CAT IIIB (CAT III DUAL) autoland minimums are:

CAT IIIB (CAT III DUAL) autoland minimums are:

• A. CAT IIIB DUAL: 100' AH / 300 RVR; Both autopilot; Yes A/THR
• B. CAT IIIB DUAL: 100' DH / 1000 RVR; One autopilot; No A/THR
• C. CAT II (CAT II, CAT III SINGLE, OR CAT III DUAL): 100' DH / 1000 RVR; One autopilot; No A/THR
• D. CAT IIIA SINGLE: 50' DH / 600 RVR; One autopilot; Yes A/THR

Answer: (A)

Autoland minimums depend on how much automation is available and used. When CAT IIIB autoland is configured with dual autopilots engaged and autothrust active, the system can operate at the lowest allowed visibility and height. The minimum in this setup is 100 feet height (AH) and 300 meters RVR, provided both autopilots stay engaged and autothrust is on. That matches the option stating 100' AH / 300 RVR with Both autopilot and Yes A/THR. If you only have one autopilot, the minima move up, such as 1000 RVR, and the autoland capability is reduced. Other choices reflect different categories or single-autopilot scenarios (e.g., CAT IIIA SINGLE or higher RVR).
