Narrative:

Last day of four days of flying - last leg bna - ord. Previously landed on runway 02C. At departure ATIS stated bna using runways 2L,2C and 2R. Company information showed the same runways and we talked about us usually using runway 02L for departures. Our mindset was for runway 02L. We contacted ground at spot 5. We thought he said 'tango 5 taxi to runway 02L.' my copilot insists that he read back 'tango 5 cross runway 31 taxi to runway 02L.' as we taxied forward the controller asked 'do you have lima.' we took that to mean do you have lima ATIS information. We responded 'yes,' as we were about to ask for it on ACARS. He may have meant taxiway lima. Just as I crossed runway 31 the controller said 'arc X you missed your turn.' I stopped the aircraft on the parallel taxiway on the other side of runway 31 and asked the ground controller what runway he had cleared us to. He stated 'runway 31.' luckily there were no aircraft landing or taking off on runway 31 at the time of my crossing. Callback conversation with reporter revealed the following information: reporter states that both he and the first officer thought they heard clearance to runway 2L. ATIS had stated that runways 2L, 2C, and 2R were in use. No mention of runway 31. The only other clearance he heard was for another air carrier to taxi to runway 31 which is fairly normal. Controller may have thought he cleared both aircraft to runway 31. Flight crew believes not, and the normal departure runway is 2L. He does however, accept the blame as he may have had a mind set regarding what was normal. To this day reporter believes they heard runway 2L. Reporter believes that a return to standard phraseology would help to alleviate such problems. If controller had asked 'do you have information lima?' or do you have taxiway lima, there would have been no confusion and the problem would have been straightened out right then.

Title: FLT CREW OF AN F100 IS CLRED TO TAXI AND THEY BELIEVE CLRNC IS FOR RWY 02L. AS THEY TAXI OUT CTLR ASKS IF THEY HAVE 'LIMA.' BELIEVING THE QUESTION IS REGARDING THE ATIS, THEY ANSWER YES. GND THEN TELLS THEM THEY MISSED THEIR TURN AFTER THEY HAVE CROSSED AN ACTIVE RWY.

Narrative: LAST DAY OF FOUR DAYS OF FLYING - LAST LEG BNA - ORD. PREVIOUSLY LANDED ON RWY 02C. AT DEP ATIS STATED BNA USING RWYS 2L,2C AND 2R. COMPANY INFO SHOWED THE SAME RWYS AND WE TALKED ABOUT US USUALLY USING RWY 02L FOR DEPS. OUR MINDSET WAS FOR RWY 02L. WE CONTACTED GND AT SPOT 5. WE THOUGHT HE SAID 'TANGO 5 TAXI TO RWY 02L.' MY COPLT INSISTS THAT HE READ BACK 'TANGO 5 CROSS RWY 31 TAXI TO RWY 02L.' AS WE TAXIED FORWARD THE CONTROLLER ASKED 'DO YOU HAVE LIMA.' WE TOOK THAT TO MEAN DO YOU HAVE LIMA ATIS INFO. WE RESPONDED 'YES,' AS WE WERE ABOUT TO ASK FOR IT ON ACARS. HE MAY HAVE MEANT TXWY LIMA. JUST AS I CROSSED RWY 31 THE CTLR SAID 'ARC X YOU MISSED YOUR TURN.' I STOPPED THE ACFT ON THE PARALLEL TXWY ON THE OTHER SIDE OF RWY 31 AND ASKED THE GND CTLR WHAT RWY HE HAD CLRED US TO. HE STATED 'RWY 31.' LUCKILY THERE WERE NO ACFT LNDG OR TAKING OFF ON RWY 31 AT THE TIME OF MY CROSSING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT BOTH HE AND THE FO THOUGHT THEY HEARD CLRNC TO RWY 2L. ATIS HAD STATED THAT RWYS 2L, 2C, AND 2R WERE IN USE. NO MENTION OF RWY 31. THE ONLY OTHER CLRNC HE HEARD WAS FOR ANOTHER ACR TO TAXI TO RWY 31 WHICH IS FAIRLY NORMAL. CTLR MAY HAVE THOUGHT HE CLRED BOTH ACFT TO RWY 31. FLT CREW BELIEVES NOT, AND THE NORMAL DEP RWY IS 2L. HE DOES HOWEVER, ACCEPT THE BLAME AS HE MAY HAVE HAD A MIND SET REGARDING WHAT WAS NORMAL. TO THIS DAY RPTR BELIEVES THEY HEARD RWY 2L. RPTR BELIEVES THAT A RETURN TO STANDARD PHRASEOLOGY WOULD HELP TO ALLEVIATE SUCH PROBS. IF CTLR HAD ASKED 'DO YOU HAVE INFO LIMA?' OR DO YOU HAVE TXWY LIMA, THERE WOULD HAVE BEEN NO CONFUSION AND THE PROB WOULD HAVE BEEN STRAIGHTENED OUT RIGHT THEN.
