Part 7: Appendices

Involvement in International Civil Aviation Organization (ICAO) activities

CASA plays an essential role in Australia's participation in International Civil Aviation Organisation (ICAO) activities relating to the development of international aviation safety standards. The following are indicative of the contributions made by Australia's expertise to ICAO's work during 2004-05.


In consultation with ICAO and other international aviation authorities, CASA is contributing to the development of a strategy to allow the introduction of the Airbus A380 into aerodromes without major airport works requirements.

Asia Pacific Planning & Implementation Regional Group (APANPIRG)

CASA participates regularly in the various study groups of this ICAO forum within our region (e.g regional Airspace Safety Monitoring Study Group; Air Traffic Management, Aeronautical Information Service & Search and Rescue Study Group; Communications, Navigation, Surveillance & Meteorology Study Group).

Flight Crew Licensing and Training

Australia again chaired the Flight Crew Licensing and Training Panel (FCLTP) that brought to completion the work programme given to it by the Air Navigation Commission of ICAO. The FCLTP was able to make unanimous recommendations on a wide range of modifications to current Standards and Recommended Practises (SARPs) and a significant set of new SARPs for Annex 1 - Personnel Licensing. The Air Navigation Commission was able to remark most positively on the standard and timeliness of the Panel's work along with the international spirit of co-operation that lead to consensus on all of the Panel's recommendations.

In particular, Australia was able to make significant contributions to the competency-based standards for the new Multi-crew Pilot Licence (MPL), recognition of synthetic training devices for credit towards licences, the rewrite of Chapter 2 and the clarification of the intent of a number of SARPs in Chapter 1 which had been variously interpreted by States to date. Australia was also instrumental in philosophy and content development of the new Procedures for Air Navigation Services - Training (PANS-TRG) document which supports Annex 1 to the convention.



CASA continues to make significant contributions to the work of the ICAO Operations Panel (OPSP). The Air Navigation Commission (ANC) has tasked the OPSP with developing Standards and Recommended Practices (SARPs) and Guidance Material (GM) for Annex 6 of the International Convention on Civil Aviation, and related operational aspects of Procedures for Air Navigation Services (PANS - OPS and PANS ATM).

A CASA staff member was appointed as Chair of the Operations Panel at OPSP/6 held in Montreal in September 2003, and has continued to lead and guide the discussions of this group of international technical experts through three subsequent meetings of the OPSP Working Group. Through his involvement, CASA is continuing to play a leading role in the development of SARPs and GM for Extended Diversion Time Operations (ETOPS) regulations governing ETOPS are under development in a joint CASA/CAA New Zealand project team, which this Officer also chairs.

These important regulations will harmonise the requirements of Australia and New Zealand and are expected to have a flow-on effect back through to the ICAO OPSP work as other States take note of what Australia and New Zealand are doing.

OPSP technical subgroups are established to deal with SARPs and GM relating to flight and duty time limitations, head-up guidance systems; electronic flight bags; single-engine IMC (instrument meteorological conditions) operations; land and hold short operations (LAHSO); precision radar monitoring (PRM) operations; and operations on wet and contaminated runways. Other CASA Officers contribute from time to time through the OPSP Chairman to the work of these subgroups. For example, a significant percentage of the amendment proposals to Annex 6 Part I contained in a recent ICAO State Letter in respect of the operation of single-engine turbine-powered aeroplanes in IMC are largely the work of a CASA Officer.

The operational issues under review by the OPSP have considerable global significance, and the respect with which the opinions and experience of CASA Officers are regarded within ICAO and in the OPSP forum is a clear indication of Australia's leading status in the world aviation arena.

Separation and Airspace Safety Panel (SASP)

SASP is responsible for the development of ATC standards and separation minima based on models and agreed Target Levels of Safety (TLS). The work of the panel in 2005 and 2006, as presently scheduled, is to continue to focus on the development of provisions for: air traffic control (ATC) separation minima for use with automatic dependent surveillance - broadcast (ADS-B); longitudinal distance-based separation minima for global navigation satellite systems (GNSS)-equipped aircraft; horizontal separation minima less than 56 km (30 NM) for appropriately approved RNP aircraft; and separation minima and procedures for use in association with highly accurate aircraft navigation systems in terminal control areas (both radar and non-radar).

Australia has had a high level of participation in SASP's development of a 'radar like" separation minima using ADS-B and a PANS ATM Doc 4444 amendment detailing the separation minima and operational procedures. Australia is also active in the SASP preparation of a safety "roadmap" for nations to develop an ADS-B Implementation Safety Case.

SASP is now refocusing its activities to developing uniform system wide approaches to ATM safety management including the safety metrics used. CASA is a member of the team formed for this approach which will include the harmonisation of safety indicators, development of predictive indicators, setting of safety targets and guidance to States on acceptable levels of safety.
