Just got this from pprune.org on Airbus pilots discussing the accident...
According to Finnish CAA in Finnish newpaper Helsingin Sanomat, the CVR has revealed crew was unconscious in the start of descent. So looks like Helios 2.
So indeed it does appear it is like the Greek accident of Helios airline.
And the Airbus 320 the book says for emergency descent:
PNF PF
1. ST BELT ON 1. TURN ALT, PULL ALT
2. ENG MODE SEL IGN 2. TURN HDG, PULL HDG
3.ATC CODE 7700 3. PULL SPEED
4.ATC MAYDAY 4. SPEED BRAKE EXTENDED
5. PAX SYZ ON I'm guessing they never got past PF1 before they were unconscious. Also, the Airbus has built in overspeed protection - so they may have just disengaged the autopilot before going unconscious - and it went nose down - and even with full throttle the overspeed protection on descent kicks in...again just speculation.
Either way, very sad.
