MULTIPLE AUTOFLT FAILURES PROVIDE DISTR RESULTING IN A TRACK DEV DURING AN ACR B737-800 OP.

Narrative

DSNDING THROUGH FL240 ON HEAT ARR WE LOST BOTH AUTOPLTS; BOTH FLT DIRECTORS; THE CAPT'S CDI ON NAV DISPLAY; ALL ALT WARNINGS AND PRESETS; AND ALL AIRSPD AND ALT COMMAND; SET FUNCTIONS. WHILE WE TROUBLESHOT THE PROB; I DRIFTED SLIGHTLY OFF COURSE DUE TO INATTENTION TO HIGH XWINDS AT ALTS; NO EXCUSE; JUST MY REASON WHY. NOTIFIED ATC OF THE LOSS OF OUR EQUIP IN DETAIL AND REQUESTED AND RECEIVED RADAR VECTORS TO FINAL. LANDED UNEVENTFULLY. OUR MAGIC B737 WAS BASICALLY A C152 WITH AN ILS. THIS WOULD HAVE BEEN A CHALLENGE AT NIGHT. AMAZING HOW MUCH WE RELY ON OUR COMMAND BUGS AND ALT SET WINDOW. ALT ALERT SOUNDED CONTINUOUSLY UNTIL LNDG. VERY DISTRACTING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THERE HAS BEEN NO FEEDBACK FROM MAINT AT THIS POINT AS TO THE CAUSE OF THE FAILURE. THE FAILURES MADE USE OF ANY AUTOFLT SYS UNAVAILABLE. THE RETURN TO A BASIC RAW DATA DISPLAY WITH DISTRACTING IMPROPER FLT GUIDANCE DISPLAYS THAT MUST BE IGNORED WERE DIFFICULT TO DEAL WITH. THIS WAS COMPOUNDED BY THE RPTR'S LACK OF RECENT CURRENCY IN THE ACFT CAUSED BY A MAJOR CUTBACK IN FLYING AT HIS AIRLINE.
