MISINTERPRETING THE TERMINAL 'C' INDICATION ON THE COMMERCIAL ARPT CHART FOR THE 'C' TXWY INDICATION RESULTS IN HOLDING AT THE INCORRECT POSITION DURING LOW VIS CONDITIONS AT BOSTON.

Narrative

PLEASE REFER TO COMMERCIAL CHART BOSTON LOGAN. LANDED ON RWY 4R AT BOSTON. TOOK ROMEO TXWY OFF THE RWY TO NOVEMBER-CLRED ACROSS 4L/22R TAXI DOWN NOV TO CROSS 15R/33L THEN LEFT ON KILO AND HOLD SHORT OF CHARLIE. THE VIS WAS POOR. ABOUT 1200 RVR. SOME PLACES BETTER BUT I COULD NOT SEE THE TWR AT ANY TIME. ANYWAY I FOLLOWED THE DIRECTIONS CAREFULLY ESPECIALLY WITH THE LOW VIS AND INFREQUENT VISITS TO BOS. AT WHAT WE THOUGHT WAS CHARLIE ON THE CHART WE STOPPED AS DIRECTED. WAITED A FEW MINS THEN ASKED IF WE COULD CONTINUE. GND ACKNOWLEDGED WITH TAXI TO THE GATE. AT WHAT I THOUGHT WAS CHARLIE ON THE CHART; WE CAME UPON A ACR JET THAT HAD PUSHED BACK. IT TURNS OUT THAT WHAT I WAS LOOKING AT ON THE COMMERCIAL CHART; WAS NOT TXWY CHARLIE BUT THE LETTER C AFTER THE WORD TERMINAL C. THE C IS ACTUALLY PRINTED ON TOP OF A TXWY INTXN. NO PROBS RESULTED. THE ACR JET TAXIED S ON AND THEN DOUBLED BACK AND WE WENT TO THE GATE. I COULD NOT SEE MORE THAN A COUPLE HUNDRED FT AND COULD DEFINITELY NOT SEE THE ACTUAL TXWY CHARLIE THAT IS MUCH FURTHER DOWN. MY EYES LOCKED IN ON THE FIRST C I CAME TO AND STOPPED AND SINCE THE TWR COULD NOT SEE US THEY DID NOT REALIZE I HAD STOPPED SHORT OF THE CORRECT TXWY. RECOMMENDATION. PLEASE HAVE COMMERCIAL CHART REPRINT THE PAGE AND PLACE THE LETTER C IN ANOTHER SPOT WHEN THEY ARE ADDRESSING TERMINALS. AS THEY DID WITH TERMINAL B.
