An air carrier MD80 super 80 flight crew took off on runway 36R and turned to their assigned heading of 345 degrees and at the same time a commuter turboprop took off from runway 36L and maintained runway heading. The aircraft passed within several hundred ft of each other at low altitude.

Narrative:
The dfw west tower issued us clearance to takeoff on runway 36R and to fly heading 345 degrees. At some point during our takeoff roll the tower also issued a takeoff clearance to an air carrier commuter turboprop on runway 36L. Upon reaching 300 ft AGL, we turned to the assigned heading of 345 degrees. During the turn the captain said he thought he saw an aircraft fly directly beneath us. Seconds later at 700 ft AGL, we got a TCASII warning to monitor vertical speed which I did by continuing the climb at takeoff power and flaps 11 degrees. At about 1500 ft AGL we received a clear of conflict. When the captain asked the tower about issuing a clearance for one takeoff aircraft to turn in front of another, the tower responded they did every day. This is an unacceptable, unsafe procedure inviting disaster. I don't know if the commuter crew saw us, but if he didn't and we lost an engine the potential for a midair is enormous. There are also wake turbulence considerations for the turboprop. I believe this procedure needs to be reviewed immediately and modified to prevent a disaster from happening in the future.
Original NASA ASRS Text
Title: AN ACR MD80 SUPER 80 FLC TOOK OFF ON RWY 36R AND TURNED TO THEIR ASSIGNED HDG OF 345 DEGS AND AT THE SAME TIME A COMMUTER TURBOPROP TOOK OFF FROM RWY 36L AND MAINTAINED RWY HDG. THE ACFT PASSED WITHIN SEVERAL HUNDRED FT OF EACH OTHER AT LOW ALT.
Narrative: THE DFW WEST TWR ISSUED US CLRNC TO TKOF ON RWY 36R AND TO FLY HDG 345 DEGS. AT SOME POINT DURING OUR TKOF ROLL THE TWR ALSO ISSUED A TKOF CLRNC TO AN ACR COMMUTER TURBOPROP ON RWY 36L. UPON REACHING 300 FT AGL, WE TURNED TO THE ASSIGNED HDG OF 345 DEGS. DURING THE TURN THE CAPT SAID HE THOUGHT HE SAW AN ACFT FLY DIRECTLY BENEATH US. SECONDS LATER AT 700 FT AGL, WE GOT A TCASII WARNING TO MONITOR VERT SPD WHICH I DID BY CONTINUING THE CLB AT TKOF PWR AND FLAPS 11 DEGS. AT ABOUT 1500 FT AGL WE RECEIVED A CLR OF CONFLICT. WHEN THE CAPT ASKED THE TWR ABOUT ISSUING A CLRNC FOR ONE TKOF ACFT TO TURN IN FRONT OF ANOTHER, THE TWR RESPONDED THEY DID EVERY DAY. THIS IS AN UNACCEPTABLE, UNSAFE PROC INVITING DISASTER. I DON'T KNOW IF THE COMMUTER CREW SAW US, BUT IF HE DIDN'T AND WE LOST AN ENG THE POTENTIAL FOR A MIDAIR IS ENORMOUS. THERE ARE ALSO WAKE TURB CONSIDERATIONS FOR THE TURBOPROP. I BELIEVE THIS PROC NEEDS TO BE REVIEWED IMMEDIATELY AND MODIFIED TO PREVENT A DISASTER FROM HAPPENING IN THE FUTURE.
