Zone A If development is located: within 100 metres of the Very High Frequency antenna; or between 100-2000 metres from the centre of the Very High Frequency antenna and the development will cross the zone boundary (defined as an elevation angle of 2° starting at 10 metres above ground level). All applications must be referred to Airservices Australia for assessment. Zone B If development is located between metres from the centre of the Very High Frequency antenna and the development will not cross the zone boundary. No requirements. Airservices Australia should be advised of proposals for large obstructions. Area of interest If development is located between metres from the Very High Frequency antenna. No requirements. Airservices Australia should be advised of proposals for large obstructions.
Zone A If development is located: within 100 metres of the Distance Measuring Equipment antenna and above a horizontal plane located 4 metres below the centre of the Distance Measuring Equipment antenna; or between 100–1500 metres from the Distance Measuring Equipment antenna and the development will cross the zone boundary (defined as an elevation angle of 2°, measured from the above horizontal plane beneath the Distance Measuring Equipment antenna). All applications must be referred to Airservices Australia for assessment. Zone B If development is located between 100-1500 metres from the centre of the Distance Measuring Equipment antenna and the development will not cross the zone boundary. No requirements. General guidance: high voltage overhead powerlines, 33kV or greater, which cross the zone boundary should be at least 300 metres from the Distance Measuring Equipment antenna; if the Distance Measuring Equipment antenna is co-located with a Very High Frequency Omni-directional Range, Localizer or Glidepath facility, the building restricted area of the co-located facility should be used as the Distance Measuring Equipment building restricted area. Very High Frequency Omni-directional Range Very High Frequency Omni-directional Ranges are navigation aids used in non-precision approaches, aircraft holding patterns and airways routes. The Course Deviation Indicator on an aircraft calculates bearing to and from the VHF Omni-directional Range. There are two types of VHF Omni-directional Ranges, Doppler and Conventional, each of which can be mounted either on the ground or elevated. Conventional Very High Frequency Omni-directional Range Ground mounted Conventional Very High Frequency Omni-directional Range Building Restricted Area Location of development Action required
Building Restricted Area Description Action required Zone A If development is located: within 5 metres of the marker beacon antenna; or between 5-50 metres of the marker beacon antenna and the development will the zone boundary (defined as an elevation angle of 50° from ground level at the marker beacon antenna). All applications must be referred to Airservices Australia for assessment. Zone B If development is located between 5-50 metres of the marker beacon antenna and the development will not cross the zone boundary. No requirements. General guidance - within 5 metres of the marker beacon, grass and other vegetation should be less than 60cm tall. Glide Path Building Restricted Area Description Action required Zone A If development is located: within the area defined as greater than 0.5° elevation longitudinally and 2° elevation laterally from the edges of the vehicle critical area (runway) (measured from the ground level at the Glide Path Antenna Tower); and within 40 metres either side of the extended glide path centreline to a distance of 50 metres behind the Glide Path Antenna Tower. All applications must be referred to Airservices Australia for assessment. Zone B All other areas not described by Zone A. No requirements.
Zone A: Zone B: Primary and Secondary Surveillance Radar Building Restricted Area Description Action required Zone A If development is located: within 500 metres of the antenna; and above a horizontal plane located 4 metres below the base of the antenna. All applications must be referred to Airservices Australia for assessment. Zone B If development is located: within 4000 metres of the antenna; and the development will cross the zone boundary (defined as an elevation angle of 0.5° measured from 8 metres below the height of the radar antenna) All applications must be referred to Airservices Australia for assessment. Area of interest If development is located: within 15 km of the antenna; and the height of the development will cross the zone boundary (defined as an angle of elevation of 0.25° measured from the height of the antenna) All applications must be referred to Airservices Australia for assessment. General guidance: no temporary or permanent obstructions should infringe on Zone A or Zone B; any sharp discontinuity protruding into the area of interest such as single metal light towers, power pylons and city buildings, will impact on performance and should be avoided where possible.
