Narrative:
We were inbound to pensacola. Descending from 9000 to 6000, heading 270, pns approach called traffic at 12 O'clock at 10 mi at an altitude of 7000. Approach turned us to a heading of 240 to avoid the called traffic. As we turned through 250, TCASII alerted us to new (pop-up) traffic at 12 O'clock, 2 mi, at our altitude. Due to haze, we were unable to see the new traffic, and we were unable to get a hold of approach due to radio traffic. TCASII gave a RA indicated by a red band on the vsi from 4000 FPM climb to 3000 FPM descent. We climbed to 8300 ft before the TCASII gave the all clear. There was no green band indicated. We advised ATC, he replied he did not see the traffic. We landed at pns.

Title: MLG FLC DSNDING TO PNS, GIVEN TFC AND TURN, IN TURN TCASII RA DICTATED A CLB TO CLR RA.
Narrative: WE WERE INBOUND TO PENSACOLA. DSNDING FROM 9000 TO 6000, HDG 270, PNS APCH CALLED TFC AT 12 O'CLOCK AT 10 MI AT AN ALT OF 7000. APCH TURNED US TO A HDG OF 240 TO AVOID THE CALLED TFC. AS WE TURNED THROUGH 250, TCASII ALERTED US TO NEW (POP-UP) TFC AT 12 O'CLOCK, 2 MI, AT OUR ALT. DUE TO HAZE, WE WERE UNABLE TO SEE THE NEW TFC, AND WE WERE UNABLE TO GET A HOLD OF APCH DUE TO RADIO TFC. TCASII GAVE A RA INDICATED BY A RED BAND ON THE VSI FROM 4000 FPM CLB TO 3000 FPM DSCNT. WE CLBED TO 8300 FT BEFORE THE TCASII GAVE THE ALL CLR. THERE WAS NO GREEN BAND INDICATED. WE ADVISED ATC, HE REPLIED HE DID NOT SEE THE TFC. WE LANDED AT PNS.
