Narrative:

First officer PF. I am PNF. Monitoring climb as normal, route appears normal, then I realize we are established on wrong airway. We should be on 130 degree radial balance, instead are established on 101 degree radial balance. I question first officer, he responds that my (captain's) EFIS and navigation are set up on the 101 degree radial, so he just assumed it was the correct radial and airway. I explained that the 101 degree radial was from the last leg of mrb, V44 101 degree radial. I had not yet set up an advanced course. I asked if he had not received an amended route since we are often cleared to eno from over balance as a short cut. He responded no, just set his navigation to mine. I explained, he better know where he is going and cleared, which he acknowledged agreeable to be correct. ATC made no issue of this error, probably thinking a previous controller issued this clearance. No other traffic involved. ATC shortly thereafter cleared us this short cut to eno. A lesson to the first officer, but more of a lesson to me, can't drop the guard an instant -- constant vigilance -- no assumptions. 'A good way to fly into a mountain.'

Title: ACR FLC DO NOT CORRECT PIC EFIS NAV GAUGE WITH WRONG HDG AND FO DOES NOT CHALLENGE INPUT INDICATION, CHANGES HIS AND FLT TRACKS INCORRECT NAVAID RADIAL. ERROR IDENTED BY PIC AND ACFT QUICKLY RETURNS TO CORRECT DEP RADIAL. NO ATC INTERVENTION. PIC QUESTIONS FO AND BOTH ACKNOWLEDGE NECESSITY FOR COMPLETING COCKPIT PROC.

Narrative: FO PF. I AM PNF. MONITORING CLB AS NORMAL, RTE APPEARS NORMAL, THEN I REALIZE WE ARE ESTABLISHED ON WRONG AIRWAY. WE SHOULD BE ON 130 DEG RADIAL BAL, INSTEAD ARE ESTABLISHED ON 101 DEG RADIAL BAL. I QUESTION FO, HE RESPONDS THAT MY (CAPT'S) EFIS AND NAV ARE SET UP ON THE 101 DEG RADIAL, SO HE JUST ASSUMED IT WAS THE CORRECT RADIAL AND AIRWAY. I EXPLAINED THAT THE 101 DEG RADIAL WAS FROM THE LAST LEG OF MRB, V44 101 DEG RADIAL. I HAD NOT YET SET UP AN ADVANCED COURSE. I ASKED IF HE HAD NOT RECEIVED AN AMENDED RTE SINCE WE ARE OFTEN CLRED TO ENO FROM OVER BAL AS A SHORT CUT. HE RESPONDED NO, JUST SET HIS NAV TO MINE. I EXPLAINED, HE BETTER KNOW WHERE HE IS GOING AND CLRED, WHICH HE ACKNOWLEDGED AGREEABLE TO BE CORRECT. ATC MADE NO ISSUE OF THIS ERROR, PROBABLY THINKING A PREVIOUS CTLR ISSUED THIS CLRNC. NO OTHER TFC INVOLVED. ATC SHORTLY THEREAFTER CLRED US THIS SHORT CUT TO ENO. A LESSON TO THE FO, BUT MORE OF A LESSON TO ME, CAN'T DROP THE GUARD AN INSTANT -- CONSTANT VIGILANCE -- NO ASSUMPTIONS. 'A GOOD WAY TO FLY INTO A MOUNTAIN.'
