differences which are adopted by Australia; and

(C)        new or developing standards; and

(b)         RNP AR APCH procedures, the design standards are contained in:

(i)            PANS OPS; and

(ii)          this MOS which comprise:

(A)        additional design standards not included in PANS-OPS; and

(B)        differences which are adopted by Australia; and

(C)        new or developing standards; and

(iii)        ICAO Publication Doc 9905-AN/471, also referred to as the Required Navigation Performance Authorization Required Procedure Design Manual (ICAO Doc 9905).

1.1.2                   Differences between ICAO documents and standards in the MOS

1.1.2.1              Notwithstanding the above, where there is a difference between a standard prescribed in ICAO documents and the MOS, the MOS standard shall prevail.

1.1.3                   Document Set

1.1.3.1              The document hierarchy consists of:

(a)         relevant Civil Aviation Safety Regulations (CASRs);

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

(c)          Advisory Circulars (ACs).

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

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

1.1.3.4              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.

1.1.3.5              Readers should understand that in the circumstance of any perceived disparity of meaning between MOS and CASRs, primacy of intent rests with the regulations.

1.1.3.6              Service providers must document internal practices (Rules) in their own operational manuals, to ensure the maintenance of and compliance with standards.

1.1.3.7              ACs are intended to provide recommendations and guidance to illustrate a means, but are 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.

1.1.4                   MOS Documentation Change Management

1.1.4.1              Responsibility for the approval of the publication and amendment of the MOS resides with the Branch Head, Airways, Air Traffic and Aerodrome Standards Branch, of the Aviation Safety Standards Division, Civil Aviation Safety Authority (CASA).

1.1.4.2              This document is issued and amended under the authority of the Branch Head, Airways, Air Traffic and Aerodrome Standards Branch.

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

(a)         technical specialist areas within CASA;

(b)         instrument approach procedure designers;

(c)          ATS service providers;

(d)         pilots and ATC staff;

(e)         other aviation industry service providers.

1.1.4.4              The need to change standards in the MOS may be generated by a number of
