The small air transport (SAT) domain is gaining increasing interest over the past decade, based on its perspective relevance in enabling efficient travel over a regional range, by exploiting small airports and fixed wing aircraft with up to 19 seats (EASA CS-23 category). To support its wider adoption, it is needed to enable single pilot operations.

An integrated mission management system (IMMS) has been designed and implemented, able to automatically optimize the aircraft path by considering trajectory optimization needs. It takes into account both traffic scenario and weather actual and forecasted condition and is also able to select best destination airport, should pilot incapacitation occur during flight. As part of the IMMS, dedicated evolved tactical separation system (Evo-TSS) has been designed to provide elaboration of both surrounding and far located traffic and subsequent traffic clustering, to support the trajectory planning/re-planning by the IMMS.

The Clean Sky 2-funded project COAST (Cost Optimized Avionics SysTem) successfully designed and validated through flight demonstrations relevant technologies enabling affordable cockpit and avionics and supporting single pilot operations for SAT vehicles. These technologies include the TSS in its baseline and evolved versions, included in the IMMS.

This paper describes the TSS baseline version and the basic aspects of the Evo-TSS design. It is aimed to outline the implementation of the Evo-TSS dedicated software in Matlab/Simulink environment, the planned laboratory validation campaign and the results of the validation exercises in fast-time Matlab/Simulink environment, which were successfully concluded in 2023.

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.

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.

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.

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.

This paper promotes a critical approach to co-operative studies by contributing new theoretical insights. The aim is to propose a new view on the co-operative firm as a socioeconomic phenomenon embedded into the local contexts in which it is situated. Sociological and economic analyses have mainly explored the relationship between co-operative members and the organization, the economic performance of co-operatives or compared co-operatives with other firm types. Less attention has been given to the co-operative–territory relation, which can reveal insights into members' collective actions, a co-operative's origins from specific social groups or how they establish relationships with certain community stakeholders over others.

The paper begins with a literature review of academic studies that situate co-operatives in relation to community, with a focus on how social capital theory has been deployed to understand this relation. It then proposes a theoretical examination of two fundamental authors in the field of social capital theory: Robert Putnam and Pierre Bourdieu. Drawing on findings from the literature review and considerations derived from the theoretical dialog between Putnam and Bourdieu, the paper proposes a revised social capital-based framework for analyzing key relations and expected outcomes of the co-operative–territory relation.

Reconsidering the role of social capital theory for co-operative studies, this article unfolds a dual reflection. First, it underlines the necessity for research that more closely considers co-operatives' territorial relationships. Second, it critically interrogates and pushes forward social capital theory as a framework for examining the social relations that embed co-operatives and their capacity to activate territorial economies.

The paper highlights the necessity for a further examination of the co-operative–territory relationship. It presents an innovative framework for improving sociological understanding of co-operatives as organizations embedded into their local socioeconomic contexts.
