COMPLICATED ARR CHART PLUS INTERFAC COM BREAKDOWN; RPTR CAPT WAS UNSURE OF CLRNC AND APPARENTLY CTLR EXPECTED FLC TO BE AT A SPD WHICH HAD NOT BEEN ASSIGNED NOR DEPICTED ON THE CHART.

Narrative

I WAS THE CAPT OF FLT X FROM BIL TO SLC ON MAR/XX/97. FLT PLAN WAS BIL-JAC-CARTR ONE ARR TO SLC. DURING CRUISE AND N OF JAC WE WERE CLRED DIRECT TO CARTR INTXN BY ZLC AND INSTRUCTED TO FLY THE BAL OF CARTR ONE ARR. A FEW MINS LATER; WE WERE RECLRED TO 'FLY A HEADING AND INTERCEPT THE OGDEN VOR 353 DEG RADIAL AND PROCEED INBOUND TO CARTR INTXN.' AT THIS POINT I FELT WE HAD BEEN REMOVED FROM THE CARTR ONE ARR AND COULD EXPECT VECTORS AT CARTR. WE WERE GIVEN A LATE DSCNT TO CROSS CARTR AT 16000 FT MSL AND 280 KIAS. WE MADE THE XING RESTR AND WERE HANDED OFF TO SLC APCH PASSING CARTR. APCH CLRED US TO INTERCEPT THE ILS TO RWY 16L. I ASKED WHAT HEADING HE WANTED FOR THE INTERCEPT. THE CTLR TOLD US WE SHOULD BE ON THE CARTR ONE ARR WHICH HAS A PUBLISHED INTERCEPT COURSE FOR RWY 16L AND HE ASKED OUR SPD. I TOLD HIM CTR ASSIGNED US 280 KIAS. IT WAS OBVIOUS HE EXPECTED 250 KIAS AS HE SAID WE HAD A 50 PLUS KT OVERTAKE ON THE ACFT IN FRONT OF US. WE SLOWED AND LANDED UNEVENTFULLY ON RWY 16L. THE COM BTWN THE ZLC CTLR AND SLC APCH CTLR SEEMED POOR OR THEY WERE ASSUMING WE WOULD KNOW THEY WANTED US TO SLOW TO 250 KIAS AT THE INTERCEPT AND FLY THE ARR EVEN THOUGH WE HAD BEEN TAKEN OFF THE PUBLISHED ARR EARLIER. NO SPDS ARE PUBLISHED ON THE ARR. IN ADDITION THE CARTR ONE ARR IS CONFUSING AND EASY TO MISINTERPRET (SEE ATTACHED COPY OF CARTR ONE ARR). DIVET INTXN IS THE INTERCEPT POINT FOR THE ILS RWY 16L USING ILS FREQ 109.5; ANOTHER INTXN BAGGG IS 5 MI PAST DIVET AND USES THE ILS RWY 16R FREQ 111.9. THE 2 DIFFERENT FREQS ARE PLACED NEXT TO EACH OTHER ON A VERY CROWDED CHART. I INADVERTENTLY SELECTED 111.9 FOR THE INTERCEPT. WE WERE ALSO CLRED TO CROSS WUDDS INTXN AT OR ABOVE 12000 FT MSL. WUDDS IS NOT ON THE ARR CHART; EVEN THOUGH IT'S 2.1 MI PAST DIVET; OR 32.9 NM FROM SLC. REF IS MADE TO WUDDS ON THE APCH CHART FOR RWY 16L (SEE COPY OF RWY 16L ILS CHART); IT IS NOT DEPICTED ON THE CHART. A NOTE IN SMALL PRINT GIVES THE DME FOR WUDDS. THE CARTR ONE ARR DOES SHOW YYIPP WHICH IS THE FAF AND 7 DME FROM SLC AND NOT NEEDED FOR THE ARR. WUDDS IS BTWN DIVET AND YYIPP ON THE ILS RWY 16L CTRLINE. ALL OF THE SLC ARRS ARE VERY COMPLICATED AND EASY TO MISINTERPRET. THE POTENTIAL FOR ERROR IS HIGH.
