Still some confusion of the Boeing "LAND 3" and "LAND 2" terminology (meaning three autopilot and two autopilot auto-land engaged respectively), and the ILS approach certification of "CAT III" and "CAT II".

CAT I = 200' minima, hand flown raw data is OK.
CAT II = 100' minima, pilot guidance required by the regulator, (either auto-land certified autopilot or flight director), specific pilot training.
CAT III = 50' (IIIa) down to 0' (IIIb), auto-land certified autopilot required, specific pilot training.

Companies which don't want to go the expense and bother of certifying their crews for FD guided, hand flown CAT II approaches (i.e. an exercise in the simulator) simply train for auto-land CAT III, and write a requirement for CAT II approaches to be auto-land only (avoiding the requirement for the hand flown exercise).
