But "on a perdu les les les vitesses" is more probably related to the disappearance of some speed symbols and is not a positive indication of UAS.
But then why is the PF response to that "okay, okay okay je redescends". That line makes no sense to me - maybe PF was saying speed but pointing at altitude
Because the PF was conscious that he had gained altitude which was detrimental to the speed. He did agree to go back down, but never took the necessary attitude to do so …
IMO they have never understand their initial problem and the reason for the AP A/THR DISC was a case of UAS.
Thanks for the links on the previous threads.
report would be 1000s of pages
It is not a good reason.
Remember, the accident is a consequence of a scenario of UAS initially, so it is imperative for the BEA to develop comment and analyze anything related to that matter. Of course
NAV IAS DISCREPANCY ECAM MSG or the BUSS function have to be mentioned. It would require 10 pages at most not 800.
We know AF didn't take BUSS option, I've seen rumours (maybe here) that they thought it wasn't any good ("useless" above FL26)
By procedure the BUSS is not to be used above 25000 feet.
IMO that equipment for AF447 would not have done the slightest difference to the outcome.
