Which item is included under Alternate Weather Minima?

• A. Wind
• B. Radar
• C. Seas
• D. Ice

Answer: (A)

The concept being tested is how alternate weather minima are determined for flight planning. When you’re planning an alternate airport, you need forecast conditions that will still allow a safe approach and landing if the primary destination isn’t usable. Wind is included in these minima because wind conditions—speed, direction, and gusts—directly affect whether a given instrument approach and landing are feasible at the alternate. If the forecast wind is outside acceptable limits, the alternate may not be usable, even if other conditions look good.

Radar, seas, and ice aren’t part of the standard alternate weather minima. Radar is a tool for detecting weather, not a minimum criterion itself, and seas or ice relate to surface conditions over water or icy surfaces rather than the airport’s approach and landing minima.
