Category III Operations refer to:

Category III Operations refer to:

• A. An ILS approach to the runway using a Category III ILS instrument approach procedure.
• B. A GPS approach.
• C. A localizer approach.
• D. A non-precision approach.

Answer: (A)

Category III operations refer to landing using the ILS with the most advanced, very low visibility minimums. This is a high-level precision approach that provides both lateral and vertical guidance and often requires automatic landing or autopilot coupling to fly and land the aircraft under extremely poor visibility. Because of the specialized lighting, instrumentation, and procedures, only an ILS with Category III capability supports these minimums. GPS approaches, localizer (lateral guidance only), or other non-precision approaches do not carry Category III minima. So the best description is an ILS approach to the runway using a Category III ILS procedure.
