A while ago I posed the question "In a FBW Airbus how would you sense which way to trim?" to smilin-ed and the answers generated show that many posters don't understand the system.
To answer my own question: "The only sense which can solve the problem is sight - look at the ECAM F/CTL page. If the elevator is neutral with sidestick released the a/c is in trim. If the elevator is displaced then trim in the same direction until elevator is neutral. This will only work with 1g demanded i.e. no sidestick deflection in pitch."
The point I wish to make to smilin-ed is that you cannot feel if the a/c in in trim (except in Direct Law). Autotrim was not the reason for this accident.
