In many domains such as aerospace and civil aviation in general, safety assessment is performed with old and outdated methodologies when it comes to complex systems involving software and/or human interactions. Newer and more effective methodologies exist, such as System-Theoretic Process Analysis (STPA), but their adoption and implementation by the industry is rather long and not marked. One of the reasons explaining it is the lack of time to train employees and create new procedures within the organization, as well as the time-demanding nature of the analysis and the related processes . This project tackles this issue by bringing an automation tool that will reduce the time of performing an STPA analysis and will increase its efficiency at the same time. Overall, safety would be increased in organizations willing to implement such a tool to adopt STPA. The challenges will lie in defining a conceptual model as well as defining and formalizing the data that will be mapped to this conceptual model.

Safety in aviation is very important and discussed aspect today. The vision to reduce the number of air accidents and incidents, and thus the loss of life and financial costs leads to the development of safety. Supranational authorities at the world and European level issue standards, recommended practices or other requirements focused on aviation safety oversight. A relatively new proactive approach to safety must be implemented by both the organizations and the member states. One of the requirements is also the introduction of SSP (State Safety Programme) and NASP (National Aviation Safety Plan) in state aviation oversight authorities. However, it is necessary to have credible inputs to implement SSP and NASP that will show us the safety performance of the system. Safety performance monitoring is already being implemented but measuring performance in the current systems has its limitations. To compensate the shortcomings of performance measurement, it is appropriate to work with available safety data in systemic way, in this project based on STAMP (System-Theoretic Accident Model and Process), which provides a comprehensive view from which it is possible to better identify inputs for creating and updating SSP and NASP. The proposed project aim is to improve the level of safety oversight at state aviation oversight authorities. The main result will be a methodology describing the functional process of working with safety data leading to the inputs for the establishment of SSP and NASP. As part of the project research, regular consultations with experts from the Civil Aviation Authority of the Czech Republic will take place, which will serve as a validation of the project results.

A broad portfolio of available and affordable unmanned aerial vehicles (UAV), their diversity of construction, the level of autonomy and integration of the auto-pilot systems has forced the European Union to modify present drone categorization legislation. New regulation is besides the weight of the UAV now considering also other performance characteristics such as maximum velocity in horizontal flight or maximum height above the launch point. Based on these four specifications is an UAV (drone) assorted into one of the 4 categories. The methodology of testing as well as the testing equipment will greatly influence the accuracy of the proper classification of the product and will affect the pricing. The above will be applicable particularly for the drones of C0 and C1 category with maximum take of weight of 250 g for C0, ev. 900 g for C1. The goal of this project is to propose the affordable methodology of the exact and dynamic testing of the above-mentioned characteristics used for the drone's categorization, in particular the maximum flight height and maximum horizontal speed. The primary focus will be on the Quadro-copters whilst the whole presented project has the ambition to define further flight characteristics that might influence the safety of utilization of unmanned aerial vehicles and their categorization within the valid EU legislation. The outcome of the project will be the creation of the comprehensive methodology of the Quadro-copter testing together with the proposal of the software solution and methodology of the drone categorization in accordance to the selected flight characteristics.

Global Navigation Satellite System has become part of our everyday life and our dependence on it has been increasing though various fields including aviation. The GNSS signal transmitted by satellites is being received as a weak signal, therefore it is susceptible to interferences. A several situations of GNSS interference recently occurred in the real operation causing the limitation of using procedures based on satellite navigation. In most cases, the source of the interference is a jammer placed in a lorry which is located on a road or a car park around an airport. Furthermore, there may be intentionally transmitted jamming signals for disabling the position determination of military vehicles in war zones. There is a need to ensure the alternative navigation system for situations of GNSS signal unavailability, as well as to ensure the time synchronization. A several concepts of alternative systems have already been designed, however, none of them was determined the global alternative GNSS backup system. The project concerns with validation of designed concepts from the sight of appropriate solution for needs of the Czech Republic. Moreover, it aims to create an original model for position determination based on position information exchange among aircraft. This model enables solution for position calculation outside line of sight areas of the terrestrial stations within the alternative concepts.

Operational safety is an important aspect of aviation and it is necessary to further success and development of aviation. A modern approach to safety management is based on proactive and predictive control methods. Aviation stakeholders typically operate with both approaches, however they are not able to profit from the potential of their integration. The integration of safety studies with the operational safety data leads to the development of smart instrument for optimum management of operational deviation. The creation of a conceptual model of the integration is needed for implementing the instrument. The solution is based on current methods and procedures used by safety engineering, the STPA (System-Theoretic Process Analysis) in particular. The project take use of Unified Foundational Ontology as an unifying means of contemporary conceptual models. The aim is to provide a model of the subject area that will allow the use of results for the integration of data in the software background for the Safety Management System. The resulting solution will be validated in cooperation with Prague Airport. The conceptual model will form the basis for designing and implementing solutions in other areas where safety studies are used.
