Civil Aviation Safety Regulation Part 175

Civil Aviation Safety Regulation Part 175 (Part 175) under the Civil Aviation Act 1988 came into effect on 5 March 2015. This regulation establishes standards and requirements for the quality and integrity of data and information used in air navigation. Specifically, information published in the Aeronautical Information Publication (AIP), on aeronautical charts and contained within aeronautical navigation databases. This is in compliance with the international Standards and Recommended Practices in Annex 4 – Aeronautical Charts, and Annex 15 – Aeronautical Information Services to the Chicago Convention. Under Part 175.E, Airservices may request information about an object or structure anywhere in Australia to confirm ownership, geographic location, dimensions and whether the structure or object is marked or lit. This data will be used to support Airservices Aeronautical Information Management (AIM) function, including use in aeronautical navigation databases and on aeronautical charts. Airservices is authorised to request data from a Part 175.E Data Supplier who own, control or operate objects and structures, such as:

  • buildings
  • bridges
  • cranes (permanent or temporary)
  • dams
  • electrical systems
  • fences
  • general utility
  • light houses
  • factories
  • poles (light poles, flag poles, telephone poles)
  • rigs (oil or gas)
  • signs
  • spires/steeples
  • industrial stacks
  • tanks (water, fuel)
  • towers
  • trees
  • vegetation
  • wind turbines and wind monitoring towers

Part 175.E Data Suppliers include Commonwealth, State, Territory or local government authorities. CASR175 has been developed to meet the dramatic changes in air navigation that has occurred with the advancement of computer and satellite navigation systems.  By collecting and supplying data with improved quality, stakeholders will be minimising the risk of corrupt, erroneous, late or missing data affecting the safety of air navigation in Australian airspace.


Airservices contact aerodromes, data providers and data originators to provide data in accordance with the data product specification (DPS) as required by CASR Part 175.
