“…The TSS architecture is summarized in the following Figure 1. The description of the individual components of the architecture can be found in the previous reference works, in particular in [19], and is briefly outlined in the figure itself in the yellow boxes. The first COAST flight test campaign has been successfully carried out, from 28 th June to 01 st July 2021, over the Kunovice International Airport (ICAO code: LKKU), in the Czech Republic, and has been coordinated by the COAST project leader Honeywell International (Czech Republic).…”

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.

Purpose This paper aims to describe the activities that are ongoing, in the Cost Optimized Avionics SysTem (COAST) project, to design an integrated mission management system (IIMS) to be used as support to the pilot and/or to act as a backup in case of pilot incapacitation onboard on small air transport (SAT) vehicles, under single-pilot operations. Design/methodology/approach The COAST project, funded by Clean Sky 2 programme, is developing enabling technologies for single-pilot operations in the European Aviation Safety Agency CS-23 category vehicles. Such technologies include specific tools that are designed as individual enablers for single-pilot operations and specifically address: the real-time support to pilot’s decision making in maintaining the vehicle self-separation (this technology is the tactical separation system [TSS]); the real-time support to pilot’s situational awareness about observed and forecasted weather conditions (this technology is the advanced weather awareness system [AWAS]); and the real-time management of emergency conditions due to pilot’s incapacitation under single-pilot operations (this technology is the flight reconfiguration system [FRS]). Based on the outcomes of the design activities of such individual tools, in the COAST project emerged the opportunity to proceed with the design of a further system, leveraging the individual tools and benefitting from their integration. Findings The IMMS design started in the year 2020 and the activities carried out up to mid-2021 allowed to define the concept of operations of the system, its high-level requirements (functional, interface and operational requirements) and the preliminary system architecture. Originality/value The IMMS contributes enabling the implementation of single-pilot operations in CS-23 category vehicles, thanks to the possibility to support, in normal operational conditions, the pilot’s decision-making and, in emergency conditions due to pilot’s incapacitation, the automatic flight management up to the safe destination.

“…• Flight Reconfiguration System (FRS) [2][3], an emergency flight path management system that is activated in case of pilot's incapacitation; it takes the control of the aircraft by means of an autopilot, computes an Emergency Flight Plan and leads to landing at a selected airport; • Tactical Separation System (TSS) [4] [5], an advanced self-separation system, based on ADS-B (Automatic Dependent Surveillance -Broadcast), to extend traffic situational awareness and to support the pilot's decision making, suggesting manoeuvres aimed to maintain required separation minima; • Advanced Weather Awareness System (AWAS) [6] [7][8], a system devoted to increase pilot's weather awareness providing updated data, generated on-ground and visualized on-board, regarding weather hazards (observed and forecast) occurring over the flight route. During the first years of the project, these three technologies were individually developed and successfully tested, at first in laboratory and then in flight during two demonstration campaigns held in 2021 and 2022, without any interaction between them.…”

The COAST (Cost Optimized Avionics SysTem) project, funded by Clean Aviation Joint Undertaking, works toward the realization of cost-effective key technologies for cockpit and avionics of Small Air Transport (SAT) aircraft. In 2020 the design of a new technology started, the Integrated Mission Management System (IMMS), devoted to automatically optimize the trajectory while considering air-traffic, weather conditions, terrain and obstacles. It is aimed to implement into a unique system the functionalities of Trajectory Planning, Flight Reconfiguration, Tactical Separation and Weather Awareness, benefitting from the integration and interaction on-board of three technologies, individually developed and tested in the first phases of the COAST project: Flight Reconfiguration System (FRS, managing pilot’s incapacitation emergency), Tactical Separation System (TSS, managing tactical traffic separation and enhanced situational awareness) and Advanced Weather Awareness System (AWAS, devoted to provide on-board updated weather data). The present work focuses on the last one and more in detail on the description of new functionalities introduced to the baseline AWAS system, already demonstrated in flight in 2021, in order to allow its integration in IMMS. Specifically, enhancements to the AWAS technology were required to integrate new input weather data and generate additional information, needed for IMMS purposes. These data are produced on-ground and sent through satellite link to the AWAS on-board segment, which has been updated to manage and exchange them with the other components on the aircraft. All the achieved progresses in the development of the evolved version of the AWAS system presented in this work will be demonstrated and tested in flight during a dedicated campaign planned in 2023 in the framework of COAST project.
