What is the meaning of the WND DATA ESTMD remark?

• A. To indicate wind data is verified
• B. To indicate wind data is from the active end
• C. To indicate wind data is estimated due to outage
• D. To indicate wind data is ignored

Answer: (C)

WND DATA ESTMD means the wind information is estimated because the wind sensor or data path is out of service. When a wind sensor is offline or its signal is unusable, the system fills in the wind values using other data sources (such as models or nearby observations) and flags the result as an estimate. This warns you that the wind data aren’t directly observed and may be less reliable, so you’d use caution or seek alternate wind information if precise winds are critical. It isn’t indicating verified data, nor that the data comes from the active end, nor that the data is ignored.
