NOTAMS & TFR'S
NOTE: The below websites
are a cooperative venture by the F.A.A. and U.S. military. Their data base is focused on airports which
may routinely or occasionally provide services and support to military operations. While this list is extensive, it DOES
NOT provide NOTAM-D data for all public use airports.
Many international airports are also supported.

A WORD ON... "NOTAMS"
When checking for NOTAMS, keep in mind that there are multiple types and sources of NOTAMS, many of which are not available on the
Internet. The information found at the above website will only contain NOTAM-D related data for airports which may have the ability to support
military operations. Other sources will contain "Local" NOTAMS, "Class II " NOTAMS and "Flight Data Center" (FDC) NOTAMS. Once the
information contained in a NOTAM is published in documents such as the "Airport Facility Directory" and all related charts, it will be removed
from the NOTAM-D database. Absence or cancellation of a NOTAM does not necessarily mean an airport runway is no longer closed, for
example... it may merely mean that the data has been transferred to another medium of providing information.
YOU MUST CONSULT ALL AVAILABLE NOTAM SOURCES
The "Airport Facility Directory" is published every 56 days (always on a Thursday), on the same cycle as most other instrument charts. Once
information is published in this booklet, and the data would not normally be promulgated elsewhere, a related NOTAM will be canceled by the
originating facility....and at that time, will no longer be available in the AFSS/FSS computer system. Information which is displayed on sectionals,
TCA and WAC charts, are frequently subject to a longer period beween updates, as these items are printed at longer intervals.
NOTAM-D information is generally restrictive in nature. Examples include items such as reporting the closing of an airport, closing all or part of a
runway, non availability of a navigational aid, or activity in restricted airspace. In effect, a NOTAM-D might be thought of as removing any
options with regard to usage of the subject facility.
"FDC NOTAMS" are regulatory in nature...and as the name implies, are issued by the National Flight Data Center. FDC NOTAMS may pertain
to a variety of subjects, including special emergency airspace restrictions, navigational aid limitations, international airspace revisions and
revisions to IFR approach procedures. Newly issued FDC NOTAMS will normally be available in the AFSS/FSS database, but once published,
they may no longer be available except in the "Class II" NOTAM publication, in addition to materials provided with approach plate subscription
material.
"LOCAL NOTAMS" apply to equipment and procedures which will have a lesser, but never-the-less significant impact on aircraft operations.
LOCAL NOTAMS will pertain to circumstances which may exist, but do not prohibit the use of an airport or runway, except for a brief (less than 1
hour) period of time. A "LOCAL NOTAM" will not preclude you from landing, for example. The number of "LOCAL NOTAMS" for an
aerodrome may frequently exceed that of NOTAM-D information. It is entirely possible, if not likely, that "LOCAL NOTAMS" may exist,
without any "NOTAM-D" information being in force. The shear volume of "LOCAL NOTAMS" has long presented a challenge to the related
F.A.A. computer systems. There is simply no existing F.A.A. computer which has the capacity to process all "NOTAM-L" information on a
national basis. For this reason, it is important to remember that "NOTAM-L" data is normally, only available at the AFSS/FSS which is the
primary facility providing services for the concerned airport. NOTAM-L information for a distant destination (generally out of the state or service
area) is not normally available at an AFSS/FSS. If there are questions which you feel need to be resolved, it is best to call the AFSS/FSS which
serves your destination airport and/or call the airport manager. This is also important to remember when you are receiving a briefing from a
facility which is providing "augmented service" to your home state or region, due to heavy traffic demands on your "home" facility. It thus
becomes increasingly important to be aware of which facility you are talking to on the "800" number, for example.
"Class II NOTAMS" are part of a process which converts a NOTAM to print... or otherwise is a means of publishing NOTAM information for a
prolonged period of time. In effect, a "CLASS II NOTAM" is data which exists in a printed medium. CLASS II NOTAMS may contain the subject
of NOTAM-D's, FDC NOTAMS and NOTAM-L's. All AFSS & FSS's have printed "CLASS II NOTAMS" available in the facility. An important
thing to remember is, that an F.A.A. briefer will not normally provide "CLASS II NOTAM" information, unless you specifically request it as part
of the briefing. The assumption in this case, is that you subscribe or have access to the printed material.
"MILITARY NOTAMS" have long been a source of challenges for the F.A.A. NOTAM distribution system. Non U.S. Army military aerodrome
NOTAMS are normally not available through the AFSS/FSS system, except through a cumbersome and time consuming process... which is
probably one of the best of all reasons the above NOTAM website was created.
"INTERNATIONAL NOTAMS" provide good reason to mention a "caveat" at this point. You may be able to retrieve many of the desired
"INTERNATIONAL NOTAMS" by using the above website. It is important to remember that lapses and delays in exchange of NOTAM related
information can and do occur. For this reason, a recommended practice would be to obtain NOTAM information from the nation of origin at the
first opportunity. The F.A.A. requires AFSS/FSS briefers to make the following statement, during the course of a briefing for an international
flight... and it most especially applies to NOTAM information. . . "INTERNATIONAL NOTAMS" may also be printed in a "CLASS II"
publication.
"Check data as soon as practical after entering foreign airspace, as our international data may
be inaccurate or incomplete".
