Regarding Approach Criteria, when commencing, approach minima shall be no less than which combination?

• A. 200 HAT, 1/2 Vis, 2400' RVR, whichever is higher
• B. 100 HAT, 1/4 Vis, 1200' RVR
• C. 300 HAT, 1/2 Vis, 4000' RVR
• D. 50 HAT, 3/4 Vis, 1000' RVR

Answer: (A)

Approach minima set the lowest safe altitude and visibility you must have to begin an instrument approach, ensuring you can maintain obstacle clearance and adequate visibility throughout the procedure. When an approach lists both RVR and general visibility, you apply the higher of the two thresholds to be conservative and safe. This combination provides the strictest starting point: 200 feet height above threshold, at least 1/2 mile visibility, or 2400 feet RVR, with the rule that you take whichever value is higher. That “whichever is higher” clause means you don’t start unless you meet the more restrictive of the two visibility references, which protects against marginal conditions. The other options propose lower minima (lower HAT, lower visibility, or lower RVR), which would not meet the required safety margin for commencing an approach, hence they’re not the correct choice.
