1.1.2 Background

       1.1.2.1CASA may issue navigation approvals to Australian operators under CASR Subpart 91.U, in the form of navigation authorisations, to enable operators to meet specific navigation requirements set by Australia and other States.

       1.1.2.2This MOS sets out the standards to be met for the issue of navigation authorisations.

       1.1.2.3The standards include:

(a) equipment requirements; and

(b) flight crew training requirements; and

(c) continuing airworthiness; and

(d) operating procedures; and

(e) reporting of navigation or system errors.

1.1.3 Document set

       1.1.3.1The relevant legislation and legislative instruments are:

(a) the Act; and

(b) the CASR; and

(c) the MOS.

       1.1.3.2The Advisory Circulars (ACs) are also part of the relevant documents, but they are advisory rather than legislative.

       1.1.3.3The Act establishes CASA with functions relating to civil aviation, particularly the safety of civil aviation, and for related purposes.

       1.1.3.4The CASR establishes the regulatory framework (regulations) within which all service providers must operate.

       1.1.3.5This MOS is issued by CASA as uniformly applying specifications or standards necessary for the safety of air navigation. Where it would help to see the context of the standards, the relevant CASR regulations are mentioned.

       1.1.3.6This MOS is a legislative instrument. This means that it becomes effective on the day after it is registered in the Federal Register of Legislative Instruments. It must be tabled in Parliament within 6 sitting days after it is registered and Parliament can disallow it or any of its provisions.
