MLG TAKES WRONG TXWY LEAVING RAMP.

Narrative

BEGINNING THE THIRD LEG OF A DUTY DAY THAT APCHED 11 HRS; AFTER 2 LEGS OF HVY TSTM DEVS BEGAN FINAL LEG TO DOMICILE. EXITING PIT RAMP RECEIVED TAXI CLRNC TO RWY 28L. AFTER A QUICK LOOK AT THE TAXI DIAGRAM; AND A RATHER LENGTHY DISCUSSION WITH THE FO WHO WAS CLOSELY CHKING THE DIAGRAM; WE DECIDED WE UNDERSTOOD THE CLRNC AND BEGAN TAXIING. AFTER MOVING APPROX 150 YARDS WE WERE INFORMED THAT WE HAD MADE THE WRONG APCH TO THE DESIRED TXWY -- NO CONFLICT OCCURRED. THE CTLR EMPHASIZED THAT WE SHOULD QUESTION THE CLRNC IF CLARIFICATION IS NEEDED; WHICH IS EXACTLY THE POINT -- 2 EXPERIENCED PLTS. ONE WITH THE CHART TO THEIR NOSE AND A DISCUSSION WITH EACH OTHER AND WHAT WAS CONSIDERED A GOOD DECISION. SOMETHING IS DRASTICALLY WRONG! 1) THE SIGNAGE AT PIT IS MORE THAN INADEQUATE. IN MANY CASES IT IS NONEXISTENT. 2) THE TXWY CHART; BECAUSE OF THE SIZE LIMITATIONS OF 1 SMALL SHEET RATHER THAN THE MULTI-FOLD VERSION IS LACKING IN ADEQUATE DETAIL. 3) THE CTLRS APPARENTLY ASSUME ANYONE USING THEIR FACILITY HAS THE DEGREE OF LCL KNOWLEDGE THEY POSSESS. THIS RPTR FEELS COMPELLED TO SAY THAT PIT IS THE NEXT PERFECT PLACE FOR AN ACCIDENT/INCIDENT LIKE DTW EXPERIENCED WITH THE DC9-727 TAXI/TKOF COLLISION. SOMETHING NEEDS TO BE DONE ABOUT PIT. THE LACK OF ADEQUATE SIGNS; INFO; AND VERBAL COM ARE AS BAD AS ANY PLACE IN THE UNITED STATES. SHOULD IT HAPPEN; IT WOULD HAVE BEEN RATHER EASY TO PREVENT; OTHER FACILITIES DO A FAR BETTER JOB.
