suninmyeyes, thanks for an excellent and thoughtful explanation.

I would add / ask that the differences between previous A320 experience and the B777 may also have had influence, e.g. A320 autothrust when engaged will maintain speed without thrust lever movement, as in this accident.
What are the equivalent correct/incorrect A320 autothrust annunciations?
Does type training pay enough attention to these differences?

Also, the flight technique – raising the nose, should be based on the ‘normal’ picture, the attitude with respect to the real world for the aircraft type; had this pilot sufficient experience on this type to establish a normal picture?

Would the crew have any additional cue of speed error from the control force, assuming it deviated from the trim condition; or does the B777 have an auto trim follow-up system in manual flight?

I would disagree about not changing SFO procedures; previous success is not evidence of safe – acceptable risk operations. Accidents are a combination of factors – “the unforeseen and often unforeseeable concatenation (linking) of diverse events, each one necessary, but singularly insufficient.” (James Reason).

“The landing checklist was not completed until …” We often ‘kill time’, but lack of it can be a real killer; how many occasions did your post refer to time.
