I remember watching an initial A321 type rating sim session with a "child of the magenta line" pilot
hand-flying an ILS with F/Ds on, localizer established, flying through the glide because the PM had forgotten to arm APP.
When they realized what had happened they were almost a dot high: instead of simply pitching down and easily recovering the glide (perhaps switching off the F/Ds as per Airbus recommendations) the PF continued faithfully following the F/Ds in level flight, all the while shouting commands at the thoroughly confused PM as to what settings he now wanted on the FCU (MCP in Boeing English). Needless to say by the time they got the F/Ds to command a pitch-down it was too late and the approach became an unstable mess.
YOU fly the airplane, not the automation. If it ain't doing what you want,
you fix it, whether with a lower level of automation or by disconnecting everything and (gasp, shock horror) flying the airplane yourself, as a pilot -by definition- should be able to do.
Old grumbling f@rt rant mode OFF.
