RWY INCURSION.

Narrative

ACFT WAS BEING UTILIZED FOR A LCL TRAINING FLT OF TOUCH AND GO'S WITH A PRIVATE PLT APPLICANT. I WAS PLT IN COMMAND OF THAT FLT. THE STUDENT CONDUCTED A PREFLT INSPECTION FOLLOWED BY A NORMAL SUPERVISED ENG START. THE STUDENT THEN COPIED THE CURRENT ATIS AND CONTACTED GND CTL FOR TAXI CLRNC IN THE FOLLOWING MANNER: 'PROVIDENCE GND SMA X AT 'LOCATION' WITH CURRENT ATIS CODE TOUCH AND GO'S; TAXI.' GND CTL RESPONDED WITH THE COMMAND: 'TAXI TO RWY 23R.' NO SPECIFIC TAXI RTES OR HOLD SHORT COMMANDS WERE GIVEN. AS DEPICTED IN THE DIAGRAM; I TAXIED UP TO; AND HELD SHORT OF; THE BROAD YELLOW LINE THAT INDICATES THE BEGINNING OF THE DISPLACED THRESHOLD FOR RWY 23R. HOLDING SHORT OF 23R ON TAXIWAY V; THE STUDENT BEGAN THE GND CHK SEQUENCE. AT THIS TIME; GND CTL STATED: 'FOR YOUR INFO THE HOLD SHORT LINES ARE 150 FT TO YOUR REAR.' SINCE I FOLLOWED THE PREVIOUSLY GIVEN TAXI INSTRUCTION; I WAS CONFUSED AND QUERIED GND CTL WITH: 'DID YOU TELL US TO HOLD SHORT.' GND CTL DID NOT RESPOND; AND I CONTINUED TO SUPERVISE THE STUDENT ON THE ASSUMPTION THAT IT WAS NOT AN IMPORTANT MATTER. AFTER CONDUCTING THE GND CHK; WE RECEIVED TKOF CLRNC FOR 23R AND WERE INSTRUCTED TO MAKE R CLOSE TFC. UPON COMPLETION OF THE TRAINING FLT AND RECEIPT OF LNDG CLRNC; I WAS ADVISED TO CONTACT THE ATC SUPVR BY PHONE; WHICH I DID IMMEDIATELY AFTER SECURING THE ACFT. THE SUPVR INFORMED ME A PLTDEV COULD BE FILED BECAUSE OF MY ACTIONS. I WAS SHOCKED; HAVING COMPLIED WITH ALL CLRNCS. AFTER CONFERRING WITH A CTLR IN THE BACKGND WHO WAS OBVIOUSLY ADAMANT ABOUT FILING SUCH A DEV; THE SUPVR SAID: 'WE'VE HAD SOME CONFUSION ABOUT THE MARKINGS IN THAT AREA; AND IT PROBABLY WON'T HURT YOU MUCH; BUT WE'RE GOING TO FILE A DEV TO MAYBE GET SOME ACTION OUT OF THE STATE ABOUT CLRING THAT AREA UP.' THE MARKINGS IN THAT AREA ARE CONFUSING AND FADED AND I HAVE WITNESSED ON SEVERAL OCCASIONS ACFT TO INCLUDE GENERAL AVIATION AND BUSINESS JETS IN VIOLATION OF THOSE PARTICULAR HOLD LINES. ADDITIONALLY; UPON HEARING FAMILIAR TAIL NUMBERS GND CTL WILL SIMPLY SAY TAXI TO RWY 'X' OR TAXI TO PARKING; WITHOUT ISSUING A SPECIFIC RTE CLRNC EVEN THOUGH THERE MAY BE SEVERAL DIFFERENT WAYS TO GET THERE. MANY TIMES; I HAVE BEEN FORCED TO ASK FOR SUCH A CLRNC TO STAY OUT OF TROUBLE. I DID NOT THE DAY IN QUESTION BECAUSE THE RWY WAS CLOSE TO OUR FBO. TO PREVENT FURTHER MISUNDERSTANDINGS AND POSSIBLE SAFETY HAZARDS; I WOULD RECOMMEND THE RWY AND TAXIWAY MARKINGS BE REPAINTED; AND FURTHER LINES ADDED TO MAKE THE AREA IN QUESTION LESS CONFUSING. ADDITIONALLY; GND CTLRS SHOULD ISSUE SPECIFIC RTE CLRNCS TO THE ACTIVE RWY; REGARDLESS OF HOW FAMILIAR WITH THE ARPT THE PLT IS; OR HOW CLOSE TO THE RWY THE ACFT IS.
