(a) Amendments to published IAPs and other current aeronautical charts. 

(b) Temporary Flight Restrictions (TFR). Pilots should read NOTAMs in their entirety as some TFRs may allow pilots to fly through the flight restriction should they request permission to do so and subsequently receive it. Pilots are encouraged to use online preflight resources as they provide graphics and plain language interpretations for TFRs. 

(e) ADS − B, TIS − B, and FIS − B service availability. 

(f) Satellite − based systems such as WAAS or GPS. 

## 3. International NOTAMs. 

(a) Distributed to more than one country, they are published in ICAO format under guidelines established in Annex 15. International NOTAMs issued by the U.S. NOTAM Office use Series A followed by 4 sequential numbers, a slant “/” and a 2 − digit number representing the year the NOTAM was issued. For the most part, International NOTAMs duplicate data found in a U.S. Domestic NOTAM. 

(b) Not every topic of a U.S. Domestic NOTAM is issued as an International NOTAM by the U.S. When possible, the U.S. International NOTAM will be linked to the appropriate U.S. Domestic NOTAM. 

(c) International NOTAMs received by the FAA from other countries are stored in the U.S. NOTAM System. 

(d) The International NOTAM format in- cludes a “Q” Line that can be easily read/parsed by a 

(c) High barometric pressure warning. 

(d) Laser light activity. 

(g) Special Notices. 

computer and allows the NOTAM to be displayed digitally. 

(1) Field A: ICAO location identifier or FIR affected by the NOTAM. 

(3) Field C: End of Validity (both in [Year][Month][Day][Hour][Minute] format). 

(6) Field F: (when present) Lowest altitude, or “SFC.” 

(7) Field G: (when present) Highest altitude, or “UNL.” 

(e) For more on International format, please see Annex 15. 

4. Military NOTAMs. NOTAMs originated by the U.S. Air Force, Army, Marine, or Navy, and pertaining to military or joint − use navigational aids/airports that are part of the NAS. Military NOTAMs are published in the International NOTAM format and should be reviewed by users of a military or joint − use facility. 

## g. Security NOTAMS: 

1. U.S. Domestic Security NOTAMS are FDC NOTAMS that inform pilots of certain U.S. security activities or requirements, such as Special Security Instructions for aircraft operations to, from, within, or transitioning U.S. territorial airspace. These NO- TAMS are found on the Federal NOTAM System (FNS) NOTAM Search website under the location designator KZZZ. 

2. United States International Flight Prohibi- tions, Potential Hostile Situations, and Foreign Notices are issued by the FAA and are found on the Federal NOTAM System (FNS) NOTAM Search website under the location designator KICZ. 

(2) Field B: Start of Validity. 

(4) Field D: (when present) Schedule. 

(5) Field E: Full NOTAM description.
