What is the instrument approach minimum adjustment for a High Minimum Captain at origin or destination?

• A. Add 100 feet to the ceiling and ½ mile to visibility.
• B. Add 200 feet to the ceiling and 2 miles to visibility.
• C. No adjustment.
• D. Increase by 300 feet and 2 miles.

Answer: (A)

High Minimum Captain operations require higher instrument approach minimums to maintain safe margins when conditions or pilot factors make precise reference to the runway environment more challenging. The standard adjustment for this authorization is to increase the published minimums modestly: add 100 feet to the altitude (ceiling) and add 1/2 mile to the visibility. This reflects the added risk without being overly restrictive, ensuring the crew only continues the approach if the weather and visibility are clearly sufficient to maintain proper obstacle clearance and runway reference. So, if the base minima are, say, a certain altitude and a certain visibility, you would use those same minima increased by 100 feet and 0.5 mile for a High Minimum Captain at origin or destination. The other options propose larger increases or no adjustment, which do not align with the standard practice for this authorization.
