Which surface wind information is not transmitted long-line to the aircrew?

The correct choice pertains to the type of surface wind information that is not typically transmitted long-line to the aircrew. Locally reported surface winds from on-field observation resources are often used for immediate and localized assessments, but these reports are generally not included in the long-line transmission that is standard for operational flights. Long-line transmissions focus primarily on more standardized data collected and reported from meteorological sources and systems that provide a broader view of conditions, rather than localized observations which might vary significantly even within short distances.

In contrast, winds from meteorological buildings are systematically gathered, processed, and disseminated to ensure that aircrew receive the most relevant and accurate data for their flight operations. Forecasted winds from air traffic control are based on predicted patterns and are made available for aircrew to anticipate changing conditions. Wind speeds reported by nearby aircraft also contribute vital real-time information that is beneficial for operational awareness and flight planning, ensuring that flight crews are informed of changing atmospheric conditions as they relate to their route and altitude.
