Appendix A: Glossary of Aeronautical Terms and Abbreviations NSW DEPNNTMENT OF PLA¡.¡NING ¡ro E¡¡vIRoNiIENT Banxsrowu CBD Anen, NSW THEAMAIDJI GNOUP 1 Execunve Summmv The Ambidji Group Pty Ltd was tasked by the New South Wales Department of Planning and Environment (DPE) to prepare a Preliminary Aeronautical lmpact Assessment (AlA) to enable provision of advice and recommendations on suitable building heights within the Bankstown CBD area. The AIA concludes that: a The Prescribed Airspaces for Obstacle Limitation Surfaces (OLS) and the Procedures for Air Navigation Services - Aircraft Operations (PANS-OPS) surfaces for Sydney and Bankstown Airports extend over the Bankstown CBD area; a The limiting surfaces over the Bankstown CBD area are the lnner Horizontal Surface (lHS) OLS surface at 55 m AHD, and the Conical Surface (CS) rising to 72 m AHD at the north east boundary of the area; a These surfaces limit the height of any development including construction cranes in the Bankstown CBD area; Requests can be made to penetrate the IHS and CS, but these must be submitted to Bankstown Airport Limited, supported by an aeronautical safety case, and approved by the Civil Aviation Safety Authority (CASA), Airservices Australia (AsA) and industry stakeholders. Such requests are normally required to be made on a case-by-case basis and a "blanket" approval for an increased height over the entire CBD area is unlikely to be agreed, although it may be possible for selected areas of the CBD; a CASA may require obstruction lighting to be installed on approved buildings and cranes which exceed the OLS heights; a It will not be possible to penetrate the lowest PANS-OPS surface of 135.9 m AHD; a The safety of flights operating under the lnstrument Flight Rules (lFR) and Visual Flight Rules (VFR) which may fly over the CBD area will not be impacted; o The restricted areas for navigation aids and radar sensors will not be infringed; a Department of Defence installations and operations at Richmond and Holsworthy will not be impacted; and a lf there will be roof top plume rises exceeding 4.3 m/s a plume rise assessment will be conducted by CASA. lf the rise is less then no assessment will be required.

The area used for this assessment was based on an AutoCAD drawing "Bankstown_Typology_CAD.dwg" provided by the DPE on 1 May 2015. An image of this drawing is shown in Figure 2.1. ü [æ Figure 2.1 Bankstown CBD Area from the Bankstown _Typology_CAD drawing (Source: DPE) It was not possible to use the exact areas shown above, as streets shown on the image do not match those shown in the Prescribed Airspace charts published by Sydney Airport Corporation Limited (SACL) and Bankstown Airport Limited (BAL). However a compromise area was constructed and this area contains the boundaries shown in Figure 2.1. The Bankstown CBD area is located 13 km North West of the Sydney Airport Aerodrome Reference Point (ARP), and 3.43 km north east of the Bankstown Airport ARP. Figure 2.2 shows the boundaries of the CBD area in relation to Sydney and Bankstown Airports.

Mernooor-ocv The methodology employed for the preparation of this report primarily focuses on the consideration of the key elements of: . the Airports Act 1996 (Part 12, Protection of airspace around airports); . the Airports (Protection of Airspace) Regulations 1996; . CivilAviation (Building Control) Regulations 1988; . Civil Aviation Safety Regulations (CASR) Part 139 Manual of Standards (MOS), Chapter 7 Obstacle Restriction and Limitation and Chapter 11 Standards for Other Aerodrome Facilities; . Airservices Australia document Navigation Aid Building Restricted Areas and Siting Guidance AEI-7.1613 lssue 2; and o CASA Advisory Circular AC 139-5 (1) Plume Rise Assessments. The key elements of the report involve a preliminary assessment of: . the Obstacle Limitation Surfaces (OLS); The object of the OLS is to define a volume of airspace in proximity to the airport which should be kept free of obstacles that may endanger aircraft in visual operations, or during the visual stages of an instrument approach. The intention is not to restrict or prohibit all obstacles, but to ensure that either existing or potential obstacles are examined for their impact on aircraft operations and that their presence is properly taken into account. Since they are relevant to visual operations, it may sometimes be sufficient to ensure that the obstacle is conspicuous to pilots, and this may require that the obstacles be marked or lit. the Procedures for Air Navigation Services - Aircraft Operations (PANS OPS) Surfaces; PANS OPS surfaces detail essential areas and obstacle clearance requirements for the achievement of safe, regular instrument flight operations. The instrument flight procedures enable pilots to either descend from the high en-route environment of cruise type flight to establish visual contact with the landing runway, or climb from the runway NSW DEPNNT]üENT OF PLANNING I¡Io EI.¡vIRoNMENT Bmrxsrown GBD Ane+ NSW TH¡Amero¡r Gnoup after take-off to the en-route environment, with a prescribed safe margin above terrain and obstacles, by use of aircraft instruments and radio navigation aids or Global Positioning System (GPS) in conditions where the pilot cannot maintain visual contact with the terrain and obstacles due to inclement weather conditions. a the Standards for Siting and Clearance Areas for Airways Facilities on Airports; These Clearance Areas are published to ensure that any construction does not impact on the operation of the facilities by physícal obstruction or electronic interference of the signal propagation. a the requirement for a plume rise assessment by CASA. lf roof top plume rises exceed 4.3 mis, details need to be provided to CASA so that an assessment can be made as to the impact on the safety of aircraft operations. 4. Svouev ARpoRr PnescRteeD AtRspAcE ln accordance with the Airports Act 1996 (Part 12, Protection of airspace around airports), on March 20 2015 Sydney Airport Corporation limited (SACL) published revised Prescribed Airspace Charts for the airport. The Prescribed Airspace was declared by the Commonwealth Department of lnfrastructure and Regional Development. The charts for the OLS and PANS-OPS surfaces for the airport were examined in relation to the to the Bankstown CBD area to determine the maximum development heights (including construction cranes) to avoid penetration of the surfaces. lt should be noted that the heights on the charts are above the Australian Height Datum (AHD). There are no plans to extend the surfaces for this airport. 4.1 A¡nlvsrs oF SyDNEy Oesncle Llu¡ranon Sunrtces (OLS) Figure 4.1 shows the Bankstown CBD area (red) in relation to the Sydney OLS.
