service providers must operate.
       1.1.2.4The 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
       1.1.3.1Notwithstanding 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.
