CASR Part 175 – Aeronautical information services

The role and importance of aeronautical information and aeronautical data changed significantly with the implementation of area navigation (RNAV), required navigation performance (RNP), airborne computer based navigation systems and data link systems. Corrupt or erroneous aeronautical information and aeronautical data can potentially affect the safety of air navigation.

ICAO requires Contracting States to the Chicago Convention to provide an AIS which publishes aeronautical information and charts in an Aeronautical Information Publication (AIP). CAR 233 (1)(h) requires pilots to carry aeronautical maps, charts, aeronautical information and instructions published in the AIP relevant to the route being flown and any alternate route that may be flown. Additionally, pilots are permitted to carry aeronautical maps, charts, aeronautical information and instructions if they are published by holders of an instrument of approval issued under CAR 233 (1)(h).

These instrument of approval holders will be referred to as data service providers in the new regulations and there will be a requirement for data service providers to demonstrate that their published data conforms with the data published in the AIP.

CASR Part 175 will create data publication standards for the AIS provider and for data service providers. Part 175 will require all service providers to demonstrate that data integrity has been maintained throughout all their data processes. Part 175 will provide Australia with a means of demonstrating compliance with the ICAO Standards and Recommended Practices of Annex 15 (Aeronautical Information Services) and Annex 4 (Aeronautical Charts). Most importantly, Part 175 will provide the aviation industry with the necessary assurance levels with regard to the integrity of published aeronautical information and aeronautical data.

Who Part 175 affects

  • Airservices Australia;
  • Publishers of aeronautical information products;
  • Originators of aeronautical information;
  • Geoscience Australia;
  • Aerodrome operators;
  • Airlines;
  • Aircraft operators;
  • Pilots; and
  • Consumers of aeronautical information products.
