Complete the LLWS alert dissemination rule: 'Controllers must issue LLWS alerts to ______ until ______ and pilot advises they have received the code'

• A. All arriving and departing aircraft; Broadcast on ATIS
• B. Only inbound aircraft; Broadcast on the radio
• C. All aircraft in airspace; Broadcast on the internet
• D. Ground personnel; Announced in the cab

Answer: (A)

The key idea here is rapid, universal awareness for pilots about low-level wind shear hazards. LLWS alerts must be issued to all arriving and departing aircraft so every flight in the terminal area has the same warning, since wind shear can develop quickly and affect both approaches and departures. Broadcasting the alert on ATIS gives pilots in the vicinity a consistent, widely reachable source of information without needing to contact a specific controller, which helps ensure no aircraft misses the warning.

The rule also requires the pilot to advise they have received the code, so there’s a verified acknowledgment that the alert reached the cockpit. This combination—disseminating to all arriving and departing traffic and using ATIS as the dissemination channel, with pilot confirmation—ensures reliable, broad awareness.

Other methods listed wouldn’t guarantee that all relevant aircraft receive the message in time (for example, inbound-only targeting would miss departures; relying on a radio call to individual aircraft isn’t universal; internet postings or ground-crew announcements don’t reach the flight deck during operations).
