Pilot flying flies and monitors communication whilst non flying pilot Assists in managing the abnormality or emergency.PF can always in 3 seconds say "Mayday mayday mayday Flt 804.Stby further..or PNF can activate the emergency transponder code..part of the procefure in an emergency descent...which if so should have been controllable unless there was fire in the rear and tailplane electrics affected to have lost control.
from 37000 ft its a long drop and if in the radio blind spot they couldnt alert anyone on radio but transonder would have alerted radar controllers.
The ANC (Av Nav Com) is just a guide fellas..not the grail@
Lets hear what the CVR and FDR have to say but too early to tule out technical failure. We are still in the recovery phase.Terrorism shouldnt even be factored until after forensics.Lets not Trump our way into "100% terrorism"...it is too brash.
