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 a legislative instrument that becomes effective following registration on the Federal Register of Legislative Instruments (FRLI). It must be tabled in both Houses of Parliament within 6 sitting days following registration and is subject to scrutiny and disallowance by 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 rests with the regulations. 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 the maintenance of and compliance with standards.

1.1.2.7              ACs are intended to provide recommendations and guidance 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 materials.  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 documents and the Manual of Standards (MOS), the MOS standard shall prevail.
