Narrative:
We were taking off on runway 24 as the mlt was over the numbers of runway 36 at 1000' AGL on initial leg. As we lifted off at about the intersection of the two runways, tower cleared the mlt to pitchout to the left. At the same time tower directed us to turn left to 180 degrees and asked the mlt if he had us in sight. The reply was that they did not. Our initial climb is quite steep, and we would be through the mlt altitude in a matter of seconds. Since we couldn't see the mlt and they couldn't see us I judge it was a bad call by tower to turn us toward each other. When we began the takeoff roll we thought the mlt would continue its initial leg until we were out of the way. In an attempt to avoid the mlt, which I could not see but which I counted on staying at 1000' until on downwind leg, I began my turn much lower than normal (normal is 500' AGL), and turned with more bank than I would normally use that close to the ground. We also lowered our pitch to increase speed and decrease climb so we would be farther south, and thus clear of the mlt before we climbed through his altitude. Before we exceeded 1000' the mlt crew called us in sight. I requested the tower phone number, but I didn't call back because I wasn't sure we could keep the call constructive. Callback conversation with reporter revealed the following information. Reporter stated the mlt was making a 360 degree overhead approach. His aircraft had xed runway 36R before the mlt was over the runway threshold on his initial approach at 1000' AGL. Pilot's concern was mostly related to the controller turning both aircraft into another west/O either pilot seeing the aircraft. Controller did not issue any traffic advisory. Reporter stated the two aircraft never came closer than 1000' or it could have been more. He never saw the mlt.

Title: A MLT ACFT CONDUCTING A 360 DEG OVERHEAD APCH CAME CLOSE TO MLG ACFT THAT WAS DEPARTING ON AN INTERSECTING RWY.
Narrative: WE WERE TAKING OFF ON RWY 24 AS THE MLT WAS OVER THE NUMBERS OF RWY 36 AT 1000' AGL ON INITIAL LEG. AS WE LIFTED OFF AT ABOUT THE INTXN OF THE TWO RWYS, TWR CLRED THE MLT TO PITCHOUT TO THE L. AT THE SAME TIME TWR DIRECTED US TO TURN L TO 180 DEGS AND ASKED THE MLT IF HE HAD US IN SIGHT. THE REPLY WAS THAT THEY DID NOT. OUR INITIAL CLB IS QUITE STEEP, AND WE WOULD BE THROUGH THE MLT ALT IN A MATTER OF SECS. SINCE WE COULDN'T SEE THE MLT AND THEY COULDN'T SEE US I JUDGE IT WAS A BAD CALL BY TWR TO TURN US TOWARD EACH OTHER. WHEN WE BEGAN THE TKOF ROLL WE THOUGHT THE MLT WOULD CONTINUE ITS INITIAL LEG UNTIL WE WERE OUT OF THE WAY. IN AN ATTEMPT TO AVOID THE MLT, WHICH I COULD NOT SEE BUT WHICH I COUNTED ON STAYING AT 1000' UNTIL ON DOWNWIND LEG, I BEGAN MY TURN MUCH LOWER THAN NORMAL (NORMAL IS 500' AGL), AND TURNED WITH MORE BANK THAN I WOULD NORMALLY USE THAT CLOSE TO THE GND. WE ALSO LOWERED OUR PITCH TO INCREASE SPD AND DECREASE CLB SO WE WOULD BE FARTHER S, AND THUS CLR OF THE MLT BEFORE WE CLBED THROUGH HIS ALT. BEFORE WE EXCEEDED 1000' THE MLT CREW CALLED US IN SIGHT. I REQUESTED THE TWR PHONE NUMBER, BUT I DIDN'T CALL BACK BECAUSE I WASN'T SURE WE COULD KEEP THE CALL CONSTRUCTIVE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR STATED THE MLT WAS MAKING A 360 DEG OVERHEAD APCH. HIS ACFT HAD XED RWY 36R BEFORE THE MLT WAS OVER THE RWY THRESHOLD ON HIS INITIAL APCH AT 1000' AGL. PLT'S CONCERN WAS MOSTLY RELATED TO THE CTLR TURNING BOTH ACFT INTO ANOTHER W/O EITHER PLT SEEING THE ACFT. CTLR DID NOT ISSUE ANY TFC ADVISORY. RPTR STATED THE TWO ACFT NEVER CAME CLOSER THAN 1000' OR IT COULD HAVE BEEN MORE. HE NEVER SAW THE MLT.
