Well, setting DDA using the autopilot to descend to the DDA but then prior to reaching 1000 AGL it calls for us to set missed approach altitude. That means if the pilots aren’t really well in front of the plane, the airplane will continue descending below DDA with nothing but proficiency/egpws or the ground to stop it.
