UNDER TWR LCL CTL AN ACR IS HELD SHORT OF THE PARALLEL TXWY ON THE RWY SIDE OF THE RWY HOLD SHORT LINE. ANOTHER ACFT IS HOLDING IN POSITION FOR TAKE OFF. PREVIOUS EXPERIENCE WITH ACFT BEING CLRED FOR TAKE OFF IN SIMILAR SITS CAUSES THE RPTR TO QUESTION TWR'S INTENTION.

Narrative

THIS IN MY SECOND INSTANCE OF THIS OCCURRENCE AND MY SECOND NASA RPT ON THIS SUBJECT. LANDED RWY 18R CVG AND TOLD BY LCL TO EXIT AT D7 AND HOLD SHORT OF D AT D7. ACFT Y; AN MD88 MOVING N ON D WAS TO MY R. TWR CLRED AN ACR ABC (ACFT Z) (WE WERE ACR ABD (ACFT X) INTO POS AND HOLD. I TOLD TWR THAT HOLDING SHORT OF D ON D7 WOULD KEEP ME ON RWY 18R SURFACE BY LOCATION OF HOLD SHORT MARKINGS AND BY DEFINITION OF THOSE MARKINGS. HE TOLD ME TO HOLD SHORT OF D AND I REPEATED MY OBJECTION. IT WAS OBVIOUS HIS INTENTION WAS TO LAUNCH ACR ABC (ACFT Z) WHICH WOULD HAVE RESULTED IN A LOSS OF SEPARATION WITH US SINCE WE WERE ON RWY 18R SIDE OF THE HOLD SHORT LINES. HE FINALLY ASKED ACR ABC (ACFT Z) WHAT HIS POSITION WAS AND ACFT Z ANSWERED HOLDING IN POSITION. I TOLD THE TWR ON THE RADIO THAT I HAD ALREADY SUBMITTED ONE NASA RPT FOR THIS. TWR THEN TOLD ACFT Z TO HOLD IN POSITION. THIS PROBABLY HAPPENS ON A DAILY BASIS. THE FAA FLOODS US WITH RWY INCURSION WARNINGS AND THEN ASKS US TO SIT ON RWY CONCRETE WHILE THEY ACTUALLY INCUR A D AND L BY LAUNCHING AN ACFT WITH ONE HOLDING SHORT OF A TXWY ON THE RWY SIDE. (MY OTHER OCCURRENCE THE TWR ACTUALLY LAUNCHED AN ACFT WITH ME STILL HOLDING SHORT OF D ON THE RWY SIDE). THE ACFT Y; MD88 HAD STOPPED SHORT OF D WAITING TO SEE WHAT WAS GOING TO HAPPEN. WHEN WE DIDN'T MOVE; THE MD88 CONTINUED ITS TAXI. AS IT APPROACHED D7; TWR CLRED US ACROSS D INTO THE RAMP AREA. I ADVISED TWR THAT WE WOULD HOLD FOR THE MD88 TO CLR BEFORE CROSSING TXWY D. HAD AN INTERESTING CONVERSATION WITH TWR SUPVR AFTER PARKING. THIS MUST STOP! ACFT HOLDING SHORT OF D ON D7 FOR CROSSING TFC ON D ARE NOT PROTECTED FROM ACFT TAKING OFF ON RWY 18R AT CVG. SOONER OR LATER THERE WILL BE AN ACCIDENT AND IT WILL BE FAA'S FAULT! CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: CALLBACK REVEALED THAT THE RWY HOLD SHORT LINE IS ABOUT TEN FT FROM THE PARALLEL TXWY. TO HOLD SHORT OF THE TXWY AFTER LNDG THERE IS NO WAY FOR THE HOLDING ACFT TO BE OUT OF THE RWY ENVIRONMENT AS DEFINED BY THE HOLD SHORT LINE.
