Spooky 2:
The airplane (B777) is certified to fly CAT ll approaches with the flight director only. No autopilot, no autoland required. As stated you company may have additional restrictions on this.
What about auto-throttles?
Knowing the history of the CAT II program from its inception, auto-land was not an option for early adapters. So, it is inconceivable to me that Boeing would add an auto-land requirement for CAT II in any of its auto-land birds.
They are in the business of selling airplanes with permissive operational capabilities. OTOH, a conservative, safety conscious operator might wisely not permit CAT II unless auto-land is used.
IMHO, auto-land made CAT II safe. It was a crap-shoot when hand-flown with FD and A/T to a 100-foot DA when RVR was at, or not much above, 1200 (U.S.)
And, even auto-pilot coupled CAT II approaches with those old, clunky Sperry auto-pilots in 707s, 727, and early 737s, was a high-risk operation.
