Alert. The Federal NOTAM System (FNS) is currently automating the publication of Airport Construction Notice Diagrams to an Automated Closure/Restriction Notice Diagram. Manual Construction Notice Diagrams are no longer developed for airports that have not completed the automation process. To see if an airport currently has an Automated Closure/Restriction Notice Diagram (CNDA) available, search for the specific airport on the FNS NOTAM Search site, located at Federal Aviation Administration: NOTAM Search (faa.gov). The diagram will be located at the top of the search results for that airport. Additionally, you may use the following link to access a list of airports that have issued a NOTAM which has generated a CNDA: Airport Closure/Restriction NOTAM Diagrams (faa.gov).
