ACR CAPT FEELS CODED TAXI CLRNCES AT DFW REQUIRE EXCESSIVE FLT CREW HEADS DOWN TIME WHEN SUBSEQUENT SECONDARY CODED CLRNC IS ISSUED AS THE ACFT PASSES FROM THE EAST TO WEST GND CTLR OR VICE VERSA.

Narrative

DEV FROM TAXI CLRNC: REFERENCE DFW ARPT PAGE AND THE COMPANY TAXI RTE PAGES CLRNC FROM SPOT XX -- 'RWY 36R BRIDGE' APCHING HA ON B WESTBOUND AFTER FREQ CHANGE -- CLRNC ISSUED 'RWY 36R FULL LENGTH.' I SLOWED THE ACFT AS I REFERENCED THE CHART AND THE FO AND I BOTH MISREAD THE RTE TO BE G; A; THEN HS; WR. I REFERENCED THE CHART AGAIN AND CAUGHT THE ERROR AS I PASSED UP HA; STOPPED THE ACFT WELL SHORT OF G AND REQUESTED A 'PLAIN LANGUAGE' TAXI RTE VERIFICATION. WE WERE THEN INSTRUCTED TO CONTINUE TO HOLD SHORT OF G AND FOLLOW OTHER TAXIING ACFT TO RWY 36R VIA WR. NORMAL DEP. AFTER REVIEWING THE TAXI RTE CHART IN CRUISE; I NOTICED A SIGNIFICANT DIFFERENCE IN THE EXIT SPOT BLOCK CONSTRUCTION FOR RWY 18L OUTER; INNER; AND FULL LENGTH AND RWY 36R OUTER; INNER; AND FULL LENGTH. I BELIEVE THE USE OF THE BOLD HORIZONTAL DIVIDER FOR THE RWY 36R FULL LENGTH BLOCK (NOT USED FOR RWY 18L) CAUSED US TO USE THE WRONG RTE.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STRESSED THAT THE USE OF CODED CLRNCES WHILE THE ACFT IS UNDERWAY REQUIRE AT LEAST ONE PLT TO GO HEADS DOWN; RETRIEVE THE CODED TAXI RTE PAGE; READ THE APPROPRIATE VERBIAGE AND THEN RETURN TO THE ARPT PAGE; DETERMINE HOW THAT CODED ROUTING TRANSLATES TO ACFT MOVEMENT AND THEN TRANSMIT THAT INFO TO THE TAXIING PLT TO ENSURE COMPLIANCE. IT IS THE RPTR'S OPINION THAT THE ROUTING BEYOND GND CTL SWITCHOVER POINT WOULD BE MORE USER FRIENDLY IN PLAIN LANGUAGE BECAUSE THE ROUTING SUBSEQUENT TO THE CHANGEOVER IS NEITHER LENGTHY NOR COMPLEX. A PLAIN LANGUAGE CLRNC WOULD ALLOW BOTH PLTS TO RETAIN THE ARPT PAGE FOR REFERENCE; THUS ELIMINATING THE EXTRANEOUS STEPS LISTED ABOVE.
