Narrative:

On wed/march at clt everything was routine through engine start and taxi. We were told to taxi to runway 36L by 'M' hold short of 'east.' at east we were told to taxi to runway 36L. We were about #3 in line when we arrived at the end of 36L. When we were next to go at the end of 36L about pm:45 a transmission was made by tower which sounded like 'air carrier axy expedite going into position and hold on 36L.' the copilot repeated back to tower 'air carrier axy into position and hold 36L.' upon crossing the hold line tower gave a commuter clearance for takeoff from the intersection just short of the end taxiway on 36L. The commuters call sign ended in xy. At this point I felt the tower did not intend for us to be over the hold line. I stopped short of the runway because I felt there was confusion on who was cleared into position. I told tower I was over the hold line and they sent the aircraft on final around. We were cleared into position and a normal takeoff made when cleared by tower. Hold short lights should help stop these missed communication.

Title: RWY INCURSION.

Narrative: ON WED/MARCH AT CLT EVERYTHING WAS ROUTINE THROUGH ENG START AND TAXI. WE WERE TOLD TO TAXI TO RWY 36L BY 'M' HOLD SHORT OF 'E.' AT E WE WERE TOLD TO TAXI TO RWY 36L. WE WERE ABOUT #3 IN LINE WHEN WE ARRIVED AT THE END OF 36L. WHEN WE WERE NEXT TO GO AT THE END OF 36L ABOUT PM:45 A XMISSION WAS MADE BY TWR WHICH SOUNDED LIKE 'ACR AXY EXPEDITE GOING INTO POS AND HOLD ON 36L.' THE COPLT REPEATED BACK TO TWR 'ACR AXY INTO POS AND HOLD 36L.' UPON XING THE HOLD LINE TWR GAVE A COMMUTER CLRNC FOR TKOF FROM THE INTXN JUST SHORT OF THE END TAXIWAY ON 36L. THE COMMUTERS CALL SIGN ENDED IN XY. AT THIS POINT I FELT THE TWR DID NOT INTEND FOR US TO BE OVER THE HOLD LINE. I STOPPED SHORT OF THE RWY BECAUSE I FELT THERE WAS CONFUSION ON WHO WAS CLRED INTO POS. I TOLD TWR I WAS OVER THE HOLD LINE AND THEY SENT THE ACFT ON FINAL AROUND. WE WERE CLRED INTO POS AND A NORMAL TKOF MADE WHEN CLRED BY TWR. HOLD SHORT LIGHTS SHOULD HELP STOP THESE MISSED COM.
