What factor would NOT be directly considered in a GFA report?

In a Graphical Area Forecast (GFA) report, the primary factors evaluated are those that directly impact aviation safety and operations, such as visibility, cloud cover, and significant weather conditions that could affect flight.

Temperature is generally considered less critical in GFA reports since the primary intent is to provide information that is most relevant to pilots and aviation operations. While temperature can influence weather conditions and phenomena like turbulence or icing, it is not typically included as a direct element of the forecast. Visibility, cloud cover, and humidity are all vital components that pilots need to assess potential flying conditions, while temperature tends to be more of a secondary consideration in this context.

Therefore, the correct answer being temperature aligns with the focus on immediate weather variables usually presented in GFA reports, which prioritize those factors most relevant to flight safety.
