Narrative:

After push-back and start of #3 engine, we started #1 engine. Winds were calm and the OAT was 45 degree F. Egt climbed steadily to 350 degree C during the start. I checked it closely to determine if we'd really had a hot start, noted that the temperature actually was right at 350 degree C (a hot start) called for a shut down. Temperature actually climbed to 380 degree C before starting to come back down. Followed all SOP's, called cgr ord line maintenance. Returned to the gate and got another aircraft. I can think of no contributing factors or ways to improve on our performance, hot starts do happen. It was a close call and a slow but steady rise in egt -- not a classic hot start, ie, high fuel flow/quick egt rise, at all. Better gauges markings, ie, hot start red lines on the egt gauges might be helpful in more precise noting of a hot start, especially night, in a dark cockpit, such as we had that night.

Title: ACR LGT ACFT JET ENG HOT START.

Narrative: AFTER PUSH-BACK AND START OF #3 ENG, WE STARTED #1 ENG. WINDS WERE CALM AND THE OAT WAS 45 DEG F. EGT CLBED STEADILY TO 350 DEG C DURING THE START. I CHKED IT CLOSELY TO DETERMINE IF WE'D REALLY HAD A HOT START, NOTED THAT THE TEMP ACTUALLY WAS RIGHT AT 350 DEG C (A HOT START) CALLED FOR A SHUT DOWN. TEMP ACTUALLY CLBED TO 380 DEG C BEFORE STARTING TO COME BACK DOWN. FOLLOWED ALL SOP'S, CALLED CGR ORD LINE MAINT. RETURNED TO THE GATE AND GOT ANOTHER ACFT. I CAN THINK OF NO CONTRIBUTING FACTORS OR WAYS TO IMPROVE ON OUR PERFORMANCE, HOT STARTS DO HAPPEN. IT WAS A CLOSE CALL AND A SLOW BUT STEADY RISE IN EGT -- NOT A CLASSIC HOT START, IE, HIGH FUEL FLOW/QUICK EGT RISE, AT ALL. BETTER GAUGES MARKINGS, IE, HOT START RED LINES ON THE EGT GAUGES MIGHT BE HELPFUL IN MORE PRECISE NOTING OF A HOT START, ESPECIALLY NIGHT, IN A DARK COCKPIT, SUCH AS WE HAD THAT NIGHT.
