FLC OF ACR MLG ACFT INADVERTENTLY DEVIATED FROM ASSIGNED COURSE DUE TO A COM MISUNDERSTANDING WITH ATC CLRNC DELIVERY.

Narrative

I CALLED RIC CLRNC DELIVERY TO OBTAIN OUR CLRNC FOR FLT RIC TO PHL. OUR RELEASE SHOWED RIC V16 CANNY DQO 195 DQO PHL. HOWEVER; RIC CLRNC GAVE US 'FLY THE RIC 074 DEG RADIAL TO MODEL; INTERCEPT V33; MAINTAIN 3000 FT; EXPECT 19000 FT; DEP 126.4; SQUAWK XXXX.' WE CALLED CLRNC BACK TWICE TO VERIFY THE REMAINDER OF THE ROUTING AND WERE EXPLICITLY TOLD DQO 195 DEG RADIAL; DQO; PHL. LATER IN THE FLT I REQUESTED DIRECT PXT AND WAS TOLD UNABLE. WE ALSO ASKED CTR TO VERIFY THE ROUTING AS IT HAD ALREADY BEEN A TOPIC OF CONVERSATION BTWN THE CAPT AND I; AND WE HAD ALREADY BEEN GIVEN A COUPLE OF VECTORS. WE WERE TOLD V33 CANNY; DQO 195 DEG RADIAL; DQO; PHL. LATER; WE WERE GIVEN A VECTOR TO INTERCEPT THE AIRWAY. I ASSUMED THIS MEANT V16 TO PXT SO I DIALED IN THE PXT 238 DETAIL RADIAL INBOUND (I.E.; V16). EVIDENTLY; THE CTLR MEANT V33 AS HE CALLED LATER TO TELL US WE WERE APCHING A RESTR AREA WHICH MUST HAVE BEEN EITHER R4005 OR R4006. HAD I KNOWN WE WERE TO INTERCEPT V33 INSTEAD OF V16 WE WOULD HAVE HAD THE HCM 010 DEG RADIAL DIALED IN AND REALIZED WE WERE E ON V33. MY CONCERN WITH SITUATIONAL AWARENESS WAS THAT WE INTERCEPT V16 FROM THE S. A COUPLE OF FACTORS AFFECTED WHAT WAS OBVIOUSLY A LACK OF COM BY ALL CONCERNED. IT IS POSSIBLE THAT WE MISSED A CALL FROM CTR AS WE WERE EXPERIENCING A BLEED-OVER ON THEIR FREQ AND COMMENTED TO THEM AS SUCH. HOWEVER; I THINK THE MAIN FACTOR WAS RICHMOND CLRNC FAILING TO READ THE COMPLETE CLRNC; ESPECIALLY SINCE IT WAS DIFFERENT FROM THE ORIGINAL RELEASE.
