CPR LTT CREW PASSED A NEW HOLD LINE ON TXWY E. NONSTANDARD RWY HOLD SIGN INSTALLED.

Narrative

WE HAD ARRIVED AT THE ARPT A FEW HRS EARLIER UTILIZING A DIFFERENT RWY FROM THAT IN USE AS WE BEGAN OUR TAXI FOR DEP. THE ARPT WAS UNFAMILIAR TO USE BUT NOT OVERLY COMPLEX IN TERMS OF ITS LAYOUT WITH 2 PERPENDICULAR RWYS AND ADJACENT PARALLEL TXWYS. WE WERE TOLD TO FOLLOW ANOTHER CORPORATE TURBOPROP AND TAXI TO RWY 6 FOR DEP. THIS ENTAILED UTILIZING A TXWY WHICH INTERCEPTED THE PARALLEL TXWY OF THE DEP RWY FROM A 45 DEG ANGLE. STILL FOLLOWING THE ACFT AHEAD AND APCHING THE INTXN OF THE 45 DEG AND PARALLEL TXWYS WE OBSERVED A SIGN NOTING THE HOLD LINE FOR RWY 6 WAS 100 FT AHEAD. IMMEDIATELY ADJACENT TO THIS SIGN WAS A HOLD LINE WHICH DID NOT SEEM TO BE 100 FT AWAY. WE ASSUMED THIS MUST BE THE HOLD LINE FOR ACFT ENTERING RWY 6 FROM THAT INTXN AND CONTINUED FOLLOWING THE ACFT AHEAD. WE MADE THE 45 DEG TURN ONTO THE PARALLEL TXWY AND EXPECTED TO SEE ANOTHER HOLD LINE AFTER MAKING THE TURN JUST PRIOR TO REACHING THE END OF THE RWY. THIS WAS NOT THE CASE AS THERE WAS ONLY A FADED OR PAINTED- OVER HOLD LINE NEAR THE END OF THE RWY. IT WAS LOCATED IN A POS COMMON TO MOST RWY HOLD LINES BUT WAS APPARENTLY NOT BEING UTILIZED OR MAINTAINED. THE TWR CTLR MADE NO MENTION OF OUR POS AT THE END OF THE TXWY BEING INAPPROPRIATE AS WE AWAITED OUR DEP. WE COMPLETED OUR DEP AHEAD OF APCHING WX WITHOUT INCIDENT AND RETURNED TO OUR HOME BASE. I DO NOT RECALL THE SIGN NOTIFYING PLTS OF THE APCHING HOLD LINE SPECIFYING IT AS AN ILS HOLD LINE. IF IT WAS IN FACT THE HOLD LINE FOR RWY 6; ITS LOCATION PRIOR TO INTERCEPTING THE PARALLEL TXWY IS THE FIRST I'VE ENCOUNTERED AT SUCH A DISTANCE FROM THE RWY. IN RETROSPECT; WE SHOULD HAVE BEEN MORE EXPEDITIOUS IN QUESTIONING THE GND CTLR AS TO THE MEANING OF THE SIGN AND ACTUAL LOCATION OF THE RWY 6 HOLD LINE. IT ALSO SEEMS THAT STANDARD ARPT SIGNAGE SPECIFYING THE LOCATION OF A RWY HOLD LINE IS NORMALLY LOCATED AT THE LINE OR HOLD POS.A SIGN THAT SPECIFIES A HOLD LINE 100 FT AWAY; ESPECIALLY AT AN INTXN; LAYS THE GND WORK FOR CONFUSION IN DETERMINING WHICH IS THE REAL HOLD LINE.
