AIM ¶ 9-1-3 — Safety Alerts and Charting Notices
AIM 9-1-3 explains FAA Safety Alerts, Charting Notices, and Data Product Notices for pilots. Study guide for written tests, oral exams, and checkrides.
In Plain English
AIM 9-1-3 describes three types of notices the FAA's Aeronautical Information Services (AIS) publishes to keep pilots informed about issues or changes affecting digital aeronautical products (charts, publications, and data).
- Safety Alerts (SAs): Notify users of an error discovered or reported in a digital product. The notice identifies the specific product affected and the effective date(s).
- Charting Notices (CNs): Announce a planned enhancement to a chart or publication, along with the effective date when the change takes effect.
- Data Product Notices (DPNs): Notify users of a system outage, or alternatively a developmental upgrade to a digital product and when that upgrade goes live.
These notices matter because pilots rely on accurate, current charts and data for safe navigation. Checking the AIS website before flight planning — especially when using digital products — helps you catch known errors or upcoming changes that could affect your flight. The full listing is published at the FAA AIS Safety Alerts page referenced in the paragraph.
