Narrative:
The learjet was level at 9000 ft; overflt west to east; approximately 10 NM west navy sherman (npa). I observed a VFR target in the vicinity (mode C indicated 7000 MSL). After about 2 radar sweeps; the VFR altitude indicated 8800 ft MSL. I issued a traffic alert. The lear advised he had the traffic in sight and was taking evasive action. The lear advised the traffic was a T-34 doing steep climbs. The T-34 was squawking 1200. We at P31 (pensacola TRACON) have an agreement with the training wing at npa to have all aircraft doing aerobatic maneuvers squawk XXXX so we can issue TA's to other aircraft in a timely manner. Since this T-34 didn't do that; it was impossible to issue correct traffic information to the lear. I think they should restrict aerobatic maneuvers to the local MOA's or an area away from the more congested areas of our traffic. 10 mi west of a busy facility is definitely not safe!

Title: P31 CTLR EXPRESSED CONCERN REGARDING CONFLICT BTWN OVERFLT AND VFR MIL ACFT CONDUCTING AEROBATICS CONTRARY TO LOA PROCS.
Narrative: THE LEARJET WAS LEVEL AT 9000 FT; OVERFLT W TO E; APPROX 10 NM W NAVY SHERMAN (NPA). I OBSERVED A VFR TARGET IN THE VICINITY (MODE C INDICATED 7000 MSL). AFTER ABOUT 2 RADAR SWEEPS; THE VFR ALT INDICATED 8800 FT MSL. I ISSUED A TFC ALERT. THE LEAR ADVISED HE HAD THE TFC IN SIGHT AND WAS TAKING EVASIVE ACTION. THE LEAR ADVISED THE TFC WAS A T-34 DOING STEEP CLBS. THE T-34 WAS SQUAWKING 1200. WE AT P31 (PENSACOLA TRACON) HAVE AN AGREEMENT WITH THE TRAINING WING AT NPA TO HAVE ALL ACFT DOING AEROBATIC MANEUVERS SQUAWK XXXX SO WE CAN ISSUE TA'S TO OTHER ACFT IN A TIMELY MANNER. SINCE THIS T-34 DIDN'T DO THAT; IT WAS IMPOSSIBLE TO ISSUE CORRECT TFC INFO TO THE LEAR. I THINK THEY SHOULD RESTRICT AEROBATIC MANEUVERS TO THE LCL MOA'S OR AN AREA AWAY FROM THE MORE CONGESTED AREAS OF OUR TFC. 10 MI W OF A BUSY FACILITY IS DEFINITELY NOT SAFE!
