THS nose up
I also am stunned.
Do we know who or what caused the THS to go to 13 deg and stay there. Surely this extreme setting is a major contributor to the disaster. If this was HAL then surely Airbus has some explaining to do. I think this is not the first time the THS on an Airbus in trouble has gone to a high setting and the crew didn't notice, or am I wrong?
In my F4 a runaway stabilator trim would have been the appropriate malfunction. It was not easy to recognize in altitude hold mode, but eyewatering once autopilot did disengage.
However in that case i would assume, that HAL was trimming until running out of ideas due to the wrong airspeed indications.
