C560 CREW SELECTED IMPROPER FIRST FIX IN FMC.

Narrative

CONDITIONS WERE CAVU WHEN WE TOOK OFF FROM AN UNCTLED ARPT (GREENVILLE; NC); AFTER HAVING RECEIVED AN IFR CLRNC VIA LCL FSS FREQ. I WAS THE CAPT; BUT THE PNF ON THIS LEG. AS I LOADED BAGS AND BOARDED AND BRIEFED THE PAX; THE PF OBTAINED THE CLRNC THROUGH FLT SVC; AND AS I ENTERED THE COCKPIT; HE WAS FINISHING ENTERING THE RTE INTO THE FMS. AS I GLANCED AT THE FMS SCREEN I SAW RDU AS OUR FIRST WAYPOINT; AND AS THAT WAS A COMMON FIRST WAYPOINT FOR US LEAVING THIS ARPT; I DID NOT QUESTION IT. IN RETROSPECT; THIS IS WHERE WE HAD A BREAKDOWN IN COM; BECAUSE ALTHOUGH WE DID DISCUSS INITIAL ALT AND SQUAWK CODE; I DID NOT ASK ABOUT THE RTE; NOR DID PF VOLUNTEER IT. THIS TRIP IS ONE WE FLY QUITE OFTEN AND ARE THEREFORE VERY FAMILIAR WITH THE GENERAL RTE; SO THERE WAS PROBABLY A FAIR AMOUNT OF COMPLACENCY. ALSO WORTH NOTING IS THE FACT THAT WE NORMALLY -- UNDER GOOD VFR CONDITIONS -- DEPART THIS ARPT VFR AND OBTAIN THE CLRNC IN THE AIR FROM CTR; SO GETTING THE CLRNC ON THE GND THROUGH FSS WAS SOMEWHAT OF A DEP FROM THE NORM FOR US. RWY 1 HAD BEEN USED BY MOST AIRPLANES THAT AFTERNOON. THE WIND HAD GENERALLY BEEN OUT OF THE NNW. AS PF HAD CALLED FOR THE CLRNC; HE HAD GIVEN RWY 1 AS THE INTENDED RWY OF DEP; AND RECEIVED THE FOLLOWING INITIAL ROUTING: 'DIRECT ALWOOD; DIRECT RDU.' ALWOOD IS AN NDB APPROX 3 MI OFF THE DEP END OF RWY 1; STRAIGHT OUT. AS I INDICATED EARLIER; I WAS NOT AWARE OF ALWOOD BEING OUR FIRST FIX IN THE CLRNC. THE THING THAT COMPLICATED MATTERS; AND MORE OR LESS CAUSED OUR PREDICAMENT; WAS THAT BY THE TIME WE TAXIED OUT; THE WIND HAD CHANGED CONSIDERABLY; AND WAS NOW BLOWING FROM DUE W AT 12-14 KTS; CLRLY FAVORING RWY 25. SINCE THE WX WAS GOOD VFR AND NO AIRPLANES WERE SHOWING ON OUR TCASII WITHIN 40 MI; WE DID NOT SEE A PROB WITH SWITCHING RWYS AND USING RWY 25. WE ACTUALLY THOUGHT IT WAS PRUDENT FROM A SAFETY STANDPOINT AS WE WERE AT NEAR GROSS WT FOR TKOF. WE TOOK OFF ON RWY 25; WHICH WAS CLOSE TO IN LINE WITH OUR DIRECTION OF FLT; AND PROCEEDED WESTWARD TOWARDS RDU. AGAIN; I WAS NOT AWARE OF ALWOOD BEING IN THE PICTURE; AND BY NOW; BECAUSE OF THE DISTR FROM THE RWY CHANGE; AND MAYBE BECAUSE THIS FELT JUST LIKE A VFR DEP; IT HAD COMPLETELY SLIPPED MY PARTNER'S MIND. I CONTACTED ZDC ASAP (ROUGHLY 2000 FT) AND THE CTLR QUESTIONED OUR LOCATION AND MENTIONED SOMETHING ABOUT ALWOOD; WHICH CONFUSED ME SINCE I WAS UNAWARE OF ALWOOD BEING IN OUR CLRNC. WE HAD A COUPLE MORE EXCHANGES WHERE HE QUESTIONED WHETHER WE HAD GONE OVER ALWOOD; AND FOR SOME UNEXPLAINABLE REASON; PROBABLY BECAUSE OF ALL THE CONFUSION; AT THAT MOMENT I WAS THINKING THAT ALWOOD NDB WAS ON THE FIELD AT GREENVILLE AND GAVE HIM AN ANSWER SOMETHING TO THE EFFECT OF: 'WELL; WE'VE BEEN THERE; BUT WE'RE HDG W NOW TOWARDS RALEIGH.' AFTER THAT; THE CTLR GAVE US ANOTHER SQUAWK CODE; A HIGHER ALT AND CLRED US DIRECT RDU. THAT WAS THE END OF THAT AS FAR AS WE KNOW.
