Narrative:
During maximum power takeoff from hnl, outside air temperature of 31 degree C, power setting of 113.3 N1. During acceleration, flight engineer noted engine temperatures rising toward limits. He started to reduce power. As high-temperature lights came on, he continued to reduce power to approximately 108.5 N1. First officer called 120 KTS. Captain noted temperature on an engine of 967 degree C and 961 degree C on another engine. Captain elected to continue takeoff as safest course of action due to danger of heavy weight/high speed abort. After takeoff, crew referred to DC10 operating manual and temperatures allowed for continuation of flight and normal operation of all engines, section 20 page 3 of -30 supplement. Remainder of flight was normal. Note: crews could be confused by numbers in powerplant abnormals for -10 series. Suggest combining both charts in powerplant as in limitations.

Title: AN ACR DC10-30 CREW HAD 2 ENGS, OR MORE, OVERTEMP ON TKOF. WX FACTORS HIGH AMBIENT TEMP. ACFT EQUIP PROB ENG OVERTEMP WITHIN LIMITS.
Narrative: DURING MAX PWR TKOF FROM HNL, OUTSIDE AIR TEMP OF 31 DEG C, PWR SETTING OF 113.3 N1. DURING ACCELERATION, FE NOTED ENG TEMPS RISING TOWARD LIMITS. HE STARTED TO REDUCE PWR. AS HIGH-TEMP LIGHTS CAME ON, HE CONTINUED TO REDUCE PWR TO APPROX 108.5 N1. FO CALLED 120 KTS. CAPT NOTED TEMP ON AN ENG OF 967 DEG C AND 961 DEG C ON ANOTHER ENG. CAPT ELECTED TO CONTINUE TKOF AS SAFEST COURSE OF ACTION DUE TO DANGER OF HVY WT/HIGH SPD ABORT. AFTER TKOF, CREW REFERRED TO DC10 OPERATING MANUAL AND TEMPS ALLOWED FOR CONTINUATION OF FLT AND NORMAL OP OF ALL ENGS, SECTION 20 PAGE 3 OF -30 SUPPLEMENT. REMAINDER OF FLT WAS NORMAL. NOTE: CREWS COULD BE CONFUSED BY NUMBERS IN POWERPLANT ABNORMALS FOR -10 SERIES. SUGGEST COMBINING BOTH CHARTS IN POWERPLANT AS IN LIMITATIONS.
