Narrative:
On an assigned altitude, below a scattered layer, proceeding direct to vld, we received a TA from the tcasi. I looked out for the traffic and spotted it at our altitude and less than 2 mi, moving toward us. I initiated a turn to the right, and passed the other aircraft by approximately 1/2 mi. The controller was questioned about the aircraft, and if he had the other aircraft on radar. He said the aircraft was VFR, being handled by moody AFB approach control. When questioned further about why we were not given a traffic alert by ATC until after the tcasi went off, the captain was instructed to call the watch supervisor at moody approach. We were then cleared for a visual approach to the vld airport. Supplemental information from acn 426927: when I questioned the controller about it, he said that if I had a problem I needed to call his supervisor about it.

Title: AM EMB120 TCASI DETECTS UNKNOWN VFR NORAC OPPOSITE DIRECTION SAME ALT TFC. THE LTT TURNS TO AVOID AN A10 THUNDERBOLT ON MOODY APCH CTL FREQ. ACFT IS 15 MI N OF VLD, FL.
Narrative: ON AN ASSIGNED ALT, BELOW A SCATTERED LAYER, PROCEEDING DIRECT TO VLD, WE RECEIVED A TA FROM THE TCASI. I LOOKED OUT FOR THE TFC AND SPOTTED IT AT OUR ALT AND LESS THAN 2 MI, MOVING TOWARD US. I INITIATED A TURN TO THE R, AND PASSED THE OTHER ACFT BY APPROX 1/2 MI. THE CTLR WAS QUESTIONED ABOUT THE ACFT, AND IF HE HAD THE OTHER ACFT ON RADAR. HE SAID THE ACFT WAS VFR, BEING HANDLED BY MOODY AFB APCH CTL. WHEN QUESTIONED FURTHER ABOUT WHY WE WERE NOT GIVEN A TFC ALERT BY ATC UNTIL AFTER THE TCASI WENT OFF, THE CAPT WAS INSTRUCTED TO CALL THE WATCH SUPVR AT MOODY APCH. WE WERE THEN CLRED FOR A VISUAL APCH TO THE VLD ARPT. SUPPLEMENTAL INFO FROM ACN 426927: WHEN I QUESTIONED THE CTLR ABOUT IT, HE SAID THAT IF I HAD A PROB I NEEDED TO CALL HIS SUPVR ABOUT IT.
