wonder if Boeing FBW AT pilots cover TL's or just trust, and only place hands on for TOGA selection? (I hear an AB GA is initiated by manually fire walling TL's, but do you cover them on approaches?)
Off course you follow them in any aircraft. Using automation the scan remains same but it is for monitoring of automation effecting changes. During approach pilot has to keep his hand on throttles/ thrust levers. Even in airbus the last point is 1000ft AAL although you can't follow thrust levers but like this accident things can happen so fast it's not a good idea to go searching for them
