Narrative:
During arrival to mfd from fwa, approximately XA30 on aug/xa/99, received an RA climb advisory on TCASII. While being vectored by mansfield approach control, approximately 270 degree radial at 11 DME, 3000 ft MSL, heading 050 degrees (assigned), for traffic on runway 14 approach to galion, mansfield approach control advises of traffic 11 O'clock, 3 mi. We state 'traffic is on TCASII, however, the traffic was not in sight. Approximately 20-30 seconds later, we received a 3000 FPM TCASII RA (climb). We utilized maximum power to obtain RA climb rate and once clear of conflict at 3450 ft MSL, returned to IFR assigned altitude 3000 ft MSL. Mfd approach control is advised that the traffic caused a TCASII RA climb. Mfd approach control states 'what's that?' we describe what an RA is. Mfd approach control states the conflict was 'VFR anyhow.' we missed the traffic by 100 ft vertically. We were then cleared for the visual and full stopped.

Title: FLC OF A MIL C130 TAKE EVASIVE ACTION BY CLBING IN RESPONSE TO A TCASII RA AFTER APCH CTLR ISSUES TA.
Narrative: DURING ARR TO MFD FROM FWA, APPROX XA30 ON AUG/XA/99, RECEIVED AN RA CLB ADVISORY ON TCASII. WHILE BEING VECTORED BY MANSFIELD APCH CTL, APPROX 270 DEG RADIAL AT 11 DME, 3000 FT MSL, HDG 050 DEGS (ASSIGNED), FOR TFC ON RWY 14 APCH TO GALION, MANSFIELD APCH CTL ADVISES OF TFC 11 O'CLOCK, 3 MI. WE STATE 'TFC IS ON TCASII, HOWEVER, THE TFC WAS NOT IN SIGHT. APPROX 20-30 SECONDS LATER, WE RECEIVED A 3000 FPM TCASII RA (CLB). WE UTILIZED MAX PWR TO OBTAIN RA CLB RATE AND ONCE CLR OF CONFLICT AT 3450 FT MSL, RETURNED TO IFR ASSIGNED ALT 3000 FT MSL. MFD APCH CTL IS ADVISED THAT THE TFC CAUSED A TCASII RA CLB. MFD APCH CTL STATES 'WHAT'S THAT?' WE DESCRIBE WHAT AN RA IS. MFD APCH CTL STATES THE CONFLICT WAS 'VFR ANYHOW.' WE MISSED THE TFC BY 100 FT VERTLY. WE WERE THEN CLRED FOR THE VISUAL AND FULL STOPPED.
