I have often suggested that in the same way that we had to do three auto-lands in any 6 month period to keep our currency up, and keep a record of that; we should be required by pilot training management do three fully manual raw data ILS approaches. On reasonable weather days and 'reasonable airspace' days, of course.
If we were actually mandated to do three manually flown, manual thrust raw data ILS approaches - with no FDs either - in every 6 month period; it just might coax all of us out of our safety blankets, and keep our manual skills from rusting too far, (me included !).
