B190 FLT CREW ABORTED TKOF AS ATC GAR INSTRUCTION TO AN ARR ACFT WAS MISUNDERSTOOD.

Narrative

WE WERE TOLD TO POS AND HOLD ON RWY 36L; BE READY FOR IMMEDIATE DEP; DASH 8 ON 3 MI FINAL. AFTER JUST TURNING ACFT TO FACE CTRLINE ON RWY; WE WERE CLRED FOR TKOF RWY 36L NO DELAY; ARRIVING TFC. AT ABOUT 60 KTS; THE TWR SAID SOMETHING TO THE EFFECT: (XMISSION WAS NOT LOUD AND CLR AND COCKPIT NOISE LEVEL WAS LOUD WITH FULL PWR AND CREW CALLOUTS BEING MADE) 'ACR X; YOU NEED TO TAKE OFF IMMEDIATELY OR ABORT TKOF.' FO (PF) HEARD 'ACR X...ABORT.' FO ABORTED TKOF. IT WOULD BE BEST FOR ATC NOT TO CONTACT US DURING TKOF ROLL UNLESS FOR AN EMER. IF AN EMER (IE; HERD OF DEER DOWN THE RWY); ATC SHOULD MAKE A BRIEF STATEMENT LIKE; 'ACR X FLT XXX ABORT TKOF IF ABLE ABORT.' IN THIS CASE; I FEEL ATC SHOULD HAVE LET US CONTINUE TKOF UNINTERRUPTED AND HAD THE DASH 8 GO AROUND. SUPPLEMENTAL INFO FROM ACN 654857: WHEN RELEASED; CTLRS TOLD ACFT BEHIND US TO GO AROUND. BEING PF; I WAS LISTENING FOR ADDITIONAL INSTRUCTIONS FROM CAPT AND CTLRS. SUDDENLY HEARD CTLR TELL ME WHAT WAS INTERPED AS THE REQUEST TO ABORT TKOF. CAPT SAID TO CONTINUE AND INFORMED HIM ABOUT WHAT I HEARD TWR SAY. CONFUSION EXISTED BECAUSE OF POOR COM.
