Project AS 10/23 - Terminology amendment and review of Terminal Instrument Flight Procedure withdrawal protocol - Manual of Standards Part 173 - Standards applicable to Instrument Flight Procedure Design
Project closed 19 April 2012.
Following publication of NFRM AS 10/23-24 on 13 April, this project has now been completed. Clarifying terms used in relation to, and withdrawal protocol for Terminal Instrument Flight Procedures - Amendments to CASR Part 139, CASR Part 173, the CASR Dictionary, MOS Part 173.
Amendments to CASR Parts 139 and 173, the CASR Dictionary and MOS Part 173
CASA has published the legal drafts for amendments to CASR Parts 139 and 173, the CASR Dictionary and MOS Part 173 for project AS 10/23 (Terminology amendment and review of Terminal Instrument Flight Procedure withdrawal protocol - Manual of Standards Part 173 - Standards applicable to Instrument Flight Procedure Design) and project AS 10/24 (Clarifying terms used in relation to Terminal Instrument Flight Procedures).
As a result of comments received from the earlier consultation and further review, these amendments have been revised. Subject to approval by the Director of Aviation Safety, CASA intends to proceed with final rule making and will publish a Notice of Final Rule Making (NFRM) in due course.
Please note that the Amendment Regulations also relate to project: AS 08/08 (Amendment of CASR Part 139 and MOS Part 139 - Regulations for the control of vehicles operating on the manoeuvring area of certain high-density aerodromes).The amendments to the CASRs for projects AS 10/23, AS 10/24 and AS 08/08 have been combined by OLDP in the one set of Civil Aviation Safety Amendment Regulations. Schedule 1 of the Amendment Regulations contains the amendments related to projects AS 08/08 and AS 10/24. Schedule 2 of the Amendment Regulations contains the amendments related to project AS 10/23.
Readers should also note that, in addition to the amendments to CASR Part 173 resulting from projects AS 10/23 and AS 10/24, an amendment to CASR 173.035 (Designing terminal instrument flight procedures requires procedure design certificate) is also being made. This amendment was initiated by OLDP to address a drafting error in the earlier version of the provision and to present the provision in clearer terms. There is no change in the policy intent of the provision.
Currently, it is a strict liability offence under CASR 139.030 for a person to operate a publicly available aerodrome with a non-precision approach runway, unless the aerodrome is certified or registered.
This raises immediate safety concerns because only at certified or registered aerodromes does CASA require the appointment of an Aerodrome Reporting Officer to monitor the condition of the aerodrome, with a primary function being to ensure that there are no obstacles that infringe the instrument approach surfaces to the aerodrome.
The problem CASA faces is that the term non precision runway does not cover all categories of operation for which instrument flight procedures are produced. There is, therefore, the possibility of flight procedures, other than non precision flight procedures, being produced for aerodromes which are neither registered nor certified.
At such aerodromes, monitoring the approaches to the aerodrome is not obligatory and may not be undertaken to the required standards. The potential, therefore, exists for aircraft to collide with unreported obstructions to such aerodromes or reduce the safety margins.
To investigate the amendments which may be required in the CASR's and in MOS 173 in order to address this issue, and the use of inconsistent terminology as it relates to instrument flight procedures.
This project was approved by Peter Boyd, EM Standards Development and Future Technology on 17 November 2010.
