Narrative:

On an IFR departure out of topeka billard, ks, I was given a routing of V-77 and 5000' runway heading to join V77. I departed north on runway 35 1 1/2-2 mi north of airport. I started to intercept V77 and started a left turn to heading 240 degree to correctly intercept V77 swbnd. ATC came on radio and asked me my heading, I told them 270 degree turning at the time around to 240 degree to intercept V77 southwest. ATC said I just caused a traffic conflict and they were filing a report. Light transport Y was the other aircraft. I feel I should have been given an altitude lower than light transport Y to prevent a conflict, as light transport Y was departing topeka, ks forbes field north at the same time. The controller said I was to fly heading 350 degree until told to join V77. I don't remember being given this clearance. If I was given this clearance why wasn't I separated by altitude from light transport Y thus preventing the conflict.

Original NASA ASRS Text

Title: LIGHT TWIN ENGINE ACFT DEPARTING TOPEKA EXPERIENCES A LOSS OF SEPARATION.

Narrative: ON AN IFR DEP OUT OF TOPEKA BILLARD, KS, I WAS GIVEN A ROUTING OF V-77 AND 5000' RWY HDG TO JOIN V77. I DEPARTED N ON RWY 35 1 1/2-2 MI N OF ARPT. I STARTED TO INTERCEPT V77 AND STARTED A LEFT TURN TO HDG 240 DEG TO CORRECTLY INTERCEPT V77 SWBND. ATC CAME ON RADIO AND ASKED ME MY HDG, I TOLD THEM 270 DEG TURNING AT THE TIME AROUND TO 240 DEG TO INTERCEPT V77 SW. ATC SAID I JUST CAUSED A TFC CONFLICT AND THEY WERE FILING A REPORT. LTT Y WAS THE OTHER ACFT. I FEEL I SHOULD HAVE BEEN GIVEN AN ALT LOWER THAN LTT Y TO PREVENT A CONFLICT, AS LTT Y WAS DEPARTING TOPEKA, KS FORBES FIELD N AT THE SAME TIME. THE CTLR SAID I WAS TO FLY HDG 350 DEG UNTIL TOLD TO JOIN V77. I DON'T REMEMBER BEING GIVEN THIS CLRNC. IF I WAS GIVEN THIS CLRNC WHY WASN'T I SEPARATED BY ALT FROM LTT Y THUS PREVENTING THE CONFLICT.
