Narrative:
We had to abort our takeoff roll because another aircraft had failed to hold short of our runway at approximately midfield. Aircraft speed was approximately 90-100 KTS at the time the throttles were closed. The deceleration was similar to a normal landing roll out. The captain did not feel that brake overheating was a problem but said to check it to make sure. I had the book in my lap and was twice interrupted by radio xmissions while trying to check the brake energy chart. Ground control expedited us back to the runway and before we had time to check the charts for brake heating we were cleared for takeoff. The captain elected to depart. I had no real problem with that. We departed uneventfully. While en route we checked the brake energy chart and found that if you entered the chart using the brake temperature indicator, 10 mins of cooling were required. If you entered the chart using gross weight, speed and OAT, you were well within the safety zone of no cooling required. I feel this is a typical example of a two man crew trying to operate in the same time frame that we are used to as a three man crew. It doesn't work. You get overloaded. I feel we should have pulled off somewhere caught our breath and to hell with the schedule.
Original NASA ASRS Text
Title: ACR WDB ABORTS TKOF AS LNDG TRAFFIC FAILS TO HOLD SHORT OF PARALLEL RWY ON ROLL OUT. WDB FLT CREW FAILED TO THOROUGHLY CHECK BRAKE ENERGY CHARTS FOR ANY GND DELAY REQUIRED AND MADE AN EXPEDITED DEP AFTER TAXI BACK.
Narrative: WE HAD TO ABORT OUR TKOF ROLL BECAUSE ANOTHER ACFT HAD FAILED TO HOLD SHORT OF OUR RWY AT APPROX MIDFIELD. ACFT SPD WAS APPROX 90-100 KTS AT THE TIME THE THROTTLES WERE CLOSED. THE DECELERATION WAS SIMILAR TO A NORMAL LNDG ROLL OUT. THE CAPT DID NOT FEEL THAT BRAKE OVERHEATING WAS A PROB BUT SAID TO CHK IT TO MAKE SURE. I HAD THE BOOK IN MY LAP AND WAS TWICE INTERRUPTED BY RADIO XMISSIONS WHILE TRYING TO CHK THE BRAKE ENERGY CHART. GND CTL EXPEDITED US BACK TO THE RWY AND BEFORE WE HAD TIME TO CHK THE CHARTS FOR BRAKE HEATING WE WERE CLRED FOR TKOF. THE CAPT ELECTED TO DEPART. I HAD NO REAL PROB WITH THAT. WE DEPARTED UNEVENTFULLY. WHILE ENRTE WE CHKED THE BRAKE ENERGY CHART AND FOUND THAT IF YOU ENTERED THE CHART USING THE BRAKE TEMP INDICATOR, 10 MINS OF COOLING WERE REQUIRED. IF YOU ENTERED THE CHART USING GROSS WT, SPD AND OAT, YOU WERE WELL WITHIN THE SAFETY ZONE OF NO COOLING REQUIRED. I FEEL THIS IS A TYPICAL EXAMPLE OF A TWO MAN CREW TRYING TO OPERATE IN THE SAME TIME FRAME THAT WE ARE USED TO AS A THREE MAN CREW. IT DOESN'T WORK. YOU GET OVERLOADED. I FEEL WE SHOULD HAVE PULLED OFF SOMEWHERE CAUGHT OUR BREATH AND TO HELL WITH THE SCHEDULE.
