WIND.../...
WIND DIRECTION quoted as either:
a. SINGLE MEAN DIRECTION
b. TWO VALUES representing variation in wind direction will be given whenever;
(i) the extremes in wind direction vary by 60° or more, or
(ii) the variation is considered to be operationally significant (eg, the variation
is less than 60°, but the variation from the mean results is either a
downwind and/or significant cross-wind component on a nominated
runway)
a. VARIABLE will be used when the reporting of a mean wind direction is not possible,
such as:
(i) in light wind conditions (3KT or less) or
(ii) the wind is veering or backing by 180° or more (eg, passage of
thunderstorms, or localised wind effect).
WIND SPEED quoted as either:
a. CALM (less than 1KT, eg "WIND CALM")
b. SINGLE MAXIMUM VALUE whenever the extremes between minimum and
maximum are 10KT or less (eg, "WIND 250 DEGREES MAXIMUM 25 KNOTS")
c. TWO VALUES REPRESENTING MINIMUM AND MAXIMUM VALUES whenever the
extremes in wind vary by more than 10KT (eg,"WIND 250 DEGREES MINIMUM 15
KNOTS, MAXIMUM 28 KNOTS")
Note: When quoting a wind with variations in speed and direction, the above criteria
may be varied in order to indicate the true cross-wind and/or downwind.

Where threshold wind analysers are installed and the wind at the threshold of a duty
runway varies from that of the central wind analyser or the threshold wind on the
other duty runway by 10° or 5KT or more and the variation is anticipated to continue
for more than 15MIN , threshold winds may be broadcast on the ATIS; eg.
THRESHOLD WIND RUNWAY…
(number),…/…, RUNWAY…(number),…/…
QNH…
TEMPERATURE
CLOUD…
VISIBILITY…
When visibility is less than 2,000M, RVR will be reported when available.
PRESENT WEATHER… (as applicable; eg, showers in area)
or
CAVOK
EXPECT (type of instrument approach) [WITH RADAR VECTORING] (if applicable).
*ON FIRST CONTACT WITH… (eg GROUND, TOWER, APPROACH) NOTIFY RECEIPT OF
… (code letter of the ATIS/CATIS broadcast).
*This conclusion may not be transmitted when space is limiting.
At locations where CATIS is installed, a time check should be included in the
broadcast.
At locations where runway threshold wind analysers are installed, a tower controller
must provide a departing aircraft with the wind at the upwind area of the runway if it
varies from the ATIS broadcast by 10° or 5KT or more, and the variation is anticipated
to continue for more than 15MIN. Such information shall be passed by use of the
phrase “WIND AT UPWIND END…/…”

WIND SHEAR
When moderate, strong or severe wind sheer has been reported on the approach or
take-off paths, or has been forecast, the information will be included on the ATIS in
the following format, eg:
• WIND SHEAR WARNING - CESSNA 210 [(wake turbulence category) CATEGORY
AIRCRAFT (if military CATIS)] REPORTED MODERATE WIND SHEAR ON APPROACH
RUNWAY 34 AT THE TIME OF 0920, (plus, if available, wind shear advice issued by
MET, eg: FORECAST WIND AT 300 FEET ABOVE GROUND LEVEL 360 DEGREES 45
KNOTS); or
• PROBABLE VERTICAL WIND SHEAR FROM 0415 TO 0430- FORECAST WIND AT 200
FEET ABOVE GROUND LEVEL 110 DEGREES 50 KNOTS.
AERIS
The Automatic En Route Information Service continuously broadcasts routine
meteorological reports (METAR) from a network of VHF transmitters installed around
Australia.
The information broadcast on the individual transmitters caters primarily for the needs
of aircraft operating in control areas within VHF range of the facility.
The network frequencies and the operational information menus are contained in
ERSA GEN.
