You are correct, a low level altitude capture would back off the throttles as the FMA goes into ALT. However the FD would drop unexpectedly as would the engine noise as the throttles rolled back..... So in what world would that prompt you to call for the dual engine failure checklist rather than firewalling the throttles? This was discussed about 75 pages ago.... It makes good reading

If we assume that the report is factual, as there is no good reason to think otherwise, then the aircraft was serviceable and there were no faults, messages or warnings right up to the point the FCSs were moved to cutoff, as they would have been detailed in the report. The only unresolved question is why was this done?
Putting deliberate action to one side, if the FO was the PF in manual flight, as SOP the captain as PM would be making any configuration changes, MCP selections or switch movements. We know that the captain was a trainer and as such, it is likely that he was used to running details both from the instructor station and either seat. Given the constraints on simulator time and ever-increasing syllabi it is not uncommon for trainers to physically reset the sim to save time and that includes moving critical controls without diagnosis or confirmation in ways inappropriate for the phase of flight, even if frozen. It is likely that if you were doing a lot of training, you would become more practiced at this than the SOP multi-crew interactive method and unknowingly build a semi-autonomous routine in your mind that allowed these type of actions as there was no jeopardy. Normal line pilots are only trained/practiced/checked on the correct way of doing these. I\x92m not saying that this is what happened, just offering one possibility as to how a competent crew could end up in a disastrous scenario and experience post-decision dissonance over what had just transpired.

Back in the days before it became illegal I used to blag my way into the cockpit on short haul flights using my RAF ID card. Part of the cockpit checks, if the third seat was occupied, was the question "Pax, seat belt on and secure?" to which I always responded "Seat Belt on and secure". I am sure that that Question and Response is still used on check lists and if that is the case that Q&R would have been recorded on the CVR. That should, hopefully, do away with the 'third person in the cockpit\x94 theory ACW342
As far as the gear lever being in the down position in the wreckage, it could be that the engine shutdowns occurred before the positive rate call and/or the gear was selected up but put down again when a forced landing became inevitable. The only paraphrased communication we have is to do with the engine controls - there was probably more but the preliminary report has omitted it because it\x92s not really relevant to the main event?

The more I ponder on this the more I feel like the final outcome may be very unsatisfying-we may get a detailed report on the how but not the why and the result will become a
Rorschach test- we will apply our own biases and come to our own judgements
already I don\x92t know how we\x92d ever be able to prove intent vs action slip unless there\x92s a \x91note\x92 recovered at one of their homes (but you\x92d have thought that would\x92ve been known already long ago) no one\x92s life is perfect nor can we know what anyone is really dealing with internally vs their external persona Subjects (links are to this post in the relevant subject page so that this post can be seen in context): Action slip |
