Narrative:

Final approach to mke runway 7R. At aprox 2 mi final an air carrier Y, B727, had been apparently cleared for takeoff and began to roll. We initiated a go around and proceeded to turn to 090 degrees in order to avoid the takeoff runway and the other aircraft on takeoff roll. We announced go around as tower directed us to go around (we had already commenced the go around before tower told us to), as I turned on the slightly divergent heading and climbed (as directed) toward 3000 ft MSL. Prior to reaching 3000 ft (approximately 2000+ ft) tower directed me to a 340 degree heading. I looked out to my left and slightly down and noticed the B727 climbing parallel to me (very closely). He was probably at 1000+ ft. I told tower that I was not going to turn to the assigned heading as I would then be converging into the path of the B727. He (tower) reiterated the order (as I recall). In any event I refused the order and declared an emergency over the radio. He then directed 090 degrees/3000 ft. I complied. Apparently the 2 airplanes reached safe separation, at which time I received and accepted vectors for another approach. Approach and landing uneventful. Apparently several passenger saw the other aircraft on the go around. I felt it necessary to declare an emergency as I had clear vision of what I reasonably believed would result in possible collision with the other aircraft.

Title: POTENTIAL CONFLICT OCCURS AFTER A SYS ERROR DURING A MISSED APCH BY AN A320 THAT CONFLICTED WITH THE B727 THAT HAD JUST DEPARTED FROM MKE, WI.

Narrative: FINAL APCH TO MKE RWY 7R. AT APROX 2 MI FINAL AN ACR Y, B727, HAD BEEN APPARENTLY CLRED FOR TKOF AND BEGAN TO ROLL. WE INITIATED A GAR AND PROCEEDED TO TURN TO 090 DEGS IN ORDER TO AVOID THE TKOF RWY AND THE OTHER ACFT ON TKOF ROLL. WE ANNOUNCED GO AROUND AS TWR DIRECTED US TO GO AROUND (WE HAD ALREADY COMMENCED THE GAR BEFORE TWR TOLD US TO), AS I TURNED ON THE SLIGHTLY DIVERGENT HEADING AND CLBED (AS DIRECTED) TOWARD 3000 FT MSL. PRIOR TO REACHING 3000 FT (APPROX 2000+ FT) TWR DIRECTED ME TO A 340 DEG HDG. I LOOKED OUT TO MY L AND SLIGHTLY DOWN AND NOTICED THE B727 CLBING PARALLEL TO ME (VERY CLOSELY). HE WAS PROBABLY AT 1000+ FT. I TOLD TWR THAT I WAS NOT GOING TO TURN TO THE ASSIGNED HEADING AS I WOULD THEN BE CONVERGING INTO THE PATH OF THE B727. HE (TWR) REITERATED THE ORDER (AS I RECALL). IN ANY EVENT I REFUSED THE ORDER AND DECLARED AN EMER OVER THE RADIO. HE THEN DIRECTED 090 DEGS/3000 FT. I COMPLIED. APPARENTLY THE 2 AIRPLANES REACHED SAFE SEPARATION, AT WHICH TIME I RECEIVED AND ACCEPTED VECTORS FOR ANOTHER APCH. APCH AND LNDG UNEVENTFUL. APPARENTLY SEVERAL PAX SAW THE OTHER ACFT ON THE GAR. I FELT IT NECESSARY TO DECLARE AN EMER AS I HAD CLR VISION OF WHAT I REASONABLY BELIEVED WOULD RESULT IN POSSIBLE COLLISION WITH THE OTHER ACFT.
