Pilots reports of wind shear must be issued to all arriving and departing aircraft until which event occurs?

• A. The alert is broadcast on ATIS and pilots indicate they have the appropriate ATIS code
• B. The weather radar shows no anomalies
• C. The tower closes
• D. The flight crew initiates a reduced-visibility approach

Answer: (A)

Wind-shear alerts are meant to reach every arriving and departing aircraft, so they’re shared broadly through the terminal area’s information channels. The rule ends once the alert is included in the ATIS broadcast and pilots confirm they have received the ATIS information (the appropriate ATIS code). At that point, all affected flights have access to the warning through a single, standardized source, reducing the need for ongoing individual tower announcements. The other options don’t guarantee that all crews are informed or don’t relate to how the warning is disseminated.
