Executive Summary
AECOM were engaged by Verve Energy to deliver an Aviation Impact Statement for a proposed wind turbine farm
at Warradarge, Shire of Coorow, Western Australia.
This report examines and assesses the impact of the tall wind turbine structures as potential obstacles to aviation
operations and procedures.
The report locates aerodromes within 30Nm (55.56km) radius of the wind farm perimeter, assesses any potential
intrusion to Object Limitation Surfaces (OLS) and any impact to aerodrome instrument approach and landing
procedures.
Air routes and airspaces are examined to determine whether there is an impact on Lowest Safe Altitudes (LSALT)
and potential conflicts with air routes located near or over the proposed wind farm.
The statement finds that the wind farm is located in an area of farming communities and minor mining at
Eneabba. Aerodromes are small and unregistered within the vicinity of the proposed wind farm with most low
airspace aviation related to the farming communities, mining and light general aviation.
The site of the proposed wind farm is on a prominent hill, and minor adjustments to aviation charts will potentially
be required to highlight the proposed wind farm as the turbines need to be stated as obstacles when they are
above 110m in height.
Published air routes, both high and low domestic routes, are 6Nm (11km) or greater distance from the proposed
wind farm.
No Airservices Australia surveillance radar is located within line of sight of the proposed wind farm. The nearest
primary radar location is at Mt Kalamunda, Perth.
AECOM’s recommendation is that the findings of this study are passed onto ASA and the Civil Aviation Safety
Authority (CASA) to enable them to assess the impact before commencement of construction of the proposed
wind farm at Warradarge.

1.0 Introduction
Verve Energy has commissioned AECOM to complete an Aviation Impact Statement (AIS) for the proposed
Warradarge Wind Farm. Guidelines to manage the risk of aviation safety from wind turbine installations are
currently under development by the National Airports Safeguarding Advisory Group (NASAG). In the interim, this
AIS has been written to meet the criteria set out by Airservices Australia (ASA) as attached in Appendix A.
The proposed Warradarge wind farm will consist of 100 turbines, up to 152m in height. The farm is to be located
120Nm (222km) north of Perth on a hill between Rose Thompson Road and Garibaldi Willis Road in the Shire of
Coorow, Western Australia.
1.1 AECOM
AECOM are an aviation consultant with experience in the assessment and examination of obstacles for
aerodromes and general airspace. Recent projects in the field include:
- Blackstone Power Station Plume Rise Assessment – A proposed plume was assessed for impact to RAAF
Amberley Airbase’s controlled airspace.
- Gladstone Air Space Risk Assessment – Assessment of new gas fired power station plume
- Albany Airport Master Plan – assessment of the Object Limitation Surfaces at Albany airport for future
terminal and apron developments and runway extensions
1.2 Project Inputs and Assumptions
Verve Energy provided AECOM with a spread sheet of data for the proposed wind farm towers, which included:
- latitudes / longitudes
- eastings / northings
- height of ground level at the base of each tower
The latitudes/longitudes are WGS84 Datum; eastings / northings are GDA 1994 MGA zone 50; and the heights of
ground level at the bases provided as metres above mean sea level.
A drawing was also provided showing the arrangement of the wind farm turbines. To allow for Verve Energy to
adjust and finalise the permanent position of the turbines within the proposed wind farm, the boundary of the wind
farm site has been used for this AIS. Verve Energy has also provided greatest possible height for the base of a
turbine as being 1154FT (352m) AMSL. The site boundary, at this maximum possible turbine base height, has
been used as the design obstacle envelope to be assessed for the AIS.
No assessment has been made of the aviation impact during construction of the wind farm. Appropriate
authorities will need to be notified on construction methods adopted (especially crane operations). CASA/ASA
should be specifically informed as the proposed wind farm is on a hill with highest spot height (1142FT, 348.1m)
within a 25Nm (46.3km) radius on Chart WAC 3351 (Perth). At the discretion of appropriate authorities NOTAMs
released could be made to cover construction as well as the completed proposed wind farm.
