Strategic airports and aviation facilities

Practice note 7—building restricted areas for aviation facilities diagrams This information is provided by Airservices Australia and provides details of the building restricted areas for each type of protected aviation facility and the development constraints within these areas.

Appendix 1 (Guideline: Strategic airports and aviation facilities) requires local governments to map in an overlay the relevant building restricted area and development constraints associated with the aviation facility sited in the local government area.

Future changes in technology and implementation of International Civil Aviation Organisation standards across Australia could result in changes to the type, number and constraints for the protection of aviation facilities. Therefore, up-to-date details of aviation facilities should be obtained from Airservices Australia.

Mapping the building restricted areas in planning schemes

The information below provides a comprehensive list of development constraints including some that will be outside the scope of the planning scheme and will be controlled by Airservices Australia or airport managers as landowners around each aviation facility.

The planning scheme need only depict those parts of the building restricted areas that lie outside the ownership/control of Airservices Australia or the airport owner. Those parts need to be depicted at a scale that adequately shows the detail of the ‘sub-areas’ (i.e. the areas shown as A, B, C etc. on the diagrams below). The information is likely to be best depicted in an overlay and the mapped area should also be accompanied by the relevant parts of the cross-section for the particular facility as shown below.

Automatic dependent surveillance-broadcast (ADS-B) and WAM

Building restricted area

A1—Critical zone: within a 100 metre radius from the antenna base, area A1. The critical zone is defined as a cylindrical volume extending down to one metre below the antenna base, area A1

A2—Sensitive zone: the concentric area (from the antenna) between 100–1 500 metres, area A2. The sensitive zone is defined as a one degree (1°) gradient volume A2.

B—The zones depicted as B and C are unrestricted.

C—The zones depicted as B and C are unrestricted.

Non-directional beacon (NDB)

  Building restricted area

(1) All development proposals within a 60 metre radius of the NDB antenna and development proposals between 60–300 metre radius from the centre of the NDB antenna that exceed an elevation angle of 5° from ground level at the centre of the NDB antenna, require assessment by Airservices Australia.

(2) Unrestricted.

Distance measuring equipment (DME)

  Building restricted area

If the DME antenna is co-located with a Very High Frequency Omni-directional Range (VOR), Localiser or Glidepath facility, the building restricted area of the respective co-located facility should be used as the DME building restricted area. Otherwise the following restrictions apply:

(3) All development proposals within 100 metres of the DME antenna which exceed a horizontal plane located 4 metres below the centre of the DME antenna and development proposals between 100–1500 metres from the DME antenna that exceed an angle of elevation of 2.0°, measured from the above horizontal plane beneath the DME antenna, require assessment by Airservices Australia.

(4) Unrestricted.

Instrument landing system (ILS) Glidepath

 

  Building restricted area The building restricted area is defined as an area in which static structures, such as airport hangars, large buildings, perimeter fences, trees etc, may affect the ILS signal-in-space and is required to be assessed by Airservices Australia.

The building restricted area is defined to be greater than 0.5° elevation longitudinally and 2° elevation laterally from the edges of the vehicle critical area, measured from a base level which is equal to the ground level at the Glidepath antenna tower.

The building restricted area includes an area 40 metres either side of the extended Glidepath centreline to a distance of 50 metres behind the Glidepath tower.

ILS localiser

  

  Building restricted area

The building restricted area is defined as an area in which static structures, such as airport hangars, large buildings, perimeter fences, trees etc, may affect the ILS signal-in-space and is required to be assessed by Airservices Australia.

The building restricted area is defined to be greater than 0.5° elevation longitudinally and 2° elevation laterally from the edges of the vehicle critical area, measured from a base level which is equal to the ground level at the localiser antenna.

The building restricted area includes an area 45 metres either side of the extended runway centreline to a distance of 50 metres behind the localiser antenna.

All buildings within 1000 meters of the runway centreline which have a vertical wall facing the runway that exceeds 2000 square meters in area and a height more than 20 metres above the localiser ground level, such as hangars and office blocks, are to be assessed by Airservices Australia.

HF communication facilities

 

  

Building restricted area—restricted area

To ensure that the HF antenna performance is not compromised, substantial structures and developments are generally prohibited within the restricted area, which is above the plane depicted in the development constraints or within 6 kilometres of the HF receive antenna.

All developments within the HF restricted area shall be submitted to Airservices Australia for assessment.

 

Building restricted area—area of interest

All developments within the HF Area of Interest should be submitted to Airservices Australia for assessment.

11

VHF communication facilities

In general, Airservices Australia VHF sites are ‘collocated receive and transmit’ sites. The propagation distance for VHF signals is essentially governed by line of sight from the antenna at the transmitting site. Generally, the antenna is mounted so that it is clear of local obstructions such as trees, buildings and hills. Tower heights usually vary from 3-100 metres, or more in some cases.

  

Building restricted area—restricted area

Substantial structures are generally prohibited within the restricted area. All developments within the VHF restricted area shall be submitted to Airservices Australia for assessment.

  

Building restricted area—area of interest

Two kilometres in radius, all developments within the VHF Area of Interest should be submitted to Airservices Australia for assessment.
