2-5-1. AUTOMATIC FLIGHT INFORMATION
SERVICE (AFIS)
Use the AFIS to provide advance noncontrol airport,
meteorological, and pertinent NOTAM information
to aircraft. Specialists must provide local airport
advisory (LAA) information when the AFIS is not
available.
NOTE-
Use of the AFIS by pilots is not mandatory, but pilots who
use twoway radio communication with the FSS are urged
to use the service.
a. Begin each new AFIS message with the
airport/facility name and a phonetic alphabet letter.
The phonetic alphabet letter must also be spoken at
the end of the message and be used sequentially,
beginning with “Alfa,” ending with “Zulu.”
Fulltime facilities must repeat the letter without
regard to the beginning of a new day. Part-time
facilities must identify the first resumed broadcast
message with “Alfa.”
b. The AFIS recording must be reviewed for
completeness, accuracy, speech rate, and proper
enunciation before being transmitted.
c. Maintain an AFIS message that reflects the
most current local airport information.
1. Make a new AFIS recording when any of the
following occur:
(a) Upon receipt of any new official weather,
regardless of any change in values.
(b) When runway braking action reports are
received that indicate runway braking is worse than
that which was included in the current AFIS
broadcast.
(c) When there is a change in any other
pertinent data for the airport or surrounding area, such
as change in favored runway, new or canceled
NOTAMs, WAs, WSs, CWAs, PIREPs, or other
information that facilitates the repetitive
transmission of essential but routine information.
2. Omit rapidly changing data. When this
occurs, the AFIS must contain a statement advising
pilots whom to contact for the omitted data.
EXAMPLE-
“For latest ceiling/visibility/altimeter/wind/(other conditions) contact (facility and frequency).”
3. Broadcast, on the LAA frequency, the new
airport AFIS phonetic alphabet identifier after each
new recording.
4. After establishing twoway radio communication, if the pilot does not state that he/she has the
current AFIS code, the specialist must either:
(a) Use LAA procedures to issue pertinent
AFIS information, or
(b) Advise the pilot to return to the AFIS
frequency.
5. AFIS broadcasts may be suspended within
specified time periods. During these periods, the
AFIS must contain a brief statement that the AFIS is
suspended for the specified time and pilots should
contact the FSS for LAA.
PHRASEOLOGY-
(Airport name) FLIGHT INFORMATION BROADCASTS
ARE SUSPENDED UNTIL (time). CONTACT (facility
name) RADIO ON (frequency) FOR AIRPORT
INFORMATION.
6. Parttime and seasonal facilities must record
a message with the appropriate frequency and facility
contact information as well as known information
regarding resumption of LAA.
PHRASEOLOGY-
(Name of FSS) HOURS OF OPERATION ARE (time)
LOCAL TIME TO (time) LOCAL TIME. THE COMMON
TRAFFIC ADVISORY FREQUENCY IS (frequency).
PILOT CONTROLLED LIGHTING IS AVAILABLE ON
(frequency). FOR ADDITIONAL INFORMATION
CONTACT (name of FSS) ON (frequency).
(Name of FSS) IS CLOSED FOR THE WINTER SEASON.
THE COMMON TRAFFIC ADVISORY FREQUENCY IS
(frequency). PILOT CONTROLLED LIGHTING IS
AVAILABLE ON (frequency). FOR ADDITIONAL
INFORMATION CONTACT (name of FSS) ON
(frequency).
7. Use the following format and include the
following in AFIS broadcast as appropriate:
(a) (Airport/facility name) airport
information.
(b) Phonetic alphabet designator.
(c) Special routing procedures in effect (when
appropriate for the Ketchikan (KTN) area).
(d) Time of the AFIS preparation (UTC)
followed by the word, “ZULU.”
(e) Include the current weather observation
and other pertinent remarks. The ceiling/sky
conditions, visibility, and obstruction to vision maybe omitted
if the ceiling is above 5,000 and the visibility is more
than 5 miles.
EXAMPLE-
“The weather is better than five thousand and five.”
(f) Favored runway and additional local
information, as required.
(g) NOTAMs concerning local NAVAIDs and
field conditions pertinent to flight.
EXAMPLE-
“Notice to Airmen, Iliamna NDB out of service.”
“Transcribed weather broadcast out of service.”
(h) Runway braking action or friction reports
when provided. Include the time of the report and a
word describing the cause of the runway friction
problem.
PHRASEOLOGY-
RUNWAY (number) MU (first value, second value, third
value) AT (time), (cause).
REFERENCE-
FAAO JO 7110.10, Para 443, Airport Advisory/RAIS Elements and
Phraseology.
(i) Lowlevel wind shear (LLWS) advisory,
including those contained in the terminal aerodrome
forecast (TAF) and in PIREPs. (Include PIREP
information at least 20 minutes following the report).
EXAMPLE-
“Low level wind shear is forecast.”
(j) Unauthorized Laser Illumination Events.
When a laser event is reported, include reported
unauthorized laser illumination events on the AFIS
broadcast for one hour following the last report.
Include the time, location, altitude, color, and
direction of the laser as reported by the pilot.
PHRASEOLOGY-
UNAUTHORIZED LASER ILLUMINATION EVENT,
(UTC time), (location), (altitude), (color), (direction).
EXAMPLE-
“Unauthorized laser illumination event at zero one zero
zero Zulu, eightmile final runway one eight at three
thousand feet, green laser from the southwest.”
(k) ManPortable Air Defense Systems
(MANPADS) alert and advisory. Specify the nature
and location of threat or incident, whether reported or
observed and by whom, time (if known), and
notification to pilots to advise ATC if they need to
divert.
PHRASEOLOGY-
MANPADS ALERT. EXERCISE EXTREME CAUTION.
MANPADS THREAT/ATTACK/POSTEVENT ACTIVITY
OBSERVED/REPORTED BY (reporting agency)
(location) AT (time, if known). (When transmitting to an
individual aircraft) ADVISE ON INITIAL CONTACT IF
YOU WANT TO DIVERT.
EXAMPLE-
“MANPADS alert. Exercise extreme caution. MANPADS
threat reported by TSA, Anchorage area. Advise on initial
contact if you want to divert.”
“MANPADS alert. Exercise extreme caution. MANPADS
attack observed by flight service station onehalf mile
northwest of airfield at onetwofivezero Zulu. Advise on
initial contact if you want to divert.”
NOTE-
1. Upon receiving or observing an unauthorized
MANPADS alert/advisory, contact the Alaska Flight
Service Information Area Group(AFSIAG) through the
Alaskan Region Regional Operations Center (ROC).
2. Continue broadcasting the MANPADS alert/advisory
until advised by national headquarters the threat is no
longer present. Coordination may be through the AFSIAG
or the Alaskan ROC.

(m) Local frequency advisory.
PHRASEOLOGY-
CONTACT (facility name) RADIO ON (frequency) FOR
TRAFFIC ADVISORIES.
(n) Instructions for the pilot to acknowledge
receipt of the AFIS message on initial contact.
