Narrative:

Trake 8 arrival stl under stl approach control. There is a speed restr and altitude restr at kayla landing on runway 12L/right at stl which is 250 KTS, 11000 ft. Often cleared direct ftz, cross the kayla arc at 250 KTS, 11000 ft. In our case, cleared direct ftz with restrs (restrs not restated). First officer entered waypoint abeam kayla fix with 250 KTS, 11000 ft. While in descent phase with ZKC, 2 expedited dscnts were given. Aircraft was being operated in VNAV but flight level change was exercised for 'expedited' descent. After first descent VNAV was re-entered and engaged. Same intent for second 'expedited' descent but VNAV was not re-engaged. Aircraft entered altitude hold at 11000 ft and 320 KTS. Captain, who was flying, subconsciously believed aircraft was in VNAV. 1.5 NM past kayla abeam point realized aircraft had exceeded 250 KT restr. Throttles pulled to idle and speed brakes deployed. 250 KTS obtained at 3.2 NM past kayla abeam fix. Contributing factor #1: automation. 2 methods of automatic flying -- VNAV and flight level change with different results if situational awareness not maintained. Contributing factor #2: heated discussion en route stl about cockpit preflight responsibilities. Very distracting. First officer made apologies in descent to 11000 ft. Conversation and emotional response contributed significantly to distraction!

Title: FLC EXCEEDS SPD RESTR.

Narrative: TRAKE 8 ARR STL UNDER STL APCH CTL. THERE IS A SPD RESTR AND ALT RESTR AT KAYLA LNDG ON RWY 12L/R AT STL WHICH IS 250 KTS, 11000 FT. OFTEN CLRED DIRECT FTZ, CROSS THE KAYLA ARC AT 250 KTS, 11000 FT. IN OUR CASE, CLRED DIRECT FTZ WITH RESTRS (RESTRS NOT RESTATED). FO ENTERED WAYPOINT ABEAM KAYLA FIX WITH 250 KTS, 11000 FT. WHILE IN DSCNT PHASE WITH ZKC, 2 EXPEDITED DSCNTS WERE GIVEN. ACFT WAS BEING OPERATED IN VNAV BUT FLT LEVEL CHANGE WAS EXERCISED FOR 'EXPEDITED' DSCNT. AFTER FIRST DSCNT VNAV WAS RE-ENTERED AND ENGAGED. SAME INTENT FOR SECOND 'EXPEDITED' DSCNT BUT VNAV WAS NOT RE-ENGAGED. ACFT ENTERED ALT HOLD AT 11000 FT AND 320 KTS. CAPT, WHO WAS FLYING, SUBCONSCIOUSLY BELIEVED ACFT WAS IN VNAV. 1.5 NM PAST KAYLA ABEAM POINT REALIZED ACFT HAD EXCEEDED 250 KT RESTR. THROTTLES PULLED TO IDLE AND SPD BRAKES DEPLOYED. 250 KTS OBTAINED AT 3.2 NM PAST KAYLA ABEAM FIX. CONTRIBUTING FACTOR #1: AUTOMATION. 2 METHODS OF AUTOMATIC FLYING -- VNAV AND FLT LEVEL CHANGE WITH DIFFERENT RESULTS IF SITUATIONAL AWARENESS NOT MAINTAINED. CONTRIBUTING FACTOR #2: HEATED DISCUSSION ENRTE STL ABOUT COCKPIT PREFLT RESPONSIBILITIES. VERY DISTRACTING. FO MADE APOLOGIES IN DSCNT TO 11000 FT. CONVERSATION AND EMOTIONAL RESPONSE CONTRIBUTED SIGNIFICANTLY TO DISTR!
