THE PLANNED DEP WAS FLOWN FROM LAS VEGAS; NV; INSTEAD OF THE ONE ASSIGNED WHEN THE CLRNC WAS RECEIVED.

Narrative

DEPARTING OUT OF LAS VEGAS; WE FILED THE VEGAS 1 SID. DURING THE RADIO SET-UP; THE VEGAS 1 WAS ENTERED INTO THE FMS. WE TRIED GETTING OUR CLRNC VIA PDC AND WERE UNABLE. THE PNF PICKED IT UP VIA THE RADIO. WE WERE ISSUED THE ACCES DEP; ACCES TRANSITION. BOTH OF US COMPLETELY MISSED THE 'DEP' PORTION OF THE CLRNC AND FOCUSED ON THE ACCES TRANSITION; WHICH ONE DID APPEAR ON THE VEGAS 1 SID. I HAD BEEN INADVERTENTLY LOOKING AT THE VEGAS 1 DEP STILL. I THOUGHT I HAD THE CORRECT SID; AND SO DID THE OTHER PLT. UPON DEP; I FLEW THE VEGAS 1; WHICH IS RWY HDG; 7000 FT; EXPECT RADAR VECTORS. WE RECEIVED FURTHER CLRNC DURING THE CLB WHILE ON RWY HDG TO 15000 FT. AROUND 13000 FT; ATC ASKED US IF WE HAD THE TFC IN SIGHT. WE RESPONDED YES. ATC THEN ASKED IF WE WERE TURNING OR ON THE SID. OUR RESPONSE WAS 'WE'RE ON RWY HDG.' HE COMMENTED THAT HE NEVER GAVE US THAT; AND TO TURN L DIRECT TO ONE OF THE INTXNS ON THE SID. WE ASKED FOR A HDG UNTIL WE GOT IT SET UP. WE BOTH FULLY REALIZED OUR ERROR AT THIS POINT. WE GUESS THAT WE WERE ABOUT 20 DEGS OFF WHERE THE SID INTXN WAS. THERE WERE NO TFC DEVS OR EVASIVE ACTIONS TAKEN. I THINK A VARIETY OF FACTORS ALLOWED THIS TO HAPPEN. I JUST RECENTLY CHANGED FLYING ENVIRONMENTS AFTER 10 YRS FROM IZI TO CPR. THE FMS IS STILL RELATIVELY NEW TO ME. I WAS COMFORTABLE WITH MY FLYING PARTNER AND HIS FAMILIARIZATION OF THE VEGAS AREA AND DIDN'T QUESTION THE DEP PROC. ALTHOUGH I DID WATCH HIM LOOK AT THE FMS SCREEN WITH A PERPLEXED LOOK; HE DIDN'T VOICE HIS DOUBTS OR QUESTIONS OUT LOUD. TO COMPOUND THE ISSUE; THIS WAS ONLY OUR SECOND LEG TOGETHER. I DIDN'T KNOW HOW TO INTERP WHAT I THOUGHT I SAW ON HIS FACE. I ALSO HAD A NAGGING FEELING AS WE CLBED OUT THAT WE SHOULD QUERY ATC ABOUT OUR HDG; BUT DIDN'T FOLLOW THROUGH. TO PREVENT THIS FROM OCCURRING AGAIN; I WILL CHK AND DOUBLECHK WHAT DEP IS GIVEN. CHKING TO BE SURE THE DEP CLRNC TITLE MATCHES WHAT WE HAVE IN OUR BOX/HAND; NOT JUST THE NAME OF AN INTXN OR TRANSITION. I WILL USE BETTER CRM AS WELL. ASKING; 'WHY THE LOOK ON YOUR FACE?' HAVING A BETTER BRIEF OVER THE SID; AND ASKING IF YOU HAVE ANY QUESTIONS OR DOUBTS ABOUT WHAT AND WHERE WE'RE GOING; CHKING THE FMS TO BE SURE THAT IT AGREES WITH OUR CLRNC; AND IF THERE WAS THE SLIGHTEST DOUBT ABOUT ANYTHING; EITHER CLARIFY WITH CLRNC OR ASK ATC IF IN THE AIR!
