CASA 383/05 - Instructions – route specifications

Overview

The Civil Aviation Act 1988 was enacted by the Parliament of Australia to regulate civil aviation within the country and ensure the safety and efficiency of air navigation. The Act provides a framework for the regulation of air navigation and aircraft operations, including the issuance of regulations and instructions to enhance aviation safety. The Civil Aviation (Instrument Flight Rules) Instructions 2005, issued under the authority of the Act and the Civil Aviation Regulations 1988, provide updated guidance on navigating aircraft under Instrument Flight Rules (IFR), taking into account advancements in technology since the previous instructions were made in 1995. These instructions replace the outdated 1995 instructions and incorporate the latest technological developments to ensure better performance and safety standards compared to current ground-based navigation systems. The instructions were developed through substantial consultation, including input from the GNSS planning subgroup of the Australian Strategic ATM Group, and research conducted by Professor Brian O’Keeffe AO. As a disallowable instrument, the instructions are subject to tabling and disallowance in the Parliament, as stipulated by the Legislative Instruments Act 2003.

Scope and Application

The Civil Aviation Act 1988 applies to various persons, entities, and industries involved in the aviation sector, with its primary aim being the safety and regulation of civil aviation in Australia. Specifically, the Act empowers the Governor-General to make regulations concerning the safety of air navigation, as outlined in Section 98. This broad scope ensures that all entities, including airlines, pilots, air traffic control authorities, and aviation service providers, must adhere to the regulations and instructions set forth to maintain safety standards. The Civil Aviation Regulations 1988 further detail the application of these provisions, particularly through subregulation 179A, which allows the Civil Aviation Safety Authority (CASA) to issue instructions related to Instrument Flight Rules (IFR), specifying navigation methods and position-fixing procedures. These instructions, which replace the 1995 versions, have been updated to reflect technological advancements and have undergone substantial consultation, including input from the GNSS planning subgroup of the Australian Strategic ATM Group. The instructions are a legislative instrument subject to tabling and disallowance in Parliament, ensuring accountability and oversight. This comprehensive legislative framework underscores the commitment to maintaining high safety standards in Australia's aviation industry.

Key Provisions

The Civil Aviation Act 1988, specifically under Section 98, empowers the Governor-General to establish regulations pertaining to the Act, particularly those that concern the safety of air navigation. This authority is further detailed in subregulation 179A(1) of the Civil Aviation Regulations 1988 (CAR 1988), which allows the Civil Aviation Safety Authority (CASA) to issue instructions concerning Instrument Flight Rules (IFR). These instructions are designed to delineate the methods by which aircraft must be navigated and how a positive position fix should be obtained. They encompass general navigation procedures under IFR, the steps required for obtaining a positive position fix, and the use of radio navigation aids, including the specifics of the radio navigation systems that must be carried on an aircraft for various types of operations. This updated set of instructions, which supersede the 1995 instructions, reflects advancements in technology since that time. Under the Civil Aviation Act and the Civil Aviation Regulations 1988, the obligations imposed on parties and entities governed by these instructions are quite clear. Aircraft operators, pilots, and air navigation service providers must adhere to the specified methods and procedures for navigation and obtaining positive position fixes as outlined in the instructions. This includes ensuring that the appropriate radio navigation systems are installed and functioning correctly on aircraft for the specified types of operations. The instructions also impose an obligation on CASA to issue these instructions in a manner that ensures the safety of air navigation is maintained and improved. Moreover, these obligations are reinforced by the requirement for CASA to consult with relevant stakeholders, such as the GNSS planning subgroup of the Australian Strategic ATM Group, to ensure that the safety and performance standards are up-to-date and reflect current technological capabilities. The legislation also addresses the consequences for non-compliance with these instructions. According to subregulation 179A(3A) of CAR 1988, any instruction issued under subregulation 179A(1) is a disallowable instrument under the Acts Interpretation Act 1901. This means that the Parliament has the authority to review and potentially disallow the instruction. Furthermore, under subparagraph 6(d)(i) of the Legislative Instruments Act 2003 (LIA), such instruments are considered legislative instruments and are subject to the requirements of the LIA, including tabling and disallowance in the Parliament as stipulated in sections 38 and 42 of the LIA. The legislative process for these instructions involved substantial consultation, ensuring that the updated performance and safety standards are superior to those of current ground-based navigation systems, as confirmed through research conducted by Professor Brian O’Keeffe AO. In terms of penalties and consequences, while specific fines or criminal penalties are not detailed in the provided text, non-compliance with these instructions could potentially lead to regulatory action by CASA, including the imposition of fines, suspension or revocation of operating permits, or other enforcement actions. The instructions, having been issued by a delegate of CASA in accordance with regulation 7 of CAR 1988, carry the full weight of CASA's regulatory authority, and failure to comply could result in serious repercussions for the entities involved. It is important for all relevant parties to ensure strict adherence to these safety and operational standards to avoid any adverse consequences.
