I know if you shoot a cat III ILS the aircraft needs autopilot and autothrottle. But what about cat II? And yes I also know you need an endorsement for both.

Mu2, that's going to depend on the level of CAT III approach. Our dash 8's must be hand flown on a CAT III(a) approach as they are incapable of an auto-pilot coupled approach. For CAT III autoland obviously auto-pilot and auto-throttle are needed.

CAT II can go either way also, however if certain systems are inop it affects the certification of the reduced viz landing capability.

Our ATRs required autopilot for Cat ll; they have no autothrottle. And no Autoland of course.

The RJ 100s and 737s obviously require A/P, but neither require A/T for a Cat ll, although A/T would be routinely used. Lack of A/T makes no diff. to the approach minima. Both types can be manually or auto landed from a Cat ll.

Qualifications and requirements (my company) -
xxx
Cat.II and Cat.IIIa operations - 747-200...
There are crew qualified for Cat.II only, not Cat.IIIa.
Any crewmember qualified for Cat.IIIa is also qualified for Cat.II...
Both pilots must be trained, current and qualified for such approaches.
xxx
The aircraft must be certified and maintained to Cat.II or Cat.IIIa standards.
Two autopilots are sufficient for Cat.II certification (company requirement)
Three autopilots required for Cat.IIIa certification (company requirement)
xxx
In training (simulator) all pilots are trained to "hand fly" a Cat.II approach.
New pilots must have more than 100 hours as 747 captain to fly Cat.II minimums.
They also must have more than 200 hours to fly Cat.IIIa minimums.
These are all the basic requirements. Realize, they are specific to this airline.
