Narrative:
Local control requested opp direction departure for air carrier X which approach control approved. Traffic was inbound on ILS and was thought to be enough room for the departure. When departure control worked the aircraft, they perceived the target to be straight out rather than 255 degrees as assigned. Departure turned the aircraft nwbnd to avoid the conflict. The departing aircraft was heavy, WX was hot and the turn was slow. The approach controller could have given more room. Everything should have been coordinated better. Traffic should have held on the ground since the arrival was last one. Approach control should have pulled the inbound aircraft out. There resulted less than standard separation. Supplemental information from acn 116263: air carrier X required a runway for departure that was opp direction to the flow of all other traffic. Coordination was accomplished with approach controller. Tower controller failed to provide sufficient sep. Approach controller could have provided a better interval to accommodate the operation. Supplemental information from acn 116502: I was working departure control. Tower launched a runway 27L departure while approach had a runway 9R arrival. Tower should not have launched the air carrier X and/or approach should not have turned air carrier Y in. I was caught in the middle, took evasive action. Supplemental information from acn 116264: approach control was very uninformed of entire operation. Our vigilance was extreme looking for traffic in climb. Visibility contact obtained inside the marker. We had extreme wake turbulence at 1000' above ground level. Very unsafe operation!!! Air carrier X should never have been cleared for takeoff, or we should have been given a delay for the approach.

Title: AN ACR WDB WAS CLEARED FOR TKOF ON OPPOSITE RWY AND CONFLICTED WITH AN ACR ON APCH INSIDE THE OUTER MARKER.
Narrative: LCL CTL REQUESTED OPP DIRECTION DEP FOR ACR X WHICH APCH CTL APPROVED. TFC WAS INBND ON ILS AND WAS THOUGHT TO BE ENOUGH ROOM FOR THE DEP. WHEN DEP CTL WORKED THE ACFT, THEY PERCEIVED THE TARGET TO BE STRAIGHT OUT RATHER THAN 255 DEGS AS ASSIGNED. DEP TURNED THE ACFT NWBND TO AVOID THE CONFLICT. THE DEPARTING ACFT WAS HEAVY, WX WAS HOT AND THE TURN WAS SLOW. THE APCH CTLR COULD HAVE GIVEN MORE ROOM. EVERYTHING SHOULD HAVE BEEN COORDINATED BETTER. TFC SHOULD HAVE HELD ON THE GND SINCE THE ARR WAS LAST ONE. APCH CTL SHOULD HAVE PULLED THE INBND ACFT OUT. THERE RESULTED LESS THAN STANDARD SEPARATION. SUPPLEMENTAL INFO FROM ACN 116263: ACR X REQUIRED A RWY FOR DEP THAT WAS OPP DIRECTION TO THE FLOW OF ALL OTHER TFC. COORD WAS ACCOMPLISHED WITH APCH CTLR. TWR CTLR FAILED TO PROVIDE SUFFICIENT SEP. APCH CTLR COULD HAVE PROVIDED A BETTER INTERVAL TO ACCOMMODATE THE OPERATION. SUPPLEMENTAL INFO FROM ACN 116502: I WAS WORKING DEP CTL. TWR LAUNCHED A RWY 27L DEP WHILE APCH HAD A RWY 9R ARR. TWR SHOULD NOT HAVE LAUNCHED THE ACR X AND/OR APCH SHOULD NOT HAVE TURNED ACR Y IN. I WAS CAUGHT IN THE MIDDLE, TOOK EVASIVE ACTION. SUPPLEMENTAL INFO FROM ACN 116264: APCH CTL WAS VERY UNINFORMED OF ENTIRE OPERATION. OUR VIGILANCE WAS EXTREME LOOKING FOR TFC IN CLB. VIS CONTACT OBTAINED INSIDE THE MARKER. WE HAD EXTREME WAKE TURB AT 1000' ABOVE GND LEVEL. VERY UNSAFE OPERATION!!! ACR X SHOULD NEVER HAVE BEEN CLRED FOR TKOF, OR WE SHOULD HAVE BEEN GIVEN A DELAY FOR THE APCH.
