Narrative:
F28 took off ahead of us and was assigned a heading of 260 degrees. We were cleared for takeoff and given a 200 degree heading. Both our initial altitudes were 4000 ft. Shortly after liftoff we heard the F28 being assigned a left turn to 200 degrees. On our tcasi 5 mi scale, a target appeared to be closing on us. I told first officer to start slight left turn and he said he would stop climb. At about 190-180 degrees of heading and 2500 ft altitude, I queried the controller about target. He gave us a heading of 140 degrees. No sighting of target and no warning from tcasi. Supplemental information from acn 347460: our takeoff clearance was turn left to 200 degree heading. After reaching 400 ft AGL, our procedures, I began a standard rate left turn to 200 degrees. Just before turning I heard ATC (pit tower) tell the F28 to turn to 200 degrees. I told my captain as I stopped my climb and turned to the left. He asked ATC (departure) who quickly yelled 140 degree heading.
Original NASA ASRS Text
Title: POTENTIAL CONFLICT SENSED BY BE1900 FO ON HIS TCASI DURING DEP. IN TRAIL SEPARATION LOST WHEN PRECEDING ACFT, AN F28, WAS TURNED INTO PATH OF BE1900. CTLR GAVE F28 THE SAME HDG AS GIVEN BE1900.
Narrative: F28 TOOK OFF AHEAD OF US AND WAS ASSIGNED A HDG OF 260 DEGS. WE WERE CLRED FOR TKOF AND GIVEN A 200 DEG HDG. BOTH OUR INITIAL ALTS WERE 4000 FT. SHORTLY AFTER LIFTOFF WE HEARD THE F28 BEING ASSIGNED A L TURN TO 200 DEGS. ON OUR TCASI 5 MI SCALE, A TARGET APPEARED TO BE CLOSING ON US. I TOLD FO TO START SLIGHT L TURN AND HE SAID HE WOULD STOP CLB. AT ABOUT 190-180 DEGS OF HDG AND 2500 FT ALT, I QUERIED THE CTLR ABOUT TARGET. HE GAVE US A HDG OF 140 DEGS. NO SIGHTING OF TARGET AND NO WARNING FROM TCASI. SUPPLEMENTAL INFO FROM ACN 347460: OUR TKOF CLRNC WAS TURN L TO 200 DEG HDG. AFTER REACHING 400 FT AGL, OUR PROCS, I BEGAN A STANDARD RATE L TURN TO 200 DEGS. JUST BEFORE TURNING I HEARD ATC (PIT TWR) TELL THE F28 TO TURN TO 200 DEGS. I TOLD MY CAPT AS I STOPPED MY CLB AND TURNED TO THE L. HE ASKED ATC (DEP) WHO QUICKLY YELLED 140 DEG HDG.
