FLT CREW OF WDB UNABLE TO COMPLY WITH XING RESTR ON CLANG ARR TO IND.

Narrative

ACFT WAS ON DSCNT ON CLANG 5 ARR INTO INDIANAPOLIS. AUTOPLT WAS ENGAGED; PROFILE MODE SELECTED. WE HAD RECEIVED CLRNC TO CROSS PENDS INTXN AT 11000 FT; 250 KTS FOR APCH TO RWY 23L. WE HAD RECEIVED A SERIES OF STEP-DOWNS IN ALT STARTING 150 MI OUT. WE WERE CLRED OUT OF FL250 TO 11000 FT AND THE ACFT STARTED DOWN. PROFILE WAS NOT MAINTAINING THE DESIRED AIRSPD; SO I ELECTED TO EXTEND THE SPDBRAKE. I THEN REALIZED THAT WE WERE ONLY A FEW MI FROM PENDS AND WOULD NOT BE ABLE TO COMPLY WITH THE XING RESTRS. I ASKED THE CAPT (PNF) TO INFORM THE CTLR; BUT THERE WAS SO MUCH RADIO CHATTER; HE COULD NOT GET A WORD IN EDGEWISE BEFORE WE WERE SENT TO A DIFFERENT FREQ. HE HAD BEEN HEADS DOWN CALLING UP ATIS ON THE ACARS; AND DID NOT SEE THE EVENTS DEVELOPING. WE WERE BOTH HIGHLY EXPERIENCED IN THE ACFT; HAD FLOWN TOGETHER NUMEROUS TIMES; AND WERE VERY FAMILIAR (TOO FAMILIAR?) WITH THE ARPT. THE FAMILIARITY PROBABLY LED TO COMPLACENCY. ALSO; USING PROFILE DSCNT MODE LULLED ME INTO A FALSE SENSE THAT THE ACFT WOULD AUTOMATICALLY MEET THE PROGRAMMED RESTRS. I WAS ALSO PREOCCUPIED; IN MY OWN MIND; WITH TRYING TO MENTALLY WORK OUT MY SCHEDULE FOR THE NEXT FEW DAYS WHO WOULD GET KIDS TO AND FROM SCHOOL; WHEN WOULD I HAVE TIME TO GROCERY SHOP; WHAT TIME TO BID TO HAVE TIME OFF FOR MY ELDERLY FATHER'S SURGERY; ETC. I IGNORED THE BASIC TENANT OF AVIATION FIRST. FLY THE AIRPLANE! (NOTE: MENOPAUSAL HEAT FLASHES CAUSING EXTREME DISCOMFORT WAS AN ADDED DISTR.)
