Narrative:

After receiving position and hold clearance, tower controller told us it would be a couple of mins before he could clear us for takeoff due to en route sep. Within 1-1 1/2 mins, we were cleared for takeoff. On initial climb and at approximately 400' AGL we saw a small aircraft sing engine at about our altitude and headed directly toward us, out the right side window. We continued the departure and asked tower what the traffic was doing there, and did he know it was there? After a couple of attempts to get a response, he reported that the aircraft (small aircraft) had departed 36R and had us in sight. Since no evasive action was required, I waited to talk to a supervisor on the phone later that evening. His explanation was that when a swbnd GA aircraft departed at the same time as an air carrier, the small aircraft is given a 270 degree heading behind the jet after he reports the jet in sight. This was 'standard procedure.' standard or not, the aircraft was entirely too close to us. Evidently standard procedure was not used because it would not be possible for an small aircraft and a jet to depart at the same time and the small aircraft heading 270 degrees at 400' at the same time we are 400'. I believe he was cleared first and was given a 270 degree turn while we were in position. I believe the tower controller on 36L was watching on en route spacing, got the spacing and cleared us for takeoff, forgetting about the other aircraft or not knowing about him. Better coordination between local controller might have not let this happen.

Title: SMA DEPARTS 36R, TURNS TO 270 DEGREES AND CONFLICTS WITH ACR OFF 36L.

Narrative: AFTER RECEIVING POS AND HOLD CLRNC, TWR CTLR TOLD US IT WOULD BE A COUPLE OF MINS BEFORE HE COULD CLR US FOR TKOF DUE TO ENRTE SEP. WITHIN 1-1 1/2 MINS, WE WERE CLRED FOR TKOF. ON INITIAL CLB AND AT APPROX 400' AGL WE SAW A SMA SING ENG AT ABOUT OUR ALT AND HEADED DIRECTLY TOWARD US, OUT THE RIGHT SIDE WINDOW. WE CONTINUED THE DEP AND ASKED TWR WHAT THE TFC WAS DOING THERE, AND DID HE KNOW IT WAS THERE? AFTER A COUPLE OF ATTEMPTS TO GET A RESPONSE, HE RPTED THAT THE ACFT (SMA) HAD DEPARTED 36R AND HAD US IN SIGHT. SINCE NO EVASIVE ACTION WAS REQUIRED, I WAITED TO TALK TO A SUPVR ON THE PHONE LATER THAT EVENING. HIS EXPLANATION WAS THAT WHEN A SWBND GA ACFT DEPARTED AT THE SAME TIME AS AN ACR, THE SMA IS GIVEN A 270 DEG HDG BEHIND THE JET AFTER HE RPTS THE JET IN SIGHT. THIS WAS 'STANDARD PROC.' STANDARD OR NOT, THE ACFT WAS ENTIRELY TOO CLOSE TO US. EVIDENTLY STANDARD PROC WAS NOT USED BECAUSE IT WOULD NOT BE POSSIBLE FOR AN SMA AND A JET TO DEPART AT THE SAME TIME AND THE SMA HDG 270 DEGS AT 400' AT THE SAME TIME WE ARE 400'. I BELIEVE HE WAS CLRED FIRST AND WAS GIVEN A 270 DEG TURN WHILE WE WERE IN POS. I BELIEVE THE TWR CTLR ON 36L WAS WATCHING ON ENRTE SPACING, GOT THE SPACING AND CLRED US FOR TKOF, FORGETTING ABOUT THE OTHER ACFT OR NOT KNOWING ABOUT HIM. BETTER COORD BTWN LCL CTLR MIGHT HAVE NOT LET THIS HAPPEN.
