Two questions for you Cf6, why do want to know so badly what happens in this situation which, in my company, shouldn't occur anyway.
In your considered opinion is FLCH an appropriate mode for final approach.

PS Oh and I word searched "FLCH trap" in the FCTM and Vol 1/2 of the FCOM and no results.
PPS I believe the Asiana crash may have something to do with the aircraft's speed decaying to something like Vref minus 17!
