CAPT OF AN MLG QUESTIONS HIS JUDGEMENT IN ACCEPTING AN EXPEDITED TKOF CLRNC FROM TWR SINCE THE FLC MAY MISS SOMETHING IMPORTANT BEFORE TKOF.

Narrative

ORD TWR WAS DEPARTING ACFT ON RWY 22L AND ARR ACFT ON RWY 27L. WE WERE TAXIING ON TXWY D BEHIND A DC10 TOWARDS RWY 22L ON ORD TWR FREQ. THE DC10 WAS NOT READY FOR TKOF AND WAS TOLD TO PULL INTO THE RUN-UP PAD. TWR TOLD US TO CONTINUE TO THE RWY HE WAS GOING TO GET US RIGHT OUT. AS WE APCHED RWY 22L; THE TWR CTLR POINTED OUT ARR TFC 2 MI OUT ON RWY 27L. HE TOLD US TO KEEP IT ROLLING AND CLRED US FOR TKOF ON RWY 22L; REFERENCE THE LNDG TFC 2.0 MI OUT FOR RWY 27L; OR IF WE COULDN'T KEEP IT ROLLING TO HOLD SHORT OF RWY 22L. WE ACCEPTED THE TKOF CLRNC AND KEPT THE ACFT ROLLING AND DEPARTED RWY 22L. THE SEQUENCING APPEARED TO WORK OK BUT ON THINKING ABOUT IT FURTHER; LATER IN THE FLT; IT PROBABLY WOULD HAVE BEEN MORE PRUDENT TO HOLD SHORT AND NOT ACCEPT THE TKOF CLRNC. ORD DOES AN EXCELLENT JOB OF SEQUENCING TFC. IT WAS THE LAST LEG OF A 3 DAY TRIP; WE WERE THINKING WE WERE HELPING THE CTLR OUT; HE WAS PROBABLY THINKING HE WAS DOING US A FAVOR HELPING TO GET US OUT MORE QUICKLY. AND IN HINDSIGHT I WOULDN'T ACCEPT THAT CLRNC AGAIN; AS IT WAS BELOW MY PERSONAL COMFORT FACTOR.
