Chapter 1         Introduction

Section 1.1    General

1.1.1    Background

1.1.1.1     The standards pertaining to the regulation of Aeronautical Telecommunication and Radio Navigation service providers in this Manual are established by the Civil Aviation Safety Regulations Part 171 — Approved Aeronautical Telecommunication and Radionavigation Service Providers. Part 171 has its basis in the Standards and Recommended Practices in Annex 10 to the Convention on International Civil Aviation.

1.1.2    Document set

1.1.2.1     The document hierarchy consists of:

(a)   the Civil Aviation Act 1988 (the Act); and

(b)   relevant Civil Aviation Safety Regulations (CASRs); and

(c)   the Manual of Standards (MOS); and

(d)   Advisory Circulars (ACs).

1.1.2.2     The regulatory documents establish, for service providers, a comprehensive description of system requirements and the means of meeting them.

1.1.2.2A   The Act establishes the Civil Aviation Safety Authority (CASA) with safety related functions relating to civil aviation and, in particular, the safety regulation of civil air operations in Australian territory.

1.1.2.3     CASRs establish the regulatory framework (Regulations) within which all service providers must operate.

1.1.2.4     The MOS comprises specifications (Standards) prescribed by CASA, of uniform application, determined to be necessary for the safety of air navigation. In those parts of the MOS where it is necessary to establish the context of standards to assist in their comprehension, the sense of parent regulations has been reiterated. The MOS is a disallowable legislative instrument. This means that it is an instrument that is not enforceable unless it is registered on the Federal Register of Legislative Instruments (FRLI). It must be tabled in both Houses of the Parliament within 6 sitting days after registration on FRLI, and is subject to scrutiny and disallowance by either House of the Parliament.

1.1.2.5      Readers should understand that in the circumstance of any perceived disparity of meaning between MOS and CASRs, primacy of intent rest with the CASR. Where there is any inconsistency between the regulations and the MOS, the regulations prevail.

1.1.2.6     Service providers must document internal actions (Rules) in their own Operational Manuals, to ensure compliance with the standards.

1.1.2.7     ACs provide recommendations and guidance material to illustrate a means, but not necessarily the only means, of complying with the Regulations. ACs may explain certain regulatory requirements by providing interpretive and explanatory material. It is expected that service providers will document internal actions in their own Operational Manuals, to put into effect those, or similarly adequate, practices.

1.1.3    Differences between ICAO standards and those in MOS

1.1.3.1     Notwithstanding the above, where there is a difference between a standard prescribed in ICAO Annexes and the Manual of Standards (MOS), the MOS standard shall prevail.

1.1.4    Differences published in AIP

1.1.4.1     Australian differences to the ICAO Standards and Recommended Practices are published in AIP GEN 1.7.

1.1.5    MOS documentation change management

1.1.5.1     Responsibility for the technical content of the MOS resides with the relevant technical area within Flight Standards Branch, Standards Division of CASA.

1.1.5.2     This document is issued and amended under the authority of the Director of Aviation Safety.

1.1.5.2A   Suggested changes to this MOS must be directed to the Manager, Air Traffic Management Systems Standards Section, Flight Standards Branch, Standards Division of CASA.

1.1.5.3     Requests for any change to the content of the MOS may be initiated by:

•      technical specialist areas within CASA;

•      Aeronautical Telecommunication and Radio Navigation service providers;

•      ATS service providers.

1.1.5.4     The need to change standards in the MOS may be generated by a number of causes. These may be to:

•      ensure safety;

•      ensure standardisation;

•      respond to changed CASA standards;

•      respond to amendments to the ICAO Annexes;

•      accommodate new initiatives or technologies.

1.1.6    Related documents

1.1.6.1     These standards should be read in conjunction with ICAO Annex 10 Volumes I to V inclusive, and ICAO Doc 8071 Volume I — Testing of Ground-Based Radio Navigation Systems.
