Most of you may not recognize what sensor_validation is doing with his analysis, but if anyone is familiar with the communication analysis techniques of Sidney Dekker in (for example) "The Field Guide to Understanding Human Error" (a highly recommended read) they will recognize the process.

Sensor_validation gets a big attaboy for those initial efforts.
There is a lot that can be learned from this type of analysis process.
Gotta go and read that ref now - but we are just given a glimpse into the mindset of the the BEA investigators who can't say what they are not certain about, or AF / AB could object to - but sure they will by now have more potentially controversial 'facts' and theories. I hope they can recreate what speed indication was on the RHS display.

On consulting mon interprète there's little doubt "réveille" means "wake", but perhaps there's nothing in the captain "assiste" rather than just "attend" the handover, and the PNF "éventuellement" translated to "maybe" could have been "possibly" and not be passive in context - but why did BEA highlight that but not whose decision to reduce speed. Maybe they wanted to make the point he was fresh and alert after "power napping"?

By the way - if you study the A340 airprox Appendix B zoom climb it appears (as has been pointed out before in this thread) pitch-down commands are plotted as positive which is somewhat counter-intuitive isn't it?
