ACFT CLEARED INTO POSITION AND HOLD RWY 27L. LNDG ACFT FORCED TO GO AROUND ACCOUNT DELAYED DEP.

Narrative

DEPARTED GATE AT PHL AND CLRED BY GND CTL TO RWY 27L. AFTER XING RWY 27R (WHICH WAS CLOSED); THE COPLT CONTACTED LCL CTL AND WAS TOLD WE WOULD FOLLOW AN MDT WHICH WAS ALREADY CLOSE TO THE RWY. I PARKED MY ACFT OFF TO THE RIGHT TO ALLOW PASSAGE TO THE RWY AND WAITED. RWY 27L WAS BEING USED FOR TKOF AND LNDG AND 1 OR 2 ACFT LANDED BEFORE THE MLG TOOK OFF. THEN 1 OR 2 MORE LNDGS ON 27L (RWY 17 WAS BEING USED FOR SMALLER ACFT). THEN LCL CLRED A WDB INTO POS ON RWY 27L. IT HAD BEEN WAITING ON THE TXWY PARALLEL TO AND E OF THE APCH END OF RWY 27L AFTER THE WDB DEPARTED THERE WAS ANOTHER LNDG; AND I INSTRUCTED THE COPLT TO INQUIRE WHAT OUR DEP SEQUENCE NOW WAS. LCL CTL REPLIED; 'TAXI INTO POS 27L AND HOLD.' THE COPLT ACKNOWLEDGED 'POS AND HOLD; 27L.' I MOVED INTO POS AND SET THE PARKING BRAKE. AFTER AN UNUSUALLY LONG TIME; APPROX 1 MIN; THE LCL CTLR CALLED USING ONLY OUR IDENT. I RESPONDED. LCL SAID; 'I CLRED YOU INTO POS ON RWY 17; YOU ARE IN POS ON RWY 27L.' I SAID; 'NEGATIVE! YOU CLRED ME INTO POS ON 27L AND THAT IS WHAT WAS READ BACK TO YOU.' HE RESPONDED; 'HOLD YOUR POS.' ANOTHER ACFT THEN SAID; 'I'M GOING AROUND.' SUBSEQUENTLY; AN ACFT PASSED SEVERAL HUNDRED FT OVERHEAD; WBOUND. I THEN CALLED LCL CTL; 'TWR; THIS IS ; I WAS CLRED TO 27L BY GND CTL. I WAS IN POS TO TAKE THE RWY WHEN WE INQUIRED OF OUR SEQUENCE. YOU CLRED ME INTO POS; 27L.' HIS REPLY WAS; ' CLRED FOR TKOF.' WE DEPARTED. DUE TO THE GEOGRAPHICAL LAYOUT OF THE ARPT; AFTER TAXIING TO RWY 27L IT WOULD HAVE BEEN IMPOSSIBLE TO TAXI INTO POS ON RWY 17 AS THE APCH END OF 17 IS OVER 1 SM TO THE NW OF 27L. THE WIND WAS 220 DEGS/9 KTS AND TEMP 65 DEGS F ON THE XA03Z PHL WX SEQUENCE. THE MAX TKOF GROSS WT FOR RWY 17 WAS 84000 LBS. WE HAD A TKOF GROSS WT OF OVER 90000 LBS; SO I WOULD HAVE REFUSED A TAXI CLRNC FOR 17. IN OVER 18 YRS OF FLYING THIS ACFT; OUT OF AND INTO PHL; I HAVE NEVER USED RWY 17 FOR TKOF. SUPPLEMENTAL INFO FROM ACN 84691: AT THE TIME OF THIS CONFLICT; PHL ARPT WAS DOWN TO A 2 RWY OPERATION; RWYS 17L AND 27L. NOTAMS SAID RWY 27R WAS CLOSED; BUT GND CTL INFORMED ANOTHER ACFT THAT IT COULD BE USED FOR DEPS.
