Logic suggests that having an auto throttle "wake up" in the flare to landing, for example, might be sub-optimal! In other words, it's probably designed to stay "asleep" under certain conditions.
Even without the auto throttle, there's still the airspeed tape unwinding; that should be a primary flight instrument that's included in your scan. Well, that's how it works for Microsoft Flight Simulator, anyway. Is it different on a Boeing 777?
This is going to be an interesting accident report. Would anyone like to take a guess if the Korean authorities might disagree with whatever the NTSB has to say, as the Egyptians did after that accident they had?
