CTLR RELEASED A DC3 EXPECTING THE ACFT TO FLY EBOUND; THEN RELEASED A B727 NBOUND ON ANOTHER RWY. THE DC3 TURNED L 2 MI E OF THE ARPT REQUIRING THE B727 TO TAKE EVASIVE ACTION BY TURNING L. THE CTLR CLAIMS THAT A NEW STRIP DISPLAY SYS CONTRIBUTED TO THE ROUTING CONFUSION.

Narrative

DUE TO SOME CONFUSION AT THE LCL POS WITH A NEW STRIP DISPLAY SYS; A DC3 WAS DEPARTED FROM RWY 10. THE LCL CTLR OBSERVED THE DC3 ON EBOUND HDG; 2 MI E; THEN DEPARTED A BE18 SAME RWY EBOUND BY STATING THAT ACFT AHEAD IS ALSO EBOUND. THE LCL CTLR OBSERVED DEP CORRIDOR RWY 8 CLR AND DEPARTED B727 OFF RWY 8 NBOUND. THE B727 PLT ON TKOF CLB OBSERVED DC3 OFF HIS R MAKE A L TURN SO THE B727 PLT INITIATED HIS L TURN EARLIER THAN EXPECTED TO KEEP THE DC3 IN SIGHT. THE DC3 PLT OBSERVED THE B727 TURN L AND KEPT HIS COURSE PARALLEL TO THE B727. RADAR AND VFR SEPARATION WAS MAINTAINED. SUGGESTION TO PREVENT SIMILAR ACTION FROM RECURRING; EVEN THOUGH SEPARATION WAS MAINTAINED. LCL CTLR SHOULD MAKE ABSOLUTELY SURE ALL INFO ON ACFT IS DISPLAYED AND CHKED PRIOR TO ISSUING A TKOF CLRNC SINCE THE DC3 WAS ON A WBOUND FLT PLAN EVEN THOUGH HE FLEW 2 MI E PRIOR TO COMMENCING HIS L TURN. ALSO; IT WOULD BE A SAFE PRACTICE FOR PLTS TO ADVISE ATC THAT THEY ARE TURNING WHEN THEIR RTE OF FLT CROSSES THE DEP END OF ANOTHER RWY.
