Why was CASR Part 175 introduced?
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 Aeronautical Information Service (AIS) which publishes aeronautical data and aeronautical information in the 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, or by a person approved by CASA.
Additionally, the details of waypoints and navigation aids are contained in navigation system databases such as Global Navigation Satellite Systems (GNSS), Flight Management Computers (FMC) and Flight Management Systems (FMS).
What is the objective of CASR Part 175?
CASR Part 175 will create standards to ensure that the integrity and quality of aeronautical data and aeronautical information is maintained throughout the aeronautical data processing chain from data originator to AIS provider to commercial data service providers.
The purpose of CASR Part 175 is to ensure that:
- aeronautical information and data has enough quality assurance protocols around the supply process that reasonable assurance can be provided to the end-users (airline companies and pilots)
- data meets industry accuracy and resolution requirements
- the data has not suffered from transmission corruptions.
How do I provide aeronautical information?
The mechanism for the provision of aeronautical information protocol is a) nominate a responsible person as the Aeronautical Data Originator and b) acknowledge the appropriate Data Product Specification (DPS).
Data Product Specification details the requirements around accuracy, resolution, notification dates, format and other quality assurance topics. Please select the category relevant to you.
How will Airservices manage the collection of obstacle data under CASR Part 175?
Australia has an obligation under Annex 15 to provide obstacle data sets. CASR Subpart 175.E of the regulation outlines the obstacle data collection requirements. Airservices will manage the availability of obstacle data on behalf of Australia in order to meet Australia’s obligations. The obstacle data will be available to all users, however Airservices may charge for this data.
Is there a CASR Part 175 Manual of Standards (MOS)?
No. Provision for a MOS is included in CASR Part 175; however, a requirement for a MOS has not been identified at this stage.
Who should I contact if I have further questions?
For further clarification on your role as a supplier of aeronautical data, please contact Airservices via email to firstname.lastname@example.org. Information on CASR Part 175, including their development and implementation, is available on the CASA website.
Why do I have to complete the Data Product Specification (DPS) form?
It is a legal requirement. CASR Part 175 has been put into place to ensure that the integrity and quality of aeronautical data and information is maintained. CASR Part 175 is relevant to Aeronautical Data Originators (ADOs), Aeronautical Information Service (AIS) providers and commercial data service providers.
CASR Part 175.D.1 requires that a single point of contact be nominated from within the originators organisation to act as the AIP Responsible Person. This person will be responsible for providing aeronautical data and information to Airservices and must have the knowledge and competence to carry out the responsibilities of the role (CASR 175.445).
Who would the Aeronautical Data Originator - AIP Responsible Person be?
The person required by CASA to be the primary Aeronautical Data Originator – AIP Responsible Person must be the individual or an individual within the organisation that owns/operates the Aerodrome(s) with an ERSA FAC page. This person must complete a Data Product Specification form and send to email@example.com
In some instances the primary Aeronautical Data Originator – AIP Responsible person, may engage through formal agreements, and nominate other third parties to manage the activities and aeronautical information for their facility. In this case the primary Aeronautical Data Originator – AIP Responsible Person must ensure the third party also nominates and registers any individual(s) as an Aeronautical Data Originator by completing relevant section in the DPS. It must be noted that the primary Aeronautical Data Originator – AIP Responsible person will retain all CASR Part 175 accountabilities.
Nominated Aeronautical Data Originator – AIP Responsible person(s) are responsible for any information or change of information to the respective Aerodrome(s). This person would also be responsible for sending this information or change of information through to Airservices at firstname.lastname@example.org
What do I do for an Aircraft Landing Area (ALA) or Helicopter Landing Site (HLS) that doesn’t have an ERSA FAC page?
For aerodromes that only appear in ERSA Codes or on aeronautical charts there is no regulatory requirement for a formal DPS; however the AIS needs to be able to obtain the data from the responsible entity, be able to trace the data to its origin and must keep it up to date. Click here for the ALA/HLS Information Form – No ERSA FAC Page.
What does this mean to me?
You will need to update or review this information every 12 months (as a minimum). You will need to advise Airservices if another person takes over the position of Aeronautical Data Originator – AIP Responsible person.
Any information that comes to Airservices regarding changes to the aerodrome will be subject to a check of the DPS form. This is to ensure that only information from the authorised Aeronautical Data Originator – AIP Responsible Person is accepted. The DPS provides assurance that information published on behalf of aerodrome owners/operators, by Airservices, is current and has a high level of integrity and reliability.
How do I locate the Data Product Specification (DPS) form?
To access the Data Product Specification forms for Aeronautical Data Originators please visit CASR Part 175 – Airservices and You – Important Information – which category do you belong to?
If I fill out the form does this mean my runway will be a registered airstrip?
No. Completing the CASR Part 175 forms will not alter the current status of the aerodrome (e.g. uncertified, registered or certified). If you wish to have your aerodrome Registered or Certified you will need to contact CASA.
Do I have to advise Airservices if there are changes to my Aerodrome?
Yes, the Aeronautical Data Originator – AIP Responsible Person is required to notify Airservices as soon as practicable after becoming aware of a change to published aeronautical data or information about the location for which they are responsible (CASR 175.455).
Do I have to keep my airstrip in a certain condition?
CASR Part 175 does not cover the regulations regarding the condition of airstrips. Please refer to the appropriate regulation for registered/certified aerodromes (CASA Manual of Standards Part 139). For unregistered/uncertified aerodromes, the appointed Aeronautical Data Originator – AIP Responsible Person is required to inform Airservices if the airstrip becomes unusable.
If I choose to have an ICAO designator (y-code), what is involved in getting it?
To obtain an ICAO designator please complete the Information Form and applicable Data Product Specification if the aerodrome is to have an ERSA FAC page. If no ERSA FAC is required, please just submit the Information Form only. Requests should be emailed to email@example.com Please note: having an ICAO designator means that your landing strip will be in the public domain.
Do I have to have a designator?
No. If you choose not to have a designator the airstrip will not be published in any IAIP products. Flight planning can still be done to your airstrip without using an ICAO designator by using ZZZZ procedure as described in AIP ENR 1.10 -11 3.73.
