Notices to Airman

The Federal Aviation Administration (FAA) is committed to permanent, measurable risk reduction in the National Airspace System (NAS). The Top 5 is derived from the output of our national Quality Assurance efforts.  It is the culmination of our proactive approach to safety management, which identifies the hazards that contribute to the highest risks identified each year.


Total number of National, International, Military and Flight Data Center (FDC) NOTAMs created between January 1, 2016, and December 31, 2016.

A NOTAM is a notice containing information that is essential to personnel concerned with flight operations but that is not known far enough in advance to be publicized by other means.     NOTAMs concern the establishment, condition, or change of any component (facility, service, procedure, or hazard) in the NAS.  They must state the abnormal status of a component of the NAS — not the normal status.

Some commonly asked questions:

Q) What is the purpose of a GPS NOTAM?

      A) To identify an area of coverage that may be affected by unreliable    
GPS signals.

Q) What does the NOTAM format look like?

      A) See examples in the FAA Order 7930.2, Notices to Airmen; the
Advisory Circular; and samples on the e-NOTAM II (ENII) website.

Q) How do I access NOTAMs on the FAA website?

      A) They are fully accessible via NOTAM Search (see reference slide)

  1. A search can be conducted on “location”, “free text”, “geographical radius”, or  “flight path”.
  2. Historical NOTAMs can be seen using the “archive” function:
    1. The NOTAM history goes back five years.
    2. You must provide a specific location on a specific date.

Q) Why do all NOTAMs have a start/stop time?

      A) Until Further Notice (UFN) and With Effect From (WEF) have been
replaced with the ICAO Start of Activity/End of Validity.

Q) When is the term “PERM” (permanent) used as the End of Validity?

      A) When NOTAM content is to be published in the U.S. Chart
Supplement or other publication.

Q) What is the difference between the Aeronautical Information Service (AIS) 24x7

    NOTAM office and the U.S. NOTAM Office?

      A) The USNOF is charged with monitoring the NOTAM System for           compliance with the criteria and procedures set in the 7930.2. Whereas the AIS office is responsible for  originating FDC NOTAMs for revisions to instrument flight procedures.