Assessments or statements for the purpose of supplying information to Royal Australian Air Force (RAAF)
Aeronautical Information Services is outside of the scope of this report. However this AIS has found no military
airfield within 30km (16.2Nm) of the proposed wind farm. The RAAF Aeronautical Information Service’s database
of tall structures does require top measurements of tall structures 45m or more above ground level as set out in
CASA Advisory Circular 139-08(0) which can be found in Appendix B
Any required conversions of units have been completed using the conversion tables and factors set out in the
Aeronautical Information Package (AIP).
1.3 AIS Criteria and Document Structure
This AIS has been written to meet the criteria set out in the Airservices Australia Aviation Assessments for Wind
Farm Developments. This letter has been provided by Verve Energy and is included in Appendix A. The criteria
are set for regulatory and safety procedures to protect aviation operations.
The main requirements of ASA’s AIS Criteria are as follows:
AECOM
Warradarge Wind Farm
Aviation Impact Statement
26 March 2012
3
1) Determine the location (in WGS 84 to 0.1 second of arc or better) and Elevations (AMSL to 0.3 meters) of
each potential obstacle. This is a statutory requirement of Civil Aviation Safety Regulations 1998
(CASR1998) Part 139.365 that the owner (or proponents) of structures greater than 110m must inform
CASA/ASA.
a) This information has been provided in table form in Appendix B
b) An overlayed topographical base drawing “60248070-AV-DRG-001_A” has been included in Appendix
C of this AIS. An electronic version (Microstation V8i) has also been provided to Verve Energy.
2) The Aerodromes Section has three requirements:
a) Specify all registered/certified aerodromes that are located within 30Nm (55.56km) from any obstacle
referred to in 1) above.
b) Nominate all instrument approach and landing procedures at these aerodromes.
c) Confirmation that the obstacles do not penetrate Annex 14 or OLS for any aerodrome. If an obstacle
does penetrate, specify the extent.
This section is for the safe operation of aerodromes to CASR 1998 Part 139 and to locate potential conflicts
with Airports (Protection of Airspace) Regulations 1996. This is set out in Section 2 of this AIS.
3) Airspaces and Air Routes need to be considered where a proposed wind farm is to be located outside of the
operation limits of an aerodrome’s Procedures for Air Navigation Systems Operations and Obstacle
Limitation Surfaces (OLS). There are three elements to produce and/or assess:
a) Nominate air routes published in En Route Chart (High and Low) (ERC-L & ERC-H) which are located
near/over any obstacle referred to in 1) above.
b) Specify two waypoint names located on the routes which are located before and after the obstacles.
c) Airspace classification – A, B, C, D, E, G etc. where the obstacles are located.
CASR 1998 Part 139.365 directly impacts the declaration and calculation of obstacles and this has been
assessed in Section 3 of this AIS.
4) Navigation and Radar impact assessment is required to determine any potential for any degradation due to
interference potentially caused by the proposed wind farm. This is especially the case where there are two
or more turbines.

2.0 Aerodromes
This section presents the investigation into the location, CASA/AIP registration status, DAP and other applicable
information for aerodromes located within 30Nm (55.56km) of the proposed wind farm. The following process has
been followed:
- The location of the proposed wind farm has been identified and a zone within 30Nm (55.56km) searched for
registered / certified aerodromes
- Where applicable, the aerodromes were checked for DAP 130 information and registration levels on AIP
websites
- The Shires of Three Springs, Dongarra, Carnamah, Coorow, Dandaragan and Moora were contacted to
identify the aerodromes found previously and provide information on any other known aerodromes within the
shire boundaries
- All the information gathered was added to a drawing and the aerodromes assessed for any potential impact
following construction of the wind farm
The main findings for the aerodromes within 30Nm (55.56km) of the proposed wind farm were:
- No CASA registered or certified aerodromes are found
- No aerodromes have DAP or any specific AIP DAP130 recorded information
- Jurien Bay is shown as an unregistered aerodrome in the En-Route Supplement – Australia (ERSA) facilities
(FAC) document. It has also the following waypoint information: JURIEN BAY WA YJNB 30 18 12S 115 03
19E (source Section 19 AIP)
- The Jurien Bay VOR is located at Jurien Bay Aerodrome and is the only Navigational Aid System identified
within the 30Nm (55.56km) range of the proposed wind farm
- The light aircraft gravel strip at Judeen Farm, approximately 3100m North East of the nearest turbine
location 28, has been recognised as the nearest aerodrome. Its runway length is between 700-800m (as
scaled off Google aerial photography) and has been confirmed by Dave Haddon of Shire of Coorow
Regulatory Services as being a farmer’s cleared gravel strip. CASA Manual of Standards 139 (MOS139) and
the ICAO Annex 14 state that the combined inner horizontal and conical OLS’ for a Code 1 airport with a
runway length of no more than 800m shall extend to 2700m. This is less than the 3100m from turbine
location 28.
