RWY INCURSION.

Narrative

AFTER EXITING RWY 27L; FO RECEIVED CLRNC TO TAXI E ON B TO THE B PAD AND HOLD AWAITING GATE ASSIGNMENT. THE FO THEN SELECTED AND MONITORED VHF #2 TO TALK WITH RAMP CTL WHILE CAPT TAXIED TOWARD THE B PAD. AS THE B PAD APCHED; THE FO OBSERVED THE CAPT PASSING THE B PAD AND XING THE APCH END OF RWY 32R. ALTHOUGH THE RWY WAS NOT IN USE; CLRNC HAD NOT BEEN RECEIVED TO CROSS IT. THUS; A RWY INCURSION. CAUSE: THE COMMERCIAL ARPT DIAGRAM IS UNCLR ABOUT THE LOCATION OF THE B PAD. THE LABEL IS LOCATED NEAR AND OLD ALERT PAD WITH AN ARROW TOWARD THE ACTUAL B PAD. I BELIEVE THE CAPT BECAME CONFUSED OR MISUNDERSTOOD THE LOCATION OF THE B PAD AND TAXIED ACROSS RWY 32R TOWARD THE OLD ALERT FACILITY (UNITED STATES AIR FORCE). CORRECTION. TAKE MORE TIME TO ENSURE TAXI RTE IS FOLLOWED AND RECOMMEND COMMERCIAL CHARTS LOCATE THESE LABELS CLOSER TO THE ACTUAL HOLD PAD. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: FO WOULD LIKE TO HAVE BEEN AVAILABLE TO OFFER HELP TO CAPT WHO WAS PERFORMING THE TAXI DUTIES. THE CAPT WAS CLRED TO THE B PAD AND DURING HIS LIMITED TIME ON THE GND HE MISREAD THE ARPT DIAGRAM. ON THE COMMERCIAL PRINTED DIAGRAM THE B PAD IS LOCATED NEXT TO A PAD AREA. WHAT THE TAXIING CAPT DID NOT SEE WAS THE ARROW POINTING TO THE EXACT LOCATION OF THE B PAD. FO FEELS THAT IF THE DESIGNATION B PAD WERE TO BE MOVED ADJACENT OR ON TOP OF THE GEOGRAPHICAL LOCATION OF THE B PAD THERE WOULD BE NO CHANCE FOR MISUNDERSTANDING.
