Approval — means of providing surface wind information
Exemption — provision of a wind direction indicator
1          Duration
          This instrument:
(a)   commences on the day of registration; and
(b)   expires at the end of 30 November 2016, as if it had been repealed by another instrument.
2          Application
          This instrument applies to the operator (the aerodrome operator) of a certified aerodrome or a registered aerodrome (the aerodrome).
3          Approval
          I approve a wind direction indicator as a means of providing surface wind information to the pilot of an aircraft approaching a runway at the aerodrome in the following circumstances:
(a)   the runway is used in non-precision approach operations; and
(b)   no wind direction indicator is near the end of the runway at which instrument non-precision approach operations can be conducted; and
(c)   the wind direction indicator is installed and maintained in accordance with regulation 139.180 of CASR 1998; and
(d)   the automatic weather observing system (AWOS) or the weather information broadcast unit at the aerodrome is unserviceable; and
(e)   there is no approved observer who has a communication link with pilots through which timely information about surface wind can be clearly passed to pilots; and
(f)    the pilot is performing a circling approach to the runway; and
(g)   the pilot is able to observe the wind direction indicator before the final approach leg.
4          Exemptions
(1)     The aerodrome operator of a certified aerodrome is exempt from compliance with subregulation 139.185 (1) of CASR 1998.
(2)     The aerodrome operator of a registered aerodrome is exempt from compliance with Subpart 139.C of CASR 1998 to the extent that that Subpart requires the aerodrome operator to ensure that there is a wind direction indicator near the end or ends of a runway at which instrument non-precision approach operations can be conducted.
5          Conditions
          The exemptions in section 4 are subject to the conditions set out in Schedule 1.
Schedule 1          Conditions
        1     An AWOS must be installed at the aerodrome that:
(a)   is compatible with the Bureau of Meteorology’s weather observing system; and
(b)   provides surface wind information through an aerodrome weather information broadcast that is available to the pilots of aircraft approaching the runway.
      2     The aerodrome operator must ensure that:
(a)   the AWOS continues to operate in broadcast mode; and
(b)   the AWOS is maintained in accordance with the manufacturer’s instructions; and
(c)   the serviceability of the AWOS is monitored during each aerodrome serviceability inspection by the reporting officer of the aerodrome; and
(d)   the aerodrome manual for the aerodrome includes procedures to tell aerodrome users if there is a fault in the AWOS.
        3     If the AWOS or the weather information broadcast unit is unserviceable, the aerodrome operator must ensure that:
(a)   a NOTAM to that effect is issued; and
(b)   either:
             (i)  surface wind information is passed to pilots of aircraft approaching the runway by an approved observer who has a communication link with pilots through which timely information about surface wind can be clearly passed to pilots; or
            (ii)  a NOTAM is issued notifying pilots that:
(A)  the straight-in instrument approach procedure minima are not available; and
(B)   a circling approach is only available if the pilot is able to observe the aerodrome’s wind direction indicator before the final approach leg; and
(c)   the AWOS or unit is repaired as soon as reasonably possible.
