A Twenty-five-year Retrospective Analysis of Australia's Previous Defence Aviation Safety FrameworkF-0076-2020-1634810/5/2020
Australia has embarked on an extraordinary reform to design, develop and implement a new and contemporary Defence Aviation Safety Framework. The program seeks to establish a single Defence Aviation Safety Authority (DASA) and issue a comprehensive and integrated suite of Defence Aviation Safety Regulation (DASR) for initial and continuing airworthiness, flight operations, air navigation, aerodromes (inclusive of ship-borne heliports) and safety management systems. While reforms of this scale can often be triggered by reviews into major aircraft accidents, such as The Nimrod Review by Charles Haddon-Cave QC in October 2009, Australia initiated the reform when new aircraft fleets were being introduced and at a time of arguably high-levels of aviation safety. The purpose of this paper is therefore to explain the compelling reason for change; providing a twenty-five-year retrospective analysis of Australia’s previous Defence aviation safety framework to give a rich picture of the

Unsettled Topics in Automated Vehicle Data Sharing for Verification and Validation PurposesEPR20200076/3/2020
Unsettled Topics in Automated Vehicle Data Sharing for Verification and Validation Purposes discusses the unsettled issue of sharing the terabytes of driving data generated by Automated Vehicles (AVs) on a daily basis. Perception engineers use these large datasets to analyze and model the automated driving systems (ADS) that will eventually be integrated into future “self-driving” vehicles. However, the current industry practices of collecting data by driving on public roads to understand real-world scenarios is not practical and will be unlikely to lead to safe deployment of this technology anytime soon. Estimates show that it could take 400 years for a fleet of 100 AVs to drive enough miles to prove that they are as safe as human drivers.Yet, data-sharing can be developed – as a technology, culture, and business – and allow for rapid generation and testing of the billions of possible scenarios that are needed to prove practicality and safety of an ADS – resulting in lower research

A New Vision for Development Assurance Guidance2017-01-20579/19/2017
In the last several years, technical advances and regulatory pressures have motivated the need for flexible, simple, and performance-based solutions for conducting development assurance in support of a system safety assessment process. Additionally, the affected design space for commercial vehicles has been growing beyond the conventional regulations for airplanes, rotorcraft, engines, and propellers, addressed by current Aerospace Recommended Practices (ARPs). This space is beginning to include commercial technologies such as unmanned aerial systems, multi-stage spacecraft systems, and road-able aircraft. These developing areas are each accompanied with their own development assurance expectations in support of their safety criteria. Concurrently, the industry and regulators are working to simplify guidance for system safety and development assurance, which has been foundational in the aircraft industry for decades.

Control Engineering Approach in Safety Management SystemsF-0073-2017-122125/9/2017
ABSTRACT Safety Management Systems (SMS) are mainly based on an operational feedback approach for continuous safety enhancement. Closed loop approaches have been dramatically developed and applied in aeronautics by control engineers. In this article, SMS is redefined in terms of automatic control and this analogy leads to the identification of three classical feedback strategies. The theoretical effect of these strategies on performances is also discussed. As in any closed loop systems, the importance of understanding how the mission stakeholders react will be found to be particularly crucial. The last aspect of this analogy is discussed through quantitative SMS, or the standard use of SMS indicators. Several aspects of decision making and quantitative analysis are then discussed.

Enhanced Safety Management and Risk Mitigation through Robust HFDMF-0073-2017-120855/9/2017
ABSTRACT Helicopter Flight Data Monitoring (HFDM) can be a central and effective component of an operator's safety management strategy. By capturing and processing operational information from aircraft flight data, the operator/owner can identify safety hazards, facilitate monitoring and assessment of the interaction between the pilot and the aircraft, initiate remedial actions, and support continuous improvement of the safety management system. The Robust HFDM system described in this paper also provides improved results via automation of data download and reporting. Automation is achieved by formalizing the concept of a flight operation, adding exceedance reporting, and improving the HFDM architectural design to allow for the transfer of data to secure ground based storage. In the extreme, robust HFDM also provides protection of data in the event of a mishap event that would usually only be available via post incident analysis of a crash survivable memory.

The Evolution of Airline Safety and Security Programs2013-01-22299/17/2013
Career paths are not something that one can predict. They are as much about being in the right spot at the right time with the desired skill set as they are about having a detailed, calculated plan. How does one go from being a young Original Equipment Manufacturer (OEM) test engineer to being an airline Senior Vice President of Safety, Security and Compliance and the joint industry/FAA co-chair of the Commercial Aviation Safety Team? It is a bit unusual that a non-pilot ends up on an airline Operations Specification listed as the Federal Aviation Regulations (FAR) Part 119 Director of Safety for one of the largest airlines in the world. Engineering background and experience were key stepping stones on that journey along with a healthy dose of skepticism. An initial assignment to make an airline's safety program robust, credible and data driven, much like the very successful aircraft reliability programs, set the direction and path forward. Today's commercial airline safety and

Soaring with Eagles: Birdstrike Analysis in the Design and Operation of New Airplanes2013-01-22349/17/2013
We live in an era of increasing twin-engine commercial airplane operations, with large and very quiet high bypass ratio engines. At the same time, due to several decades of increased attention to the environment, we have large and increasing hazardous species bird populations. These trends, when combined, are not a prescription for continued assurance of a remarkable and enviable safety record for commercial aviation. Therefore, greater diligence must be placed on the evaluation of the current and future aviation wildlife hazard. We have some new weapons in this fight for greater capability to live with this situation. The basic problem is that different databases are populated independently from one another and often contain conflicting, contradictory, and erroneous data. Databases that were used individually, but not necessarily combined, are being utilized in a conjoined methodology to give us a better picture of the actual risk involved. And new analytical techniques are being

