charge.
Detailed information concerning FIS
−
B meteorological products can be found in Advisory Circular 00
−
45,
Aviation Weather Services, and AC 00-63, Use of Cockpit Displays of Digital Weather and Aeronautical
Information. Information on Special Use Airspace (SUA), Temporary Flight Restriction (TFR), and Notice to
Air Missions (NOTAM) products can be found in Chapters 3, 4 and 5 of this manual.

Users of FIS
−
B should familiarize themselves with the operational characteristics and limitations of the
system, including: system architecture; service environment; product lifecycles; modes of operation; and
indications of system failure.
NOTE
−
The NOTAM
−
D and NOTAM
−
FDC products broadcast via FIS
−
B are limited to those issued or effective within the past 30
days. Except for TFRs, NOTAMs older than 30 days are not provided. The pilot in command is responsible for reviewing
all necessary information prior to flight.

FIS
−
B products are updated and transmitted at specific intervals based primarily on product issuance
criteria. Update intervals are defined as the rate at which the product data is available from the source for
transmission. Transmission intervals are defined as the amount of time within which a new or updated product
transmission must be completed and/or the rate or repetition interval at which the product is rebroadcast. Update
and transmission intervals for each product are provided in TBL 7

5.
Where applicable, FIS
−
B products include a look
−
ahead range expressed in nautical miles (NM) for three
service domains: Airport Surface; Terminal Airspace; and En Route/Gulf of Mexico (GOMEX). TBL 7
provides service domain availability and look
−
ahead ranging for each FIS
−
B product.

Prior to using this capability, users should familiarize themselves with the operation of FIS
−
B avionics
by referencing the applicable User’s Guides. Guidance concerning the interpretation of information displayed
should be obtained from the appropriate avionics manufacturer.
7.
FIS
−
B malfunctions not attributed to aircraft system failures or covered by active NOTAM should be
reported by radio or telephone to the nearest FSS facility, or by sending an email to the ADS
−
B help desk at
adsb@faa.gov. Reports should include:
(a)
Condition observed;
(b)
Date and time of observation;
(c)
Altitude and location of observation;
(d)
Type and call sign of the aircraft; and
(e)
Type and software version of avionics system.

Non
−
FAA FIS Systems. Several commercial vendors also provide customers with FIS data over both the
aeronautical spectrum and on other frequencies using a variety of data link protocols. In some cases, the vendors
provide only the communications system that carries customer messages, such as the Aircraft Communications
Addressing and Reporting System (ACARS) used by many air carrier and other operators.

Operators using non
−
FAA FIS data for inflight weather and other operational information should ensure
that the products used conform to FAA/NWS standards. Specifically, aviation weather and NAS status
information should meet the following criteria:
(a)
The products should be either FAA/NWS “accepted” aviation weather reports or products, or based
on FAA/NWS accepted aviation weather reports or products. If products are used which do not meet this criteria,
they should be so identified. The operator must determine the applicability of such products to their particular
flight operations.
(b)
In the case of a weather product which is the result of the application of a process which alters the
form, function or content of the base FAA/NWS accepted weather product(s), that process, and any limitations
to the application of the resultant product, should be described in the vendor’s user guidance material. An