- The next nearest airport, Eneabba, is located approximately 30km (16.2Nm) from the proposed wind farm, is
unregistered and is unlikely to have an OLS that would extend more than 15km (8.1km).

3.2 Air Space
For the assessment on impact to local airspace the wind farm was located on ERC-L8 chart. The Wind farm is
located in grid square S29° E115°. This grid is shown on AIP ERC-L8 as being a Class G airspace (unshaded)
and has a grid lowest safe altitude of 2800FT (853.4m).
ERC-H4 and H3 show the wind farm located in grid square S28° E114° with a LSALT of 2900FT (884m).
From the charts Class E mid-level airspace starts at a flight level of 18,000FT and high level Class A airspace
starts at flight level 24,500FT in the vicinity of the wind farm.
Class G airspace is uncontrolled and accounts for the majority of Australian Airspace. Separation service of
aircraft is not provided by ASA within this airspace however flight information service is provided to IFR Aircraft
and, upon request, for VFR Aircraft at an altitude where there is potential for radar coverage. Aircraft speeds are
limited to 250 knots below 10,000fFT AMSL and ‘no-radio’ flights may be conducted below 5,000FT AMSL.

The highest wind turbine has a height of 1646FT (501.6m) AMSL. As set out in the AIP section GEN 3.2, 2.21
(http://www.airservicesaustralia.com/aip/current/aip/general.pdf) the LSALT is calculated by adding 1000FT
(304.8m) to the highest obstacle. This amounts to a LSALT of 2640FT (804.6m) for the obstacles at the proposed
wind farm.
As a worst case, the highest point on the hill within the proposed wind farm boundary is 352m (as provided by
Verve Energy). A 152m tall turbine on this high point will equate to a maximum potential obstacle height of
1654FT (504m) or a LSALT of 2654FT (808.9m). Both the current proposed highest wind turbine and maximum
potential height of a wind turbine within the proposed wind farm are lower than the currently published LSALT of
2800FT (853.4m) for grid square S29° E115°.
The proposed wind farm may need to be added to the World Aeronautical Chart (WAC) (3351) Perth as an
obstacle. The wind farm is likely to become the highest obstacle within the S29°30’ E115°0’ half degree grid
square as it to be located on the hill which is currently shown as the highest obstacle at 1142FT (348.1m).
The most likely use of the airspace below the LSALT is aviation involved in the agricultural industry operating light
aircraft to Visual Flight Rules (VFR). No special use of airspace was located on any chart within the vicinity of the
proposed wind farm including sporting and miscellaneous uses.

4.0 Navigation/Radar
The nearest radar location to the proposed wind farm is located 120Nm (222km) away at Mount Kalamunda in the
hills east of Perth Airport. Whilst the range of this surveillance equipment is very extensive, the curvature of the
earth means the wind farm is located out of line of sight and should have little or no effect on the existing radar
coverage. Appendix C shows calculations for determining the Radar Horizon distance required for the radar and
proposed wind farm to be in line of sight.
Further assessment for dead zones, false targets etc. have been discusses with Joe Doherty of ASA and deemed
to be unnecessary.
