The integration of remotely piloted aircraft system in non-segregated airspace requires a significant effort and new methodologies to underway this challenge. This paper develops a methodology to assess the impact of remotely piloted aircraft system integration by applying safety metrics in tactical planning. This methodology builds five modules to simulate remotely piloted aircraft system introduction in a conventional-aircraft schedule: Base scenario, path modelling, conflict detection, temporary-blocking window and safety metrics. The safety metrics quantify the safety state of the operation by the number of conflicts, the conflict severity and the airway availability. This last safety metric represents a step forward in the decision-making process because it provides the airway risk-suitability to integrate remotely piloted aircraft system. Moreover, the temporary-blocking window underlies the airway availability metric. This concept provides temporary restrictions to the integration of remotely piloted aircraft system depending on the entry times of the conventional aircraft. Finally, this methodology is applied in an air traffic volume of the Spanish upper airspace. Different simulations were performed by introducing remotely piloted aircraft system covering every airway of the airspace. Results provided the temporary-blocking windows that specified the temporary restrictions to remotely piloted aircraft system introduction as a function of the airway flown by the conventional aircraft. Furthermore, the methodology appraised the airway availability characterising the airways depending on the risk impact by the remotely piloted aircraft system.

Abstract The paper presents the technologies currently available on the market in the field of anti-drone systems (C-RPAS -Counter Remotely Piloted Aircraft System). These include technologies with the help of radar, audio interception systems or via infrared and electro-optical devices, which are limited in remote sensing. The purpose of this paper was to highlight the multitude of factors that can influence the main mission of C-RPAS systems, the detection. Without detection the other features of a C-RPAS system could not be applied. I used specialized documents and studies, but also comparative analysis as research methods. The results of the study confirmed to me the hypothesis that anti-drone systems use in combination, one or more of the technologies (to detect, to recognize, to identify, to locate, to block, to capture or to destroy the drone). The first four (the detection, the recognition, the identification, the localization) are in the basic configuration for any C-RPAS system. In the future, there will be a challenge (for the producers of C-RPAS systems), the capture of the RPAS, especially the military ones. It is also important to prepare the operators / beneficiaries for such systems. They can influence the effectiveness of drone combat missions.

Research Service

On June 1, 2019, new rules for flying a Remotely Piloted Aircraft System (RPAS) or “drone” in Canada came into effect, requiring drone pilot certification to operate any drone between 250 g and 25 kg. In response to new regulations and the needs of our researchers, the Ryerson Library has initiated the development of a research service dedicated to supporting the use of drones and 3D modeling technologies. Before cancellation due to the Covid-19 pandemic, the joint CAG/CCA/CARTO-ACMLA conference - CAG 2020: Resilience on a Dynamic Planet - provided a national venue to showcase our progress to date. This report will summarize our workshop content and outline existing collaborations and future directions for our research and service.

Abstract Background Although there is currently little research data to support the contention, concerns have been raised about possible traumatic stressors inherent to Remotely Piloted Aircraft System (RPAS) operator roles. Factors such as exposure to visually traumatic events compounded by long working hours and blurred boundaries between military and civilian life have been cited as potential stressors. Robust research into the well-being of RPAS operators is scarce and mostly samples US personnel. Aims To provide mental health and well-being data relating to UK RPAS operators. Methods UK RPAS operators completed mental health questionnaires to assess levels of post-traumatic stress disorder (PTSD), anxiety and depression symptoms, alcohol use and occupational functioning. Respondents were also asked about work patterns. Results Forty-one per cent of the sample reported potentially hazardous alcohol use. Ten per cent met psychiatric symptom criteria for moderate or severe anxiety, and 20% for moderate depressive symptoms. While there were no cases of probable PTSD, 30% of the sample reported sub-clinical PTSD symptoms likely to impair occupational functioning. Overall, 70% of the sample reported that psychological symptoms significantly impaired their functioning. Conclusions Compared to UK military sub-groups, RPAS operators were not at increased risk of mental health problems. However, a high proportion of the sample reported significant functional impairment, which has not been explored in other comparable studies. The most frequently highlighted work-related stressors were timing of RPAS work and operator shift patterns.