Towards “Vision Zero”2012-01-02884/16/2012
“Safe Driving” is an essential world-wide automotive requirement. The demand for “Safe Driving” is particularly high in industrialized countries, but it is also growing in the fast-developing nations. However, the annual reduction of serious traffic injuries and fatalities is still too low and the target to halve the number of people killed in traffic in the European Union from 2001 to 2010 has not been met. Essential influences to close this gap include legislation, road traffic regulations and monitoring, technical improvement of vehicles including active and passive safety systems, the increase of the equipment rate for safety functions and the re-design of traffic infrastructure for safety reasons. During the last years several countries in Europe started to consider these aspects combined in an integrated and general traffic safety policy, i.e. “Vision Zero” in Sweden. This overall approach provides the basis for the ISO 39001 “Road traffic safety management”, which is planned to

Determining a Safety Baseline for Unmanned Aircraft Systems2011-01-268610/18/2011
Unmanned Aircraft Systems (UAS) emerge as a viable, operational technology for potential civil and commercial applications in the National Airspace System (NAS). Although this new type of technology presents great potential, it also introduces a need for a thorough inquiry into its safety impact on the NAS. This study presents a systems-level approach to analyze the safety impact of introducing a new technology, such as UAS, into the NAS. Utilizing Safety Management Systems (SMS) principles and the existing regulatory structure, this paper outlines a methodology to determine a mandatory safety baseline for a specific area of interest regarding a new aviation technology, such as UAS Sense and Avoid. The proposed methodology is then employed to determine a baseline set of hazards and causal factors for the UAS Sense and Avoid problem domain and associated regulatory risk controls.

Will the Real Solution Please Stand Up2009-01-310611/10/2009
This technical paper and presentation addresses the need for more refined, pervasive and highly engaged technical leadership in the system safety discipline. Systems engineering disciplines have been led to believe that by following a single industry standard, generic plans, inflexible processes, proven methods and techniques a system with low safety risk will evolve with little rework. The truth is there is no prescriptive one size fits all approach, or a convention that will anticipate and cover all needs. In several domain areas, especially modern military and commercial airborne systems, diverse technology and functionality have been evolving with such high complexity and criticality that collective processes will not work unless seasoned leaders allow creativity and innovation to be part of the safety culture. Leaders must have intuitive engineering and operations judgment to determine how to best allocate effective resources to meet system safety goals and objectives. This means

Integrated Safety Management System2009-01-317111/10/2009
The Safety Management System requires a structured Risk Management Process to be effective. In the technical fields where numerous potentially catastrophic risks exist, processes and procedures need to account not only for the hardware random failures but also of human errors. The technology has progressed to the point where the predominant safety risks are not so much the machine failures but that of the human interaction. Accidents are rarely the result of a single cause but of a number of latent contributing factors that when combined result in the accident. In the Aerospace industry, the operational risk to the fleet is assessed by the manufacturer and the operator independently and is used in safety and/or regulatory decision-making. For the manufacturer, the risk assessment is a philosophy whereby risk of a potential or actual occurrence is evaluated in comparison to the event analyzed in the system safety assessment or structural analysis performed for certification of the

Accident Data Collection Methodology for Building a Traffic Accident Database for Tamil Nadu (India)2009-26-00081/21/2009
India is facing the challenge of reducing road accident fatalities, which claim close to 100,000 lives every year. Road infrastructure is slowly improving, but the number of vehicles on the road is rising fast and so is the number of road accidents, which continue to increase year after year. The data collected by law enforcement agencies is not detailed enough to identify causes and develop solutions. Traffic accidents need to be investigated in detail to include specifics concerning crash location, vehicle damage and injuries sustained by road users. The development of such a detailed database requires the co-operation of a number of government and private organizations associated with road traffic collisions. The foundation for data collection activities is a road traffic accident notification network that enables access to accident details, crashed vehicles, and injury reports in a timely manner. This paper describes the methodology for developing a road traffic accident database

Control of Sideslip and Yaw Rate in Cars Equipped with 4-Wheel Steer-by-Wire2004-01-20765/4/2004
This paper presents a new steering controller for cars equipped with 4-wheel steer-by-wire. The controller commands the front and rear steering angles with the objective of tracking reference sideslip and yaw rate signals describing the desired car lateral dynamics. In addition, the controller automatically rejects any disturbances in sideslip and yaw rate caused, for example, by μ-split braking manoeuvres or lateral wind gusts. The structure of the controller is based on a simplified model of the lateral dynamics of 4-wheel steering cars. This structure allows an originally complex multivariable control design problem to be broken down into two simpler single-input, single-output (SISO) control design problems by means of the Individual Channel Design (ICD) methodology. Within the proposed structure, individual sideslip and yaw rate controllers, valid for varying vehicle speed, can be designed using classical linear control design techniques. An anti-windup scheme has been

Is ‘Safe’ Safe Enough?2001-01-26719/11/2001
This paper advances the proposition that although the outside world perceives aviation as ‘safe’ and accepting that the accident rate is slowly falling, there remain a number of accidents every year which appear to have common causes. Is aviation really a learning industry? Could significant progress be made by requiring airlines to demonstrate that lessons have been learnt and procedures changed accordingly? Where the cause is technical, change occurs through the manufacturer and the regulator. Where operating procedures and human factors are involved changes occur slowly, if at all. The author suggests three courses of action for improvement.
