Narrative:
Was told by tower that runway 14L at taxiway U was full length; take off was normal; however data shows 10005 ft. A NOTAM later found showed 7310 ft available at taxiway U. Correct airplane performance data.callback conversation with reporter revealed the following information: the reporter clarified that the airport in question was ord and stated that significant delays had occurred that day. The available runway appeared sufficient even though it did not appear that the company reported length was available. The tower could have been more helpful.
