Risk-management of UAS robust autonomy for its integration into civil aviation safety frameworks
No full textThis paper discusses a model of the civil aviation reg- ulation framework and shows how the current assess- ment of reliability and risk for piloted aircraft has limited applicability for Unmanned Aircraft Systems (UAS) with high levels of autonomous decision mak- ing. Then, a new framework for risk management of robust autonomy is proposed, which arises from combining quantified measures of risk with normative decision making. The term Robust Autonomy de- scribes the ability of an autonomous system to either continue or abort its operation whilst not breaching a minimum level of acceptable safety in the presence of anomalous conditions. The decision making associ- ated with risk management requires quantifying prob- abilities associated with the measures of risk and also consequences of outcomes related to the behaviour of autonomy. The probabilities are computed from an assessment under both nominal and anomalous sce- narios described by faults, which can be associated with the aircraft’s actuators, sensors, communication link, changes in dynamics, and the presence of other aircraft in the operational space. The consequences of outcomes are characterised by a loss function which rewards the certification decisio
The Smart Skies Project
No full textSmart Skies is an international research project exploring the development and demonstration of future aviation technologies which facilitate the more efficient utilisation of airspace for both manned and unmanned aircraft. These technologies include autonomous vision-based collision avoidance systems, autonomous airspace separation management systems and a mobile ground-based radar system to support non-segregated UAS operations within the NAS. This presentation will provide an introduction to the key programs of research, detail results from recent flight trial activities and will outline future directions for the project
Determination and Evaluation of UAV Safety Objectives
No full textThe integration and acceptance of routine Unmanned Aerial Vehicle (UAV) operations within the civilian airspace system hinges on the ability of UAV developers, operators and regulators to prove that UAVs, at minimum, have an equivalent level of safety to that of human-piloted aircraft. Regulations, which govern the safe design, manufacture, maintenance and operation of UAV systems, are to be defined so as to ensure this safety objective is met. Therefore, it is important to provide discussion on the definition and application of such safety objectives to ensure appropriate requirements are defined. \ud
\ud
Safety objectives are defined using a historical analysis of human-piloted aviation accidents. The results of this empirical analysis are then compared against those proposed in draft regulations and in similar studies. The limitations to the approach and the metrics used are also discussed.\ud
\ud
A simple ground fatality expectation model is used to illustrate the impact that varying safety objectives have on the design and operation of UAVs. Specific applications of border security, operations over urban environments and precision farming in the sugarcane industry are investigated. \ud

The final section of this paper provides discussion on the public acceptance of risk. The paper highlights a number of key factors which influence the acceptance of risk and the impact these factors have on the definition of safety objectives
Pilotless aircraft: the horseless carriage of the twenty-first century?
No full textThis paper identifies recurring issues in the regulation of new technologies through an historical review of the risk management of automobiles in the 1800s. Parallels are drawn between the regulation of early automobiles and that of the regulation of Unmanned Aircraft Systems (UASs) today. It is found that many of the regulatory challenges facing UASs are analogous to those which faced the automobile industry more than a century and half ago and that the need for informed and objective decision making in policy development is reinforced. A systems engineering approach, based on general systems theory and decision-based design principles, is then proposed as a means for improving the objectivity, transparency and rationality in the risk management decision making process. An example risk management decision making scenario is given within the context of a small UAS operating over a populated area. The results obtained from this case study illustrate how even simple analysis can support the decision making process and highlights some of the potential challenges in the regulatory approach currently applied to UASs
