ACR FLC INTERCEPTS THE WRONG COURSE AFTER JAMMN WHILE PERFORMING THE JAMMN 1 STAR AT SLC. THE RPTR FINDS THE NEW JAMMN 1 APCH CHART CLUTTERED AND CONFUSING. THE FLC AND THE ARTCC RADAR CTLR CORRECTED THE ERROR AT THE SAME TIME.

Narrative

I WAS THE FO ON AN ACR FLT ON FEB/MON/96 FROM DEN TO SLC; THE FILED ROUTING WAS VIA MTU AND THE SPANE 1 ARR. AFTER PASSING MTU WE WERE TURNED S ON A DELAYING VECTOR. THE CAPT AND I WERE DISCUSSING THE ALT RESTRS AND NOTED THAT SPANE HAD AN ALT RESTR WHILE THE REMAINING POINTS HAD 'EXPECT' ALTS. WE FURTHER NOTED A BOX IN THE CTR OF THE PAGE THAT HAS IN QUOTATION MARKS; 'DSND VIA SPANE 1 ARR.' AT THIS POINT WE WERE TURNED ON TO A WESTERLY VECTOR WITH A DSCNT CLRNC AND TOLD TO EXPECT THE JAMMN 1 ARR. AS I MADE THE TURN TO THE NEW HEADING AND STARTED A DSCNT THE CAPT LOADED JAMMN AND CHHIP IN THE ONS. WE WERE THEN CLRED DIRECT TO JAMMN AND THE JAMMN 1 ARR. I TURNED DIRECT TO JAMMN AND COUPLED THE AUTOPLT TO THE ONS. ONCE AGAIN WE RECEIVED A VECTOR TOWARDS THE W AND SHORTLY THEREAFTER ANOTHER CLRNC DIRECT TO JAMMN AND 'VIA' THE ARR. AFTER THE TURN DIRECT WE WERE ON THE DTA 358 DEG RADIAL SO I DISCONTINUED USE OF THE ONS TO NAV. ONCE AGAIN THE CAPT AND I WERE DISCUSSING THE 'DSND VIA' STATEMENT ON THE STAR BECAUSE OUR CLRNC WAS 'VIA' THE JAMMN 1. SHORTLY AFTER PASSING JAMMN WE WERE DISCUSSING THE NEXT ALT AND NOTICED ALL THE POINTS ON OUR PLANNED COURSE WERE FOR LNDG S. I THEN REALIZED THE STAR SPLIT AT JAMMN FOR A N LNDG (SLC WAS LNDG N). I IMMEDIATELY TURNED TO INTERCEPT THE PROPER COURSE TO PARRE AND FFU. WHILE WE WERE IN THE TURN ATC CLRED US DIRECT TO FFU. I AM SURE THE CTLR SAW WE HAD MISSED THE TURN AT JAMMN. I BELIEVE THE JAMMN 1 ARR PAGE IS TOO CROWDED; AND THE SPLIT IN TRACK FOR THE S AND N LNDG SHOULD BE MORE PROMINENTLY DEPICTED; AS ON THE CARTR 1 ARR; IT HAS A HIGHLIGHTED BOX AND ARROWS POINTING DIRECTLY AT THE NEW COURSE REQUIRED AT THE SPLIT. THE LACK OF A NARRATIVE DESCRIPTION ALSO CONTRIBUTED.
