Assuming the OZ 214 crew were indeed set up for the RNAV (GPS) Rwy 28L (posted earlier on this thread), a couple of possible gotcha's other than the FLCH trap come to mind.

If the crew forgot to set missed approach altitude in the MCP window after passing DUYET with the autothrottles on and the autopilot off in VNAV wouldn't they get an altitude capture at DA (not sure whether OZ does LPV or LNAV/VNAV)? Attempting to raise the nose to correct for a shallow approach angle would bring the throttles back to idle, right?

Also, if the aircraft altimeter setting was not correct, with a higher QNH set in the plane than actual, the VNAV path would lead to a point short of the runway with instruments showing on profile all the way down. Crossing altitudes would look fine but the RA would not cross check (at least on an LNAV/VNAV approach, I don't believe you would get the wrong path on an LPV with WAAS even with a bad baro setting).

Obviously, someone should be looking out the window on a day visual approach with CAVOK weather.

I've never flown the Triple but on other Boeings the altitude capture and wrong altimeter setting can ruin your whole day on a non-precision approach if you don't take immediate corrective action.
