The ATSB Annual Review 2003 documents ATSB's achievements and safety activities from 1 July 2002 to 30 June 2003 and outlines its business planning for 2003-2004 Executive Director's message During 2002-03, the ATSB assisted the Minister for Transport and Regional Services with new legislation to enable the Bureau to investigate rail accidents on the increasingly important interstate system. The Transport Safety Investigation Act 2003 (TSI Act) also updates and harmonises the Bureau's aviation and marine investigative powers. The Transport Safety Investigation Regulations 2003 were also…

This project investigated the use of weather radar displays in commercial aviation. Three studies are described. The first study used an expertise model of the use of weather radar displays to classify aircraft accident and incident reports. The three data sources used were the Federal Aviation Administration Accident/Incident Data System, the National Transportation Safety Board Accident and Incident Database, and the Aviation Safety Reporting System. Although generalisation of the outcomes is limited, the results provide some evidence to suggest that where the use of weather radar was…

The ATSB Annual Review documents ATSB's achievements and safety activities from 1 July 2003 to 30 June 2004 and outlines its business planning for 2004-2005. Executive Director's message The ATSB had a busy and productive year in 2003-04 in all modes. In its aviation activities,the ATSB released 63 investigation reports including important reports on fatal accidents at Hamilton Island, Bankstown, Moorabbin and Toowoomba and on a Saab 340 serious icing incident near Bathurst. The Bureau generated 46 air safety recommendations including those arising from the Hamilton Island investigation, on…

Alcohol is a widely used drug, and its abuse is a serious public health problem. Alcohol has many widespread effects on the body, and impairs almost all forms of cognitive function, such as information processing, decision-making, attention and reasoning. Visual and vestibular functions are also adversely affected. The performance of any demanding task, such as flying an aircraft, is thus impaired by the effects of alcohol. Many studies have shown a significant proportion of aircraft accidents associated with alcohol use. Alcohol increases the risk of spatial disorientation, hypoxia and poor…

Cannabis is a commonly used recreational drug, which has widespread effects within the body. Smoking is the most common form of administration. The adverse effects of cannabis on behaviour, cognitive function and psychomotor performance are dose-dependent and related to task difficulty. Complex tasks such as driving or flying are particularly sensitive to the performance impairing effects of cannabis. Chronic cannabis use is associated with a number of adverse health effects, and there is evidence suggesting the development of tolerance to chronic use as well as a well-defined withdrawal…

The vast majority of Australian civil fatal aircraft accidents occur in general aviation (GA) operations. This study examined Australian civil GA fatal accidents for the period 1991 to 2000, and covers fatal accident numbers and rates by aircraft type and operational grouping, timing of accidents, injury levels, pilot demographics and fatal accident types. Between 1991 and 2000 inclusive, there were 215 fatal accidents and 413 associated fatalities. Over the ten-year period there were 1.2 GA fatal accidents per 100,000 hours flown. The annual fatal accident rate decreased from 1.6 fatal…

Night Vision Goggles (NVGs) are binocular devices that enhance unaided night vision for pilots. Typically, NVGs are mounted on a pilot's helmet. This position enables pilots to look through the goggles outside the cockpit or under the goggles at flight instruments. By enabling the pilot to see in the dark, NVGs have the potential to improve the safety of visual flight at night. In most conditions, night vision goggles provide pilots with a significant increase in the quality of visual information compared with unaided night vision. They allow the pilot to see the horizon, objects, terrain and…

Weather-related general aviation accidents remain one of the most significant causes for concern in aviation safety. Previous studies into the factors associated with weather-related general aviation occurrences have typically compared accident and non-accident cases. In contrast, this study does not concentrate on occurrence outcome. Instead, the emphasis is on the different behaviours that pilots exhibit in the face of adverse weather and, by inference, on the decision making processes that underlie those behaviours. The work of this study is based on a set of 491 aviation accident and…

The twin-engine power loss accidents were analysed to identify the types of accidents that occurred. Ten of the 11 fatal accidents subsequent to a power loss in twin-engine aircraft were the result of an in-flight loss of control. In contrast, the majority of non-fatal accidents subsequent to a power loss were primarily the result of degraded aircraft performance and resulted in aircraft being forced landed. When a twin-engine aircraft sustains a loss of power, the resulting power output can produce a power condition that is either asymmetric or non-asymmetric. The twin-engine power loss…
