Narrative:

On departure our level off altitude was 8000 ft. As we approached 8000, the PF attempted to reduce the rate of climb with the vertical speed knob right at altitude hold point. He inadvertently hit the IAS button. The aircraft climbed through 8000 and was stopped between 8300 and 8500 ft. The PF then returned the aircraft to 8000 ft. I feel that our company stresses automatic flight too much and neglects the basics of manual operation. The captain was new and was confused by the autoplt and did not revert to manual operation to stop the climb. I also believe that the company's altimeter procedures lead to this type of problem. Below 10000 we use QFE and the one altimeter with MSL is out of both pilots' scan. I was in the process of resetting my altimeter at the time of the altitude deviation.

Title: AN ACR MLG CREW OVERSHOT ITS ASSIGNED ALT ON INITIAL CLBOUT.

Narrative: ON DEP OUR LEVEL OFF ALT WAS 8000 FT. AS WE APCHED 8000, THE PF ATTEMPTED TO REDUCE THE RATE OF CLB WITH THE VERT SPD KNOB RIGHT AT ALT HOLD POINT. HE INADVERTENTLY HIT THE IAS BUTTON. THE ACFT CLBED THROUGH 8000 AND WAS STOPPED BTWN 8300 AND 8500 FT. THE PF THEN RETURNED THE ACFT TO 8000 FT. I FEEL THAT OUR COMPANY STRESSES AUTO FLT TOO MUCH AND NEGLECTS THE BASICS OF MANUAL OP. THE CAPT WAS NEW AND WAS CONFUSED BY THE AUTOPLT AND DID NOT REVERT TO MANUAL OP TO STOP THE CLB. I ALSO BELIEVE THAT THE COMPANY'S ALTIMETER PROCS LEAD TO THIS TYPE OF PROB. BELOW 10000 WE USE QFE AND THE ONE ALTIMETER WITH MSL IS OUT OF BOTH PLTS' SCAN. I WAS IN THE PROCESS OF RESETTING MY ALTIMETER AT THE TIME OF THE ALTDEV.