Assessment of other navigational aids such as the VOR at Jurien Bay is unlikely to raise any issues due to the
lack of air routes that coincide with the proposed location of the wind farm. ICAO uses a 1:50 surface to determine
potential impact of an obstacle. The proposed wind farm site does not interfere with this surface.

To Whom It May Concern Airservices Aviation Assessments for Wind Farm Developments
Guidelines to manage the risk to aviation safety from wind turbine installations (Wind Farms/Wind Monitoring Towers) are under development by the National Airports Safeguarding Advisory Group (NASAG). NASAG is comprised of high-level Commonwealth, State and Territory transport and planning officials and has been formed to develop a national land use planning regime to apply near airports and under flight paths. The wind farm guidelines will provide information to proponents and planning authorities to help identify any potential safety risks posed by wind turbine and wind monitoring installations from an aviation perspective. Potential safety risks include (but are not limited to) impacts on flight procedures and aviation communications, navigation and surveillance (CNS) facilities which require assessment by Airservices. To facilitate these assessments all wind farm proposals submitted to Airservices must include an Aviation Impact Statement (AIS) prepared by an aeronautical consultant in accordance with the AIS criteria set out below. AIS must be undertaken by an aeronautical consultant with suitable knowledge and capabilities to provide a reliable and comprehensive report. All data is to be supplied in electronic form. If you are not familiar with any aeronautical consultants, you may wish to view the list on the Civil Aviation Safety Authority (CASA) website:
http://www.casa.gov.au/scripts/nc.dll?WCMS:STANDARD::pc=PC_90412
AIS Criteria
The AIS must provide a detailed analysis covering, as a minimum:
Airspace Procedures:
1. Obstacles
Co-ordinates in WGS 84 (to 0.1 second of arc or better)
Elevations AMSL (to 0.3 metres)
2. Drawings
Overlayed on topographical base not less that 1:250,000. Details of datum and level of charting accuracy to be noted.
Electronic format compatible with Microstation version 8i.
3. Aerodromes
Specify all registered/certified aerodromes that are located within 30nm (55.56km) from any obstacle referred to in (1) above.
Nominate all instrument approach and landing procedures at these aerodromes.
Confirmation that the obstacles do not penetrate Annex 14 or OLS for any aerodrome. If an obstacle does penetrate, specify the extent.
4. Air Routes
Nominate air routes published in ERC-L & ERC-H which are located near/over any obstacle referred to in (1) above.
Specify two waypoint names located on the routes which are located before and after the obstacles.
5. Airspace
Airspace classification – A, B, C, D, E, G etc where the obstacles are located.
Navigation/Radar:
1. Detect the presence of dead zones
2. False target analysis
3. Target positional accuracy
4. Probability of detection
5. Radar coverage implications
6. We would expect the analysis to follow the guidelines outlined in the EUROCONTROL Guidelines on How to Assess the Potential Impact of Wind Turbines on Surveillance Sensors.
http://www.eurocontrol.int/surveillance/public/standard_page/sur_WTTF.html
Airservices Review of AIS
Airservices will review the quality and completeness of an AIS and will undertake limited modelling and analysis to confirm the findings and recommendations of the report. Provided the AIS is of sound quality and is complete in accordance with the above criteria, there will be no charge for the review or limited modelling and analysis. If the AIS is not of sound quality or is not complete in accordance with the above criteria, no modelling or analysis will be undertaken. Airservices will advise the proponent that the AIS does not meet the requirements and that the proposal cannot be assessed by Airservices. If Airservices review of an AIS confirms impacts identified in the report (or identifies additional impacts), Airservices will advise the proponent of the impacts and the required mitigating actions (where mitigation is feasible). The proponent will also be advised that there will be charges for any mitigation actions to be undertaken by Airservices.
These charges may be advised at the time but it is likely that a detailed quote will be needed and this will only be provided on request from the proponent. Please contact Joe Doherty, Airport Development Manager (02) 62685101 or alternatively [email protected] if you have any questions.
