Narrative:
After takeoff, we were following the SID assigned in the clearance, until the departure control started to vector us to different altitudes and headings. Also, we were asked to maintain different airspds. In the climb, we were experiencing light to moderate turbulence. The altitude assigned at that particular moment was 11000 ft as I confirmed on the radio with the departure controller. I set 11000 ft on the altitude 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 right lap and put it in my left lap and opened it wider to make it more visible to him. Immediately after showing the captain the chart, I checked the flight instruments and noticed that he had flown through the assigned altitude (we were at 11800 ft) and I immediately exclaimed 'where are you going?' and before I was able to reach the controls with my hands and take evasive action and return to the assigned altitude, the captain immediately stopped the climb. While the PF was stopping the climb, I was scanning for air traffic. Right after, I noticed that the altitude warning system did not appear to be working properly.

Title: 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.
