Narrative:

Climb out, assigned altitude FL230. As we passed FL210 (as I recall) we encountered moderate turbulence. Since we had just landed and had not experienced it then, I thought it might just be a small area and decided to slow to rough airspeed and at the same time climb through it. I did so by pulling back on the yoke. A phenomenal rate of climb resulted (it was a lightly loaded B757). At FL225 I saw the rate of climb was very high and pulled the throttles all the way to idle and eased over on the control column. I should have moved the control column more aggressively, but with the throttles off, I didn't think it would be a problem. We just rocketed through FL230. I shoved the nose forward and finally stopped the climb at FL235, and descended immediately to FL230. No comment was received from center. Contributing factors: my scan was slower due to an oncoming cold. I did get off the trip the next day due to that. As soon as we encountered the turbulence, the first officer notified the controller and of course was given a frequency change. His head was down, changing frequencys, just at the moment this all happened. Also my thoughts were diverted for a moment to thinking of the flight attendants, who I knew were up. In retrospect, having been aware that the oncoming cold was affecting me, I should have used the autoplt right away. In the early stages of that illness I don't feel sick enough to not take a trip, just a little, well -- blah. It does take the edge off one's performance.

Title: CAPT OF A B757 OVERSHOT CLB ALT WHEN HE TRIED TO SLOW ACFT IN THE CLB DUE TO TURB, BY ONLY PITCHING UP THE ACFT NOSE. HE IMMEDIATELY THROTTLED BACK AND PITCHED OVER TO RETURN TO ASSIGNED ALT.

Narrative: CLB OUT, ASSIGNED ALT FL230. AS WE PASSED FL210 (AS I RECALL) WE ENCOUNTERED MODERATE TURB. SINCE WE HAD JUST LANDED AND HAD NOT EXPERIENCED IT THEN, I THOUGHT IT MIGHT JUST BE A SMALL AREA AND DECIDED TO SLOW TO ROUGH AIRSPD AND AT THE SAME TIME CLB THROUGH IT. I DID SO BY PULLING BACK ON THE YOKE. A PHENOMENAL RATE OF CLB RESULTED (IT WAS A LIGHTLY LOADED B757). AT FL225 I SAW THE RATE OF CLB WAS VERY HIGH AND PULLED THE THROTTLES ALL THE WAY TO IDLE AND EASED OVER ON THE CTL COLUMN. I SHOULD HAVE MOVED THE CTL COLUMN MORE AGGRESSIVELY, BUT WITH THE THROTTLES OFF, I DIDN'T THINK IT WOULD BE A PROB. WE JUST ROCKETED THROUGH FL230. I SHOVED THE NOSE FORWARD AND FINALLY STOPPED THE CLB AT FL235, AND DSNDED IMMEDIATELY TO FL230. NO COMMENT WAS RECEIVED FROM CTR. CONTRIBUTING FACTORS: MY SCAN WAS SLOWER DUE TO AN ONCOMING COLD. I DID GET OFF THE TRIP THE NEXT DAY DUE TO THAT. AS SOON AS WE ENCOUNTERED THE TURB, THE FO NOTIFIED THE CTLR AND OF COURSE WAS GIVEN A FREQ CHANGE. HIS HEAD WAS DOWN, CHANGING FREQS, JUST AT THE MOMENT THIS ALL HAPPENED. ALSO MY THOUGHTS WERE DIVERTED FOR A MOMENT TO THINKING OF THE FLT ATTENDANTS, WHO I KNEW WERE UP. IN RETROSPECT, HAVING BEEN AWARE THAT THE ONCOMING COLD WAS AFFECTING ME, I SHOULD HAVE USED THE AUTOPLT RIGHT AWAY. IN THE EARLY STAGES OF THAT ILLNESS I DON'T FEEL SICK ENOUGH TO NOT TAKE A TRIP, JUST A LITTLE, WELL -- BLAH. IT DOES TAKE THE EDGE OFF ONE'S PERFORMANCE.
