CAT II landings bottom-out at what RVR?

CAT II landings bottom-out at what RVR?

• A. 800 ft. RVR
• B. 1200 ft. RVR
• C. 1600 ft. RVR
• D. 2000 ft. RVR

Answer: (B)

In CAT II landings, visibility is expressed as Runway Visual Range (RVR), which is how far you can see down the runway with the instrumentation in use. The minimum RVR for CAT II approaches is 1200 feet, paired with a decision height of about 100 feet. That 1200-foot value is the point at which CAT II minimums are authorized; if the reported RVR drops below 1200 feet, CAT II minimums cannot be used and you’d need to rely on higher minimums or go around. The other options aren’t the CAT II bottom-out value: 800 feet would be below CAT II and aligns more with stricter CAT III conditions, while 1600 or 2000 feet exceed the CAT II minimums and simply indicate better visibility than required, not the threshold at which CAT II becomes available.
