Wind speed will only be given on a GFA when it is expected to be greater than:

The correct answer is based on the standards set for issuing wind information in a General Aviation Forecast (GFA). In aviation, specific thresholds are established to ensure that only relevant and significant data is communicated to pilots for their planning and operational needs.

Wind speed will only be reported on a GFA when it is expected to be greater than 20 knots because this is considered a threshold at which wind could significantly affect flight operations, particularly for helicopters which are more susceptible to wind effects than larger aircraft. Wind at or below this threshold is generally not specified as it may not materially impact flight safety or performance. Instead, forecasts at lower wind speeds tend to provide a more concise overview that helps pilots focus on significant factors that could affect their operations.

Understanding this standard is critical for pilots and operators as it aids in interpreting weather information accurately and enhances situational awareness during flight planning and execution.
