A/P Disconnect
I haven't seen a discrete S/W parameter listed. The A/P is disconnected by S/W Pusher but the pusher is inhibited in slats retract therefore the disconnect at about 1:45min and 31sec was not due to S/W. As for the reason for not extending the slats from a clean config, this was due to concern for a failure causing slat extension at cruise.

Reason: Had forgot that there is no pusher clean.
