How do ILS Category I, II, and III differ in decision height and runway visual range requirements?

• A. CAT I has higher minima (e.g., DH around 200 ft, RVR around 2400 ft); CAT II/III have progressively lower minima, enabling operations in worse visibility.
• B. CAT I has the lowest minima; CAT II and III have higher
• C. All categories require the same minima
• D. DH distances are not used

Answer: (D)
