If an alternate minimums procedure has no listed minima for a nonprecision approach, what are the standard alternate minimums?

• A. 600 ft ceiling and 2 miles visibility
• B. 800 ft ceiling and 2 miles visibility
• C. 1000 ft ceiling and 3 miles visibility
• D. 400 ft ceiling and 1 mile visibility

Answer: (B)

When choosing an alternate, if the approach at that airport has no published alternate minima, you apply the standard alternate minimums. For a nonprecision approach, the standard alternate minimums are 800 ft of ceiling and 2 miles of visibility. This conservative baseline accounts for the lack of vertical guidance on a nonprecision approach, giving enough obstacle clearance and reliability for an alternate landing scenario. The other options either fall below this fallback standard or apply to different approach categories (for example, 1,000 ft and 3 miles is typical for precision approaches), or are simply too low to be considered usable alternate weather.
