ATIS updates should be broadcast on which frequencies to inform aircraft of a change in the ATIS code/message?

• A. Local Control
• B. Approach Control
• C. Satellite
• D. all appropriate

Answer: (D)

When ATIS information changes, the update must be spread through every channel that reaches aircraft in the area. In practice this means broadcasting the new ATIS data on the ATIS frequency and also relaying the change on other controller frequencies that serve the terminal area, such as Local Control and Approach Control. This ensures pilots hear the update whether they are on inbound, outbound, or in the terminal flow. Satellite broadcasts aren’t a standard method for disseminating ATIS changes in this context, so they aren’t applicable. Therefore, using all appropriate frequencies is the best approach to keep everyone informed.
