Definition
An official notice issued by the FAA's Aeronautical Information Services to alert users of changes, errors, or important information affecting a published aeronautical chart or related navigation product between regular publication cycles.
Plain English
A bulletin from the FAA that tells pilots about a problem, correction, or update to one of their charts or navigation publications before the next scheduled edition comes out.
Context Anchor
Seen when checking current aviation charts, chart supplements, airport information, or electronic navigation data before a flight.
Why Pilots Care
Using outdated or incorrect data can lead to navigation errors or flight planning mistakes, so pilots must know when a data product has changed.
Intuition Check
Do not read this as a general message about computer data. In aviation, a Data Product Notice is tied to official aviation information products and points out changes or corrections that may affect safe use of them.
Example Sentence 1
Before the cross-country flight, she checked the FAA website for any Data Product Notice that might affect her sectional chart.
Example Sentence 2
A Data Product Notice warned operators of a temporary outage in the terrain awareness data feed.
