Approach
I am an old pilot who has not had the joy of all the automation gobbledegook and I get rather disgusted with all the acronym-driven jargon about what or what was not on and this or that was engaged or charged that caused the undershoot. It was a clear, a no-wind day and the airplane was doing everything that it should have. The target that was the end of the runway was in sight, if the target moved up you add power. If it moves down, you retard power. You concentrate on where you want to land and act accordingly...but then, that is if you are a pilot.
