Which statement is correct for CAT 1 limits?

• A. 1200/600 RVR, 200' DA
• B. No restrictions
• C. 1200 RVR
• D. MDA, DH or DA

Answer: (A)

CAT I minima are defined by a precise decision altitude and required runway visual range. For a CAT I approach you descend to a fixed DA and must have the published RVR values met to continue below that point. A common CAT I set of minimums is an RVR of 1200 meters for the touchdown zone and 600 meters along the centerline, with a decision altitude of 200 feet. This combination shows both the visibility requirement and the altitude at which you may decide to land, which is why it’s the best representation of CAT I limits. The other options miss one of these elements or mix in non-CAT I concepts (like MDA, which is used for non-precision approaches).
