“…The SA and CA functions are allocated on two different logical levels, since CA is considered as an emergency function that is activated only when an emergency event is raised, whereas, in tactical operations, the SA function is in charge of guaranteeing safe separation among aircraft. The functional architecture of the ASACAS system is reported in Figure 2 [14]. Figure 2.…”

“…Figure 2. ASACAS functional architecture [14] As indicated in Figure 2, the system receives, from the on-board ADS-B IN surveillance sensor, traffic position and velocity data about surrounding ADS-B OUT equipped aircraft, in order to predict future conflicts (intended as predicted loss of separation) and potential future collisions between ownship and surrounding traffic. The DAA system is supported by a DO-317 [24] Surveillance Processing application, aimed to perform the processing of the raw data provided by the ADS-B IN surveillance system, in order to allow their use by the conflict/collision detection system.…”

“…The intruder and ownship positions are reported with respect to a local reference frame centered in the initial position of ownship at the simulation start. In the real time tests here described, conventionally, the origin of the local reference frame corresponds to the point where the handover procedure between the Safety Pilot and the Remote Pilot has been completed and, therefore, the Remote Pilot is operating the RPAS ownship [14].…”

“…Both the aircraft are performing straight and level flight towards their selected destination waypoints, so the geometry here considered leads to a loss of separation according to head-on encounter (to be noticed that, indeed, a lateral displacement of 500 m exists between the vehicles, which in any case leads to loss of separation condition, due to the circumstance that the nominal separation volume centered in the intruder has 0.5 Nm radius, so it is greater than the 500 m displacement). This Separation Assurance test has been preliminarily examined in the reference paper [14] and is here addressed once again in order to provide its deeper analysis, also with respect to the additional exemplary Separation Assurance test 2 here reported.…”

“…A description of the real-time demonstrations carried out in RAID has been provided in the reference paper [14], which was aimed to represent an overview of the project contents but was not specifically devoted to the specification of the features of the integrated ADS-B based Automatic Separation Assurance Collision Avoidance System (ASACAS) designed by CIRA, the Italian Aerospace Research Center, that has been demonstrated in the project. The aim of this paper, therefore, is to report with more details and more specific focus the outcomes and findings from the real-time demonstrations carried out in the RAID project, so complementing and extending the previous reference paper [14]. Of course, being this paper limited to real-time demonstration results description and discussion, it does not cover the flight demonstration results, which will be addressed in future works.…”

Remotely Piloted Aircraft Systems (RPAS) are increasingly becoming relevant actors flying through the airspace and will assume much more importance in the future perspective. In order to allow their safe integration with manned conventional traffic in non-segregated airspaces, in accordance with the overall Air Traffic Management (ATM) paradigm, specific enabling technologies are needed. As well known, among the enabling technologies identified as crucial for RPAS integration into the overall ATM system, the Detect and Avoid (DAA) technology is fundamental. In the meantime, to support extended surveillance, the universal introduction on-board of aircraft of cooperative Automatic Dependent Surveillance – Broadcast (ADS-B) is increasingly implemented, having the potential to allow coverage of the whole airspace also in remote areas not usually covered by conventional radar surveillance. In this paper, the experimental results are presented and discussed that have been obtained through the real-time validation, with hardware and human in the loop (RTS-HIL) simulations, of an automatic ADS-B based Separation Assurance and Collision Avoidance System aimed to support RPAS automatic operations as well as remote pilot decision making. In the paper, after an introductory outline of the Concept of Operations (ConOps) of the system and of its architectural organization, while also providing basic information about the main system functionalities, the description is reported of the tests that have been carried out and the obtained results are described and discussed, in order to emphasize the performances and limitations of the proposed system. In particular, not only the quantitative performances obtained are reported and commented but also the feedbacks received by the pilots in order to improve the system are described, for instance in terms of preferred typology of conflict resolution manoeuver elaborated by the system.

Purpose This paper aims to describe the advancements of the activities that have been carried out, in the Cost-Optimized Avionics SysTem (COAST) project, to complete the design and in-flight demonstration of the Tactical Separation System (TSS), which is an automatic support system to the pilot’s decision-making, onboard on small air transport (SAT) vehicles under single pilot operations, in the separation management. Design/methodology/approach In the framework of the Clean Sky 2 funded project COAST, some enabling technologies for single pilot operations in the EASA CS-23 category vehicles are designed and demonstrated in flight. Among the relevant flight management technologies addressed in the project, the specific one devoted to the real-time support to pilot’s decision-making in maintaining the vehicle self-separation is the TSS, designed by the Italian Aerospace Research Centre. Findings The TSS design started in the year 2016 and has been completed in the year 2021 after successful in-flight demonstration in the dedicated flight test campaign. The system has been validated by means of several simulation campaigns and finally demonstrated its effectiveness in providing its intended functionalities (situational awareness, conflict detection, conflict resolution) to the pilot in real flight trials, involving the presence of real conflicting aircraft. Originality/value The TSS contributes enabling the implementation of single pilot operations in CS-23 category vehicles, thanks to the possibility to support the pilot with provision of consolidated traffic picture, detection of conflicting surrounding traffic and suggestion of suitable conflict resolution manoeuvre real-time during the flight, through dedicated human–machine interface designed on purpose. The TSS supports the new separation modes that are envisaged in the future SESAR ATM target concept, with particular reference to the possible delegation of the separation responsibility to the pilot.
