Which statement about wind data during outages is correct?

• A. Always use forecast winds
• B. Do not report wind data
• C. Use data from the active end only
• D. Use wind data with a WND DATA ESTMD remark indicating it is estimated

Answer: (D)

When wind data isn’t actively measurable due to outages, the value used should be clearly identified as not being a direct observation. The correct approach is to use the available wind data but append a WND DATA ESTMD remark to indicate it is estimated. This labeling communicates that the value is derived from the best available information and not a fresh measurement, which helps everyone interpret the data correctly and make safer decisions. This avoids giving a false impression of certainty that would come with forecast winds or with unmarked data. It also prevents withholding wind information entirely, which could leave crews under-informed. Marking the data as estimated maintains transparency about reliability while still providing actionable guidance.
