Narrative:

On climb out/takeoff denver tower changed altitude from 10000 ft to 7000 ft. When aircraft changed to altitude capture mode throttle went to idle. Nose still pitched up for climb. Captain commanded speed select change. When I looked down again we were passing 7100 ft. I called altitude, captain corrected, just as we hit some of the reported turbulence in the denver area. I think this shows the problems with short/low level, leveloffs after takeoff when aircraft are still in climb mode, power, flaps/slats, etc.

Title: A B757 CREW, ON CLBOUT FROM DEN, OVERSHOT THEIR ASSIGNED ALT.

Narrative: ON CLBOUT/TKOF DENVER TWR CHANGED ALT FROM 10000 FT TO 7000 FT. WHEN ACFT CHANGED TO ALT CAPTURE MODE THROTTLE WENT TO IDLE. NOSE STILL PITCHED UP FOR CLB. CAPT COMMANDED SPD SELECT CHANGE. WHEN I LOOKED DOWN AGAIN WE WERE PASSING 7100 FT. I CALLED ALT, CAPT CORRECTED, JUST AS WE HIT SOME OF THE RPTED TURB IN THE DENVER AREA. I THINK THIS SHOWS THE PROBS WITH SHORT/LOW LEVEL, LEVELOFFS AFTER TKOF WHEN ACFT ARE STILL IN CLB MODE, PWR, FLAPS/SLATS, ETC.
