Narrative:
Thunderstorms were moving into atl from the west. Ground taxied us between runways to expedite our departure as wbounds were shut down. Asked if we could depart from B2 on runway 8R, 9800 ft available. As the runway is 10000 ft I indicated yes. At this point we requested takeoff performance data, but as we took the active none was available for an intersection takeoff. I elected to proceed with maximum power, accompanied by a headwind, as I felt safety wasn't an issue. We departed. Had we elected to go full length, the delay would have been at least 20 mins. Had the WX moved in, it would have been longer. We also had international connections at ord. My copilot also concurred that, while not operating with a takeoff performance data from B2, 200 ft less than full length was not a safety issue. Another minor issue was fuel. Had we elected to stay, lack of adequate arrival fuel may have caused us to go back to the gate. Supplemental information from acn 471760: the runway limit was 157400 pounds, our takeoff weight was 126500 pounds. 8 KTS of headwind with WX approaching from the west. It would be an hour before we could get off. Myself and the captain saw no problem taking this, in the interest of safety.

Title: ACR CREW ELECTS TO DEPART WITHOUT TKOF PERFORMANCE NUMBERS FOR THE RWY LENGTH TO BE USED.
Narrative: TSTMS WERE MOVING INTO ATL FROM THE W. GND TAXIED US BTWN RWYS TO EXPEDITE OUR DEP AS WBOUNDS WERE SHUT DOWN. ASKED IF WE COULD DEPART FROM B2 ON RWY 8R, 9800 FT AVAILABLE. AS THE RWY IS 10000 FT I INDICATED YES. AT THIS POINT WE REQUESTED TKOF PERFORMANCE DATA, BUT AS WE TOOK THE ACTIVE NONE WAS AVAILABLE FOR AN INTXN TKOF. I ELECTED TO PROCEED WITH MAX PWR, ACCOMPANIED BY A HEADWIND, AS I FELT SAFETY WASN'T AN ISSUE. WE DEPARTED. HAD WE ELECTED TO GO FULL LENGTH, THE DELAY WOULD HAVE BEEN AT LEAST 20 MINS. HAD THE WX MOVED IN, IT WOULD HAVE BEEN LONGER. WE ALSO HAD INTL CONNECTIONS AT ORD. MY COPLT ALSO CONCURRED THAT, WHILE NOT OPERATING WITH A TKOF PERFORMANCE DATA FROM B2, 200 FT LESS THAN FULL LENGTH WAS NOT A SAFETY ISSUE. ANOTHER MINOR ISSUE WAS FUEL. HAD WE ELECTED TO STAY, LACK OF ADEQUATE ARR FUEL MAY HAVE CAUSED US TO GO BACK TO THE GATE. SUPPLEMENTAL INFO FROM ACN 471760: THE RWY LIMIT WAS 157400 LBS, OUR TKOF WT WAS 126500 LBS. 8 KTS OF HEADWIND WITH WX APCHING FROM THE W. IT WOULD BE AN HR BEFORE WE COULD GET OFF. MYSELF AND THE CAPT SAW NO PROB TAKING THIS, IN THE INTEREST OF SAFETY.
