Narrative:

Reno, nv, sunday afternoon, week of reno air races, landing during large specific type small aircraft fly-in in progress (mixing VFR light airplanes with IFR air carrier). Landing north localizer back course runway 34L rno. On long base leg south of airport 20 NM, heading 270 degrees, we had to turn to heading of 300 degrees to avoid potential high terrain to west. Approach control frequency was jammed with chatter. Advised controller later. At 9000 ft, 9 NM south, received an RA on our TCASII while tracking the back course localizer runway 34L. Leveled at 9000 ft and acquired the small aircraft visually, also turned left. Recommend: better coordination between approach control and organizer of the small aircraft fly-in. Mixing this much VFR traffic with IFR air carrier is not a comfortable situation.

Title: MLG HAS TCASII RA, LEVELED AND TURNED AS SIGHTED VISUALLY.

Narrative: RENO, NV, SUNDAY AFTERNOON, WK OF RENO AIR RACES, LNDG DURING LARGE SPECIFIC TYPE SMA FLY-IN IN PROGRESS (MIXING VFR LIGHT AIRPLANES WITH IFR ACR). LNDG N LOC BACK COURSE RWY 34L RNO. ON LONG BASE LEG S OF ARPT 20 NM, HDG 270 DEGS, WE HAD TO TURN TO HDG OF 300 DEGS TO AVOID POTENTIAL HIGH TERRAIN TO W. APCH CTL FREQ WAS JAMMED WITH CHATTER. ADVISED CTLR LATER. AT 9000 FT, 9 NM S, RECEIVED AN RA ON OUR TCASII WHILE TRACKING THE BACK COURSE LOC RWY 34L. LEVELED AT 9000 FT AND ACQUIRED THE SMA VISUALLY, ALSO TURNED L. RECOMMEND: BETTER COORD BTWN APCH CTL AND ORGANIZER OF THE SMA FLY-IN. MIXING THIS MUCH VFR TFC WITH IFR ACR IS NOT A COMFORTABLE SIT.
