ATIS CONTENT
Identify each message by a phonetic alphabet letter code word at the beginning and at the end of
each message. Begin with ALPHA and continue through ZULU without regard to the beginning of a
new day. If a broadcast is interrupted for more than 12 hours, the first message after the broadcast
resumes should be coded ALPHA.
a. Make a recording when any of the following occur:
(1) A new official weather report is received, regardless of whether or not there is a change
of values.
(2) Anytime reports are received that show braking action is worse than now reported in the
ATIS broadcast or has improved to a point where it no longer needs to be reported.
(3) There is a change in pertinent data, such as change of runway in use, a different type of
approach in use, new or canceled NOTAMs, or publication of significant meteorological information
PIREPs.
b. Include first in the ATIS broadcast, the name of the terminal facility, a phonetic code
identifier, and the time and type of weather sequence. Second, include the sky conditions and ceiling if
below 5,000 feet, the visibility if less than 5 miles, and any obstructions to vision.1 Third, include
temperature, dew point (if available), wind direction and velocity, and altimeter. Fourth, include
pertinent remarks, instrument approach, and runway in use. Fifth, include braking action, when
applicable.2 Sixth, include information the pilot should give to the controller on initial contact, such as
"advise the controller on initial contact that you have information ALPHA."
1
If the weather is at or above a ceiling or sky condition of 5,000 feet and the visibility is 5 miles
or more, inclusion of the ceiling or sky condition, visibility, and obstructions to vision in the ATIS
message is optional. A remark such as "the weather is better than 5,000 and five" may be made instead
these conditions.
2
When weather conditions are conducive to deteriorating or rapidly changing runway braking
action, include on the ATIS broadcast the statement "Braking action advisories are in effect."
