Narrative:
Just prior to rotation on takeoff, noticed #2 engine egt exceeding redline. Reduced thrust on that engine. After rotation, noticed #3 engine egt exceeding redline. Reduced thrust on that engine. On climb out, viewed snapshot on electronic engine indicating system (eids) and noted exceedences and duration. Advised dispatch and maintenance control of readings and were advised that no critical exceedences occurred, and that we were ok to continue to sea. Recorded exceedences and duration in aircraft maintenance logbook. Our company SOP is for the PF to set takeoff thrust by 80 KTS and for the PNF, to verify that the correct thrust is set by 80 KTS. I was flying, and after I initially set takeoff thrust, I took my hand temporarily off the throttles, and the first officer readjusted the power to a more exact setting. Prior to rotation, I glanced down at the power settings and called out the overtemp. The first officer felt that he had accurately adjusted the power, and that the EPR's bloomed to a slightly higher setting afterwards. My attention was focused more outside the aircraft, as we had a crosswind on takeoff. The first officer also commented that he felt that the new eids is harder to read, as the scales seem smaller.
Original NASA ASRS Text
Title: A WDB 3-ENG TRANSPORT ON TKOF ROLL EXCEEDED EXHAUST GAS TEMP LIMITS ON #2 AND #3 ENGS. MAINT ADVISED TEMPS RECORDED NOT OUT OF MAINT MANUAL LIMITS.
Narrative: JUST PRIOR TO ROTATION ON TKOF, NOTICED #2 ENG EGT EXCEEDING REDLINE. REDUCED THRUST ON THAT ENG. AFTER ROTATION, NOTICED #3 ENG EGT EXCEEDING REDLINE. REDUCED THRUST ON THAT ENG. ON CLBOUT, VIEWED SNAPSHOT ON ELECTRONIC ENG INDICATING SYS (EIDS) AND NOTED EXCEEDENCES AND DURATION. ADVISED DISPATCH AND MAINT CTL OF READINGS AND WERE ADVISED THAT NO CRITICAL EXCEEDENCES OCCURRED, AND THAT WE WERE OK TO CONTINUE TO SEA. RECORDED EXCEEDENCES AND DURATION IN ACFT MAINT LOGBOOK. OUR COMPANY SOP IS FOR THE PF TO SET TKOF THRUST BY 80 KTS AND FOR THE PNF, TO VERIFY THAT THE CORRECT THRUST IS SET BY 80 KTS. I WAS FLYING, AND AFTER I INITIALLY SET TKOF THRUST, I TOOK MY HAND TEMPORARILY OFF THE THROTTLES, AND THE FO READJUSTED THE PWR TO A MORE EXACT SETTING. PRIOR TO ROTATION, I GLANCED DOWN AT THE PWR SETTINGS AND CALLED OUT THE OVERTEMP. THE FO FELT THAT HE HAD ACCURATELY ADJUSTED THE PWR, AND THAT THE EPR'S BLOOMED TO A SLIGHTLY HIGHER SETTING AFTERWARDS. MY ATTN WAS FOCUSED MORE OUTSIDE THE ACFT, AS WE HAD A XWIND ON TKOF. THE FO ALSO COMMENTED THAT HE FELT THAT THE NEW EIDS IS HARDER TO READ, AS THE SCALES SEEM SMALLER.
