Narrative:

I was working local control east, when ground taxied a SHD6 X to runway 18L for a wbound departure. I requested a release from local control west for a 270 degree heading and approval was given. I cleared the SHD6 for takeoff to fly a 270 degree heading. I watched the SHD6 start a right turn, started to say contact departure, when I saw a FK28 Y rotating on runway 18R south of mid field. I issued traffic, 12 O'clock departing parallel runway, no factor, it appeared to me as though the SHD6 would pass behind the FK28). The SHD6 pilot took evasive action -- a left turn paralleling the jet departure. The local west controller, I had forgotten about the traffic released on the parallel runway, and launched a departure which conflicted with the SHD6. Routinely, at charlotte, aircraft are taxied to runways for convenience of the operator to save taxi times, as in this situation. This could have been prevented by using a runway that procedures state, additionally, if a visual reminder was in place to warn the local control west (or remind) of the released aircraft.

Title: MULTIPLE RWY OP PARALLEL RWYS, ACR X HAD NMAC, LTSS FROM ACR Y DEPARTING ON PARALLEL RWY. SYS ERROR. EVASIVE ACTION TAKEN.

Narrative: I WAS WORKING LCL CTL E, WHEN GND TAXIED A SHD6 X TO RWY 18L FOR A WBOUND DEP. I REQUESTED A RELEASE FROM LCL CTL W FOR A 270 DEG HDG AND APPROVAL WAS GIVEN. I CLRED THE SHD6 FOR TKOF TO FLY A 270 DEG HDG. I WATCHED THE SHD6 START A R TURN, STARTED TO SAY CONTACT DEP, WHEN I SAW A FK28 Y ROTATING ON RWY 18R S OF MID FIELD. I ISSUED TFC, 12 O'CLOCK DEPARTING PARALLEL RWY, NO FACTOR, IT APPEARED TO ME AS THOUGH THE SHD6 WOULD PASS BEHIND THE FK28). THE SHD6 PLT TOOK EVASIVE ACTION -- A L TURN PARALLELING THE JET DEP. THE LCL W CTLR, I HAD FORGOTTEN ABOUT THE TFC RELEASED ON THE PARALLEL RWY, AND LAUNCHED A DEP WHICH CONFLICTED WITH THE SHD6. ROUTINELY, AT CHARLOTTE, ACFT ARE TAXIED TO RWYS FOR CONVENIENCE OF THE OPERATOR TO SAVE TAXI TIMES, AS IN THIS SIT. THIS COULD HAVE BEEN PREVENTED BY USING A RWY THAT PROCS STATE, ADDITIONALLY, IF A VISUAL REMINDER WAS IN PLACE TO WARN THE LCL CTL W (OR REMIND) OF THE RELEASED ACFT.
