Category II Operations refer to:

• A. A straight-in ILS approach to the runway under a Category II ILS instrument approach procedure.
• B. A non-precision localizer approach.
• C. A circling approach.
• D. A visual approach.

Answer: (A)

Category II Operations involve landing using an ILS Category II approach, which is an instrument approach with lower minimums than a standard Category I. This allows a straight-in landing when weather conditions and required equipment meet Cat II standards, typically with a reduced decision height and visibility. It’s specifically tied to the ILS approach procedure and the associated minimums, rather than just any localizer, circling, or visual approach. The other options describe different types of approaches or procedures that do not imply Cat II minima.
