VECTORED FOR ILS APCH; FLC STARTED TURN IN BEFORE CLRED TO INTERCEPT. CTLR INTERVENED; ASSIGNED A NEW HDG AND CLRED THEM FOR THE APCH.

Narrative

END OF LONG DAY. BEEN FLYING IN CAVU. LAST APCH OF DAY. COMING INTO HOME BASE. I WAS VERY RELAXED AND COMPLACENT. WE SET UP FOR ILS 2C AND WERE ON VECTORS FOR INTERCEPT. THE L SIDE GS IS NOT VISIBLE FROM CAPT SIDE. I HAD TUNED #2 NAV TO ILS SO I WOULD HAVE GS BACK-UP. PF ASKED ME TO CHANGE IT BACK TO BNA VOR SO HE WOULD HAVE DME FOR GS STEP-DOWNS. I HAD JUST RESET #2 TO VOR WHEN THE LOC NEEDLE STARTED TO COME IN. THE AUTOPLT BEGAN TO TRACK IT (WE HAD AN ASSIGNED HDG OF 270 DEGS). PF AND I WERE BOTH WATCHING. APCH CTL ASKED US WHAT WE WERE DOING AS WE WERE PASSING HDG 330 DEGS. THE PF AND I BOTH REALIZED WE HAD NOT BEEN CLRED FOR THE APCH OR CLRED FOR INTERCEPT. THE CTLR THEN GAVE US HDG OF 260 DEGS TO REPOS. WE WERE THEN CLRED TO INTERCEPT THEN CLRED FOR APCH; WHICH WAS SUCCESSFUL AND WITHOUT FURTHER INCIDENT. 1) I WAS WAY TOO COMPLACENT AND NOT KEEPING TRACK OF POS CLRNCS. 2) I WAS DISTR BY THE PF'S REQUEST TO RETUNE #2 NAV. 3) WE WERE BOTH AWARE OF FALSE LOC INDICATIONS BUT DID NOT QUESTION THE NEEDLE MOVEMENT AND SINCE IT HAS HAPPENED BEFORE; I ASSUMED THE CTLR HAD FORGOTTEN TO TURN US ON TIME. NO EXCUSE FOR PNF TO BE SO LAX IN RADIO MONITOR PF RESPONSIBILITIES. WHEN I CHANGED #2 NAV; I DID NOT ADVISE THE PF OF WHAT I WAS DOING. BEFORE CHANGING THE #2 NAV TO ILS; I SHOULD HAVE ENGAGED THE DME HOLD FEATURE; SO WE COULD BOTH HAVE DISTANCE MEASUREMENTS FROM THE RWY. I WOULD BE HAPPIER IF L SIDE GS INFO WAS VISIBLE FROM THE R SEAT.
