CD 1424AS - MOS Part 173 - instrument flight procedure design
The Civil Aviation Safety Authority (CASA) drafted the Part 173 Manual of Standards (MOS) in 2001/2002. At that time, the drafting team did not envisage the use of aircraft flight simulators in flight validation work; however, it is now an established international practice to use flight simulators for validation of terminal instrument flight procedures. ICAO Doc 9906 sets out situations when a simulator should be used, and prescribes mandatory use of simulator validation for RNP AR procedures.
Purpose and scope of the proposed amendments
Proposed amendment to reflect standards for design:
The lack of reference to ICAO Doc 9905 in the Part 173 MOS precludes the criteria in that document from having any legal standing in Australia. Currently, these criteria can only be used after CASA has granted an exemption against the applicable parts of the Part 173 MOS. The proposed amendment would change nine subparagraphs in the Part 173 MOS to include reference to Doc 9905 and, consequently, would allow the associated exemptions to be revoked.
Proposed amendment to reflect flight validation process:
Amendments to three paragraphs are proposed to clarify Part 173 MOS, as is does not specifically mention the use of aircraft simulators during the flight validation process.
