Issue: inter-pilot communication may be reduced (Issue #139)
Description: The presence of automation may reduce inter-pilot communication, possibly resulting in less sharing of information.

  2. Accession Number: 412260
    Synopsis: G3 FLC CONDUCTING GPS APCH TO MMU ARPT DID NOT IMMEDIATELY DSND FROM 4000 FT TO 2000 FT AND NEEDED TO BE PROMPTED BY THE CTLR BECAUSE OF OPPOSITE DIRECTION TFC.
    Narrative: ON IFR FLT PLAN FROM ISP TO MMU, ACFT AT 4000 FT PROCEEDING DIRECT TO SAX VOR (APPROX 260 DEG HDG) AT 200 KIAS. FINAL CTLR ISSUED A TURN TO HDG 240 DEGS, DSND TO 2000 FT, CLRED GPS RWY 23 APCH. THE PF TURNED THE ACFT TO 240 DEGS AND BEGAN SETTING UP THE FMS FOR THE GPS APCH. THE PNF DIALED IN 2000 FT IN THE ALT SELECT WINDOW AND ASKED THE PF WHAT HDG THE CTLR HAD ASSIGNED. THE PNF THEN READ BACK THE CLRNC. THE ACFT REMAINED AT 4000 FT BECAUSE THE PF DID NOT HEAR OR ACKNOWLEDGE THE ALT CHANGE. AFTER ABOUT 60 SECONDS, THE CTLR CAME BACK AND REISSUED A DSCNT TO 2000 FT STATING THERE WAS AN ACR AT OUR 12 O'CLOCK POS AND 5 MI. THE PF IMMEDIATELY DSNDED THE ACFT TO THE CORRECT ALT, THE REST OF THE FLT WAS UNEVENTFUL. THIS EVENT OCCURRED BECAUSE: 1) THIS PF DID NOT HEAR THE ALT CHANGE BECAUSE HE WAS PROGRAMMING THE FMS. 2) THE PNF DID NOT CONFIRM WITH THE PF THAT A DSCNT WAS GIVEN. 3) A REQUESTED WX GRAPHIC BECAME AVAILABLE ON THE FMS SCREEN AT THE SAME TIME AS THE CLRNC WAS ISSUED AND DISTR BOTH CREW MEMBERS. PREVENTING THE SAME PROB FROM HAPPENING AGAIN: 1) THE PF DEVOTE MOST OF HIS ATTN ON FLYING THE ACFT AND FOLLOWING ATC INSTRUCTIONS. 2) THE PNF INSURE THE PF FOLLOWS ATC INSTRUCTIONS.

  4. Accession Number: 412570
    Synopsis: B737. FO INCORRECTLY PROGRAMMED FMC.
    Narrative: ATC INDICATED CLRNC LIMIT WAS CLUCK INTXN, DUE TO DEPARTING TFC AT SITKA, WHICH I EXPLAINED TO THE COPLT, TO WHOM I WAS GIVING IOE. HE APPARENTLY THOUGHT HE HEARD ATC SAY 'CLRED DIRECT CLUCK' VERSUS 'CLRED TO CLUCK.' HE PUT DIRECT CLUCK IN THE FMC WITHOUT SAYING ANYTHING AND I MISSED THE CHANGE. A SHORT TIME LATER (5 MINS) ATC INFORMED US WE WERE ON THE WRONG AIRWAY WHICH HAPPENED TO COINCIDE WITH OUR DIRECT ROUTING. NO CONFLICT WITH OTHER TFC, BUT IT TOOK A WHILE TO SORT OUT THE MISTAKE SINCE I WAS QUITE SURE THE CORRECT ROUTING WAS IN THE BOX AND COULDN'T FIGURE OUT WHY A WAYPOINT (LYRIC) HAD DISAPPEARED. THROW IN A SHORT LEG, JNU-SIT, BAD WX, TURB, APCH TO MINIMUMS, NEW COPLT, AND THE POTENTIAL FOR CONFUSION RAPIDLY INCREASES. LESSONS LEARNED: 1) CLRED TO A FIX DOESN'T NECESSARILY MEAN CLRED DIRECT. 2) VERBALIZE AND XCHK EACH OTHER WHEN MAKING CHANGES TO THE BOX (FMC). 3) WHEN IN DOUBT -- ASK.
