a buffer zone or instrument enclosure to the provider of the meteorological facilities within the instrument enclosure for assessment of whether the development would adversely affect the operation of the facilities.

Note   The buffer zones are described in section 19.18.

       (3) Herbicides and weed sprays must not be used in the vicinity of an instrument enclosure if this would result in the natural vegetation within the enclosure being exposed to the herbicide or spray.

       (4) For the buffer zone and the instrument enclosure, concrete or asphalt walkways:

(a) may be installed where the surface is likely to be rendered impassable or unsafe in wet conditions; and

(b) if installed, must be:

 (i) no wider than 0.5 m; and

 (ii) kept to a minimum consistent with reasonable accessibility to the instrument area.

       (5) The instrument enclosure must not be artificially watered by a source located outside the enclosure.

19.18 Siting requirements for meteorological facilities

Note   CASA recommends that for new and existing facilities, this section should be considered with the engineering, technical and instruction manuals associated with the required function and protection of the meteorological facility.

      1.          This section applies only in relation to the siting of meteorological facilities within an aerodrome boundary by the MET service provider as authorised under the regulations.

       (2) The site of a standard instrument enclosure within an aerodrome boundary must:

(a) be at least a 16 m by 16 m square enclosure (instrument enclosure) in the middle of a 30 m by 30 m square buffer zone (buffer zone) aligned in the True North – South direction; and

(b) take account of the exposure requirements of the most sensitive instrument to be installed in the instrument enclosure and the purpose of the installation, as advised by the MET service provider.

       (3) The instrument enclosure must be as follows:

(a) level;

(b) clearly defined;

(c) as densely covered with the natural vegetation typical of the surrounding area as is the surrounding area itself;

(d) maintained to a height of no more than 50 mm.

       (4) The instrument enclosure must not be artificially watered.

       (5) The outdoor instruments installed inside the instrument enclosure must be on a level piece of ground:

(a) whose surface is covered with short grass or is a surface representative of the locality; and

(b) surrounded by open fencing or palings to exclude unauthorised persons.

       (6) The instrument enclosure area must not be top-dressed with any material that is inconsistent with the surrounding surface type.

       (7) The buffer zone around an instrument enclosure must:

(a) be covered by the natural vegetation or ground cover of the region; and

(b) have the vegetation or ground cover maintained to a height of approximately 0.5 m.
