Narrative:

During arrival to smf we were cleared for the approach, then clearance was canceled, then we were reclred very late and high. This created a very busy cockpit in a short period of time. After handoff to smf tower, the tower controller mentioned that we were diverging right of localizer course. My CDI was centered and on GS. The captain's CDI was full left deflection. No flags, proper frequencys and idents, more confusion until I realized that I had not switched my HSI display source from LNAV to VOR/ILS. I was getting proper GS indication on ADI, but tracking the LNAV course. We went around and completed the next approach normally. In my haste to configure the aircraft for the late approach, I missed flipping the navigation source selector switch. Chain of events: we were initially cleared for the approach while still on the arrival. At that time I manually selected the ILS runway 34L for GS and DME display on my ADI and RMI respectively, while leaving LNAV on my HSI for primary navigation. I did this to increase my situational awareness (specifically for descent planning) intending to xfer the ILS information to the HSI as well when transitioning to the approach. In the ensuing confusion over clrncs and my preoccupation over being high, I neglected to xfer the ILS information to the HSI. There were no flags to alert me to this discrepancy, however, I was flying 'raw data' and if I had been using the flight director, it would not have allowed me to select approach mode, thus alerting me to the confign. Also, the PNF, while having ILS information displayed on his side, was not closely monitoring the approach. I believe he was very busy with the radio and checklists. Finally, this is an airport that we operate to very often, and the field had just gone IFR with 2 1/2 mi of visibility due to drifting smoke. I believe our familiarity with the airport coupled with the 'good IFR' led us to assume, perhaps unconsciously, that this would be a routine and uneventful arrival. Many thanks to the alert controller who broke this chain of events. Many lessons learned.

Title: A B737-300 FLC EXECUTED A MISSED APCH AT SMF AFTER BEING ALERTED TO A LOC DEV.

Narrative: DURING ARR TO SMF WE WERE CLRED FOR THE APCH, THEN CLRNC WAS CANCELED, THEN WE WERE RECLRED VERY LATE AND HIGH. THIS CREATED A VERY BUSY COCKPIT IN A SHORT PERIOD OF TIME. AFTER HDOF TO SMF TWR, THE TWR CTLR MENTIONED THAT WE WERE DIVERGING R OF LOC COURSE. MY CDI WAS CTRED AND ON GS. THE CAPT'S CDI WAS FULL L DEFLECTION. NO FLAGS, PROPER FREQS AND IDENTS, MORE CONFUSION UNTIL I REALIZED THAT I HAD NOT SWITCHED MY HSI DISPLAY SOURCE FROM LNAV TO VOR/ILS. I WAS GETTING PROPER GS INDICATION ON ADI, BUT TRACKING THE LNAV COURSE. WE WENT AROUND AND COMPLETED THE NEXT APCH NORMALLY. IN MY HASTE TO CONFIGURE THE ACFT FOR THE LATE APCH, I MISSED FLIPPING THE NAV SOURCE SELECTOR SWITCH. CHAIN OF EVENTS: WE WERE INITIALLY CLRED FOR THE APCH WHILE STILL ON THE ARR. AT THAT TIME I MANUALLY SELECTED THE ILS RWY 34L FOR GS AND DME DISPLAY ON MY ADI AND RMI RESPECTIVELY, WHILE LEAVING LNAV ON MY HSI FOR PRIMARY NAV. I DID THIS TO INCREASE MY SITUATIONAL AWARENESS (SPECIFICALLY FOR DSCNT PLANNING) INTENDING TO XFER THE ILS INFO TO THE HSI AS WELL WHEN TRANSITIONING TO THE APCH. IN THE ENSUING CONFUSION OVER CLRNCS AND MY PREOCCUPATION OVER BEING HIGH, I NEGLECTED TO XFER THE ILS INFO TO THE HSI. THERE WERE NO FLAGS TO ALERT ME TO THIS DISCREPANCY, HOWEVER, I WAS FLYING 'RAW DATA' AND IF I HAD BEEN USING THE FLT DIRECTOR, IT WOULD NOT HAVE ALLOWED ME TO SELECT APCH MODE, THUS ALERTING ME TO THE CONFIGN. ALSO, THE PNF, WHILE HAVING ILS INFO DISPLAYED ON HIS SIDE, WAS NOT CLOSELY MONITORING THE APCH. I BELIEVE HE WAS VERY BUSY WITH THE RADIO AND CHKLISTS. FINALLY, THIS IS AN ARPT THAT WE OPERATE TO VERY OFTEN, AND THE FIELD HAD JUST GONE IFR WITH 2 1/2 MI OF VISIBILITY DUE TO DRIFTING SMOKE. I BELIEVE OUR FAMILIARITY WITH THE ARPT COUPLED WITH THE 'GOOD IFR' LED US TO ASSUME, PERHAPS UNCONSCIOUSLY, THAT THIS WOULD BE A ROUTINE AND UNEVENTFUL ARR. MANY THANKS TO THE ALERT CTLR WHO BROKE THIS CHAIN OF EVENTS. MANY LESSONS LEARNED.
