What did PNF have when he referred repeatedly to "go back down" and "According to the three you’re going up so go back down" ? From the phrasing (and maybe need to go back to the original French) would it be attitude, vs or something other ?
BEA state "Reading the three instruments (the two PFD’s and the ISIS), the PNF noticed that the airplane was climbing and asked the PF several times to descend." - how the heck they
know which instruments PNF was reading I'm not sure, but maybe the assumption is that there was no other possible source to infer "climbing". If so, then logical conclusion is that no source for that information was
unavailable...
And yet, like you, I've always wondered if attitude info was in some way lost. Post after post on here has said no way would you pull the nose over 10deg up in cruise, so it seems the only way to explain PF actions... but then not PNF comments. The HF report is going to be very interesting I think - there is much in that domain that just seems to make no sense.
