The Australian Air Traffic Service (ATS) system provided by the Civil Aviation Authority (CAA) is responsible for the provision of a safe, efficient, and cost effective air traffic control and advisory service to the aviation industry within domestic and international (oceanic) airspace. This BASI study conducted during 1992 was aimed at understanding the organisational factors and system characteristics, and the underlying failures which lead to certain ATS occurrences. BASI's endeavour was to provide the CAA with a method which would allow the cause of a particular problem to be tracked…

The introduction of new technology to aviation has generally resulted in benefits to safety and efficiency, but has also resulted in a range of new human factors and operational difficulties. BASl's Advanced Aircraft Research Project began in response to a number of perceived problems, which included data entry errors, monitoring failures, mode selection errors and the inappropriate manipulation of automated systems. For the purpose of this study, advanced technology aircraft, or automated aircraft, are defined as aircraft equipped with cathode ray tubeshquid crystal displays and flight…

This report deals with information supplied by respondents to the Advanced Technology Aircraft Safety Survey and provides a detailed analysis of answers to both the 'open' and 'closed' questions. Accident, incident and anecdotal evidence indicates that the introduction of new technology to aviation has generally resulted in benefits to safety and efficiency (Norman & Abbott 1988), but has also resulted in a range of new human factors and operational difficulties. BASI's advanced technology aircraft research project was begun in response to a number of perceived problems such as data entry…

A Failure to Comply incident is defined as an air safety incident in which flight crew fail to follow an ATS clearance in controlled airspace. During 1994 BASI recorded an increase in the frequency of incidents involving failures to comply with ATS clearances. This trend continued in 1995 and the largest increase appeared to be associated with the introduction of new arrival and departure procedures at Sydney airport. The Bureau conducted a preliminary study to confirm these trends and concluded that a comprehensive study was necessary. This report draws on data collected during the…

Accident, incident and anecdotal evidence indicate that the introduction of new technology to aviation has generally resulted in benefits to safety and efficiency (Norman and Abbott 1988). Information published by Boeing Commercial Airplanes indicates that in general, accident rates have been declining with each successive technological advance over the last thirty years (Boeing 1988). However, new technology has also resulted in a range of new human factors and operational difficulties. New tools invariably change the way a job is done and new aircraft are no exception. The work of pilots…

A VCA occurs when a pilot enters controlled airspace without a clearance. Controlled airspace is a section of airspace surrounding an airport with a tower, and/or airspace up to a certain altitude overlying Australia. This airspace may or may not be radar monitored. The controller needs to be aware of all aircraft within hisher section of controlled airspace so as to provide a complete traffic service. Pilots are required to request a clearance before entering the airspace.

The history of helicopters in Australia did not begin until after World War II. Although in 1943 the Amy planned to use helicopters for reconnaissance work in New Guinea, it was not until 1948 that the R AAF received its first helicopters, Sikorsky S51s. Civil helicopters followedin 1956, with the import of a Bristol Sycamore for ANA and a Hiller 12c for TAA early in that year. In May 1956 ANA'S helicopter began operating in Tasmania.

This study analyzed occurrences involving fuel starvation - the state in which the fuel supply to the engine is interrupted although there is adequate fuel onboard the aircraft, and fuel exhaustion - the state in which the aircraft has become devoid of usable fuel. Fuel starvation has been a more common type of occurrence; however, the probability of the occurrence resulting in an accident has been greater for fuel exhaustion. starvation accidents and 8 fuel exhaustion accidents per annum in Australia since 1969. Fuel-related engine failures have constituted 34% of all engine failure…

While most runway excursions are relatively minor with no serious injuries or aircraft damage occurring, they do have the potential to pose a serious risk to public safety and infrastructure. This has been illustrated by several significant runway overruns around the world in 2007 and 2008, resulting in hundreds of on-board fatalities, as well as ground fatalities and significant property damage in communities adjacent to airports. Further analysis of the Ascend World Aircraft Accident Summary set of 120 runway excursions on landing involving commercial jet aircraft between 1998 and 2007 (…

In 2009, the Australian Transport Safety Bureau (ATSB) produces its third edition of Australian Aviation Safety in Review as part of its role to enhance public awareness of aviation safety. This Review has been developed to provide a readily accessible analysis of the Australian aviation industry, with a major focus on communicating the key safety trends. This publication covers the major aircraft operation categories of passenger transport (regular public transport and charter) and general aviation. Sport and recreational aviation is also discussed, as is the burgeoning trend towards amateur…
