DC9 FO CONFUSES CHART MILEAGE MARKERS WHILE FLYING THE KORRY ONE STAR AND UNDERSHOOTS XING RESTR. RESTR MISSED AS CHART IS FOLDED; BLOCKING ADDITIONAL NOTATIONS.

Narrative

THIS WAS THE FIRST TIME FLYING THIS STAR. WE WERE TOLD TO DSND VIA THE KORRY ONE ARR. SECOND TO THE LAST XING FIX WAS 'BRAND;' CROSS BRAND AT 11000 FT. LAST XING IS 'KORRY' AT 10000 FT. STAR DISTANCE IS CONFUSING AT KORRY. STAR SHOWS 'BRAND' 15 NM FROM RBV; UNDERNEATH THE 15 MI MARKER IS A '5.' I CONFUSED THIS TO MEAN KORRY DME DISTANCE WAS 5 MI FROM RBV. MY ESTIMATE OF KORRY DME WAS INCORRECT. THE '5' MEANT; 5 MI BTWN BRAND AND KORRY; WHICH PUT KORRY AT 10 DME FROM RBV. I CROSSED 10 DME OUT OF RBV AT 10700 FT. REMAINDER OF FLT WAS UNEVENTFUL. AT THE GATE; I LOOKED AT THE STAR AGAIN AND REALIZED MY ERROR. THE STAR ACTUALLY SHOWS A MORE DETAILED AREA OF THE KORRY INTXN TO THE L OF THE MAIN DEPICTION. I DID NOT SEE THIS EXTRA DEPICTION BECAUSE I HAD MY CHART FOLDED OVER AT THAT EXACT SPOT. THE REASON I HAD MY CHART FOLDED WAS TO AVOID MY CHART FROM INTERFERING WITH THE FLT CTLS. FROM NOW ON; I WILL TRIPLE CHK A NEW CHART/STAR THAT I FLY. I WILL ALSO NOT FOLD OVER MY CHART ANY MORE. I ALSO FEEL THE STAR SHOULD HAVE A BETTER DEPICTION OF THE DISTANCE FROM RBV TO KORRY INTXN.
