIATELY EXCLAIMED 'WHERE ARE YOU GOING?' AND BEFORE I WAS ABLE TO REACH THE CTLS WITH MY HANDS AND TAKE EVASIVE ACTION AND RETURN TO THE ASSIGNED ALT; THE CAPT IMMEDIATELY STOPPED THE CLB. WHILE THE PF WAS STOPPING THE CLB; I WAS SCANNING FOR AIR TFC. RIGHT AFTER; I NOTICED THAT THE ALT WARNING SYS DID NOT APPEAR TO BE WORKING PROPERLY.
