“…For the specific TSS flight tests execution, two real vehicles have been involved: Ownship: EVEKTOR EV-55 – It hosted the TSS software running in the CCP and the TSS HMI on a PED in the cockpit. The aircraft was equipped with ADS-B IN device and was not cooperating with intruder in terms of manoeuvres execution, because the TSS, as clear from the previous section and emphasized in (Di Vito et al , 2017b, 2021d), does not require coordination of the manoeuvre with the conflicting vehicle. Intruder : EVEKTOR VUT100 Cobra – It was equipped with ADS-B OUT device and was not cooperating with ownship in terms of manoeuvres execution, as just emphasized. …”

“…The TSS benefits from the presence on-board of ADS-B IN receiver, able to collect the broadcasted information provided by surrounding traffic through corresponding ADS-B OUT devices. Based on the traffic info, the TSS performs its computations in real-time during the flight (at 1 Hz update frequency), in order to provide the pilot not only with consolidated traffic picture extending pilot’s situational awareness but also, and more important, with automatic support to pilot’s decision making, thanks to the TSS performed automatic elaboration of suitable conflict resolution manoeuvre, if and when possible loss of separation is detected by the TSS over a tactical time horizon (Di Vito et al , 2017b, 2021d).…”

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.

“…Adopting this airborne FR for airplanes in the transport category, that is classified according to EASA CS-25 or FAA's 14 CFR Part 25, can be considered a conservative approach, since the ADS analyzed in (Lerro and Battipede, 2021) is designed for SAT, which belongs to EASA CS-23 (Lerro and Battipede, 2021;Piwek and Wiśniowski, 2016;Di Vito and Torrano, 2017). Indeed, it is expected that EASA CS-25 classified airplanes are equipped with ADSs of a higher grade with respect to the EASA CS-23 classified ones.…”

This paper refers to the developments of the single pilot enabling technologies that are designed, implemented and validated in the Clean Sky funded project COAST (Cost Optimized Avionics SysTem). The target industry domain of such technologies is the aviation segment of Small Air Transport (SAT), referring specifically to commuter category vehicles (5 to 19 pax), under the EASA CS-23 regulation. Among the several technologies that have been designed, developed and demonstrated in flight, there is the Tactical Separation System (TSS), which reached TRL 6 in 2021 thanks to successful flight demonstration. It represents fundamental decision-making support system, able to assist the single pilot in the management of the separation task, under delegation of the separation responsibility to the pilot by the ATC. Nevertheless, in order to properly integrate and enhance the individual enabling technologies for single pilot operations, in the COAST project a unique Integrated Mission Management System (IMMS) is being designed. It constitutes a further technological advancement to support more effective and safe management of situations of pilot’s incapacitation during the flight, under single pilot operations, and a relevant step forward towards more autonomous aircraft. To support the IMMS implementation, therefore, the Tactical Separation System is currently subject to proper evolution, in order to include specific functionalities that will be needed as part of the IMMS. This paper outlines the main outcomes from the design and demonstration of the Tactical Separation System as individual technology. After that, it describes the IMMS and the specific role that the tactical separation functionality will play in such framework. Finally, the paper reports the evolved TSS version design currently ongoing in the COAST project, with specific focus on the implementation of the tactical traffic clustering functionality.
