Rising awareness of aviation noise's health and annoyance impacts does not coincide with the industry's sustainable transition which is primarily driven by climate change. While electrification and sustainable fuels are seen as solutions, current strategies often encourage aviation sector growth including airport and traffic expansion. National ini...

Commercial deployment of maritime autonomous surface ships (MASSs) is close to becoming a reality. Although MASSs are fully autonomous, the industry will still allow remote operations centre (ROC) operators to intervene if a MASS is facing an emergency the MASS cannot handle by itself. A human-centred design for the associated emergency response sy...

Three key challenges to a whole-system approach to process improvement in health systems are the complexity of socio-technical activity, the capacity to change purposefully, and the consequent capacity to proactively manage and govern the system. The literature on healthcare improvement demonstrates the persistence of these problems. In this projec...

To perform as intended, firms are divided into work functions that contribute to the behaviour-shaping constraints under which individuals build their skills, knowledge and networks. These in turn provide a specialized perspective on organisational structure and culture. In a mixed methods study involving interviews and statistical analyses, we inv...

There is a strong and growing interest in using the large amount of high‐quality operational data available within an airline. One reason for this is the push by regulators to use data to demonstrate safety performance by monitoring the outputs of Safety Performance Indicators relative to targeted goals. However, the current exceedance‐based approa...

Landing aircraft create noise that disturbs residents living close to airports. One method to reduce such noise is to fly the final approach at a steeper glide slope than the normal 3.0 glide slope, thus increasing the distance between the source of the noise and the ground. If this is performed, there is a risk that the operational behavior of the...

Aviation, health care and financial services are increasingly stretched due to aspects that pose deep enduring systemic threats to our societies, challenging our ability to respond with commensurate socio-technical solutions. It has been argued that complex systems like these are intractable, defying generalisable analysis that could support predic...

The world of operational and work systems is changing not only because of increased commercial pressures to cut costs but also because the deployment of new technologies. Digitalization creates opportunities for new ways of organizing and managing existing work systems. Being able to achieve change and to design future systems are the core capabili...

Purpose The purpose of this study is to clarify business-to-business (B2B) firms’ strategies of social media marketing communication. The study aims to explore the factors contributing to the formation and adoption of integration strategies and identify who the B2B firms target. Design/methodology/approach A multiple case study approach is used...

Abstract The purpose of this paper is to explore turnaround performance as a resultant from both Collaborative Decision Making (CDM) processes and collaborative measures. This paper presents how CDM operates in the Turnaround Process (TAP) to propose a new method for managing the collaborative turnaround performance of all actors by predicting the...

The rate at which accidents/incidents occur within the Air Transport System (ATS) has remained consistent over the past two decades (European Commission, 2016). If such a rate is maintained and the ATS grows as expected (AirBus, 2013; Boeing, 2013), then the ATS may no longer be able to be considered ultra-safe. The purpose of this work is to devel...

The EU Vision 2020 sets a goal of reducing the air travel accident rate by 80%. Achieving this vision requires innovation and a different approach. PROSPERO (Proactive Safety Performance for Operations) is an EU FP7 project that will provide an advanced systemic methodology for managing the improvement process to help achieve that goal, as well as...

The key objective of this paper was to report on one of the industrial-based change case studies of the MASCA project (MAnaging System Change in Aviation—EU FP7, 2010–2013 ). This case study provides a systematic insight into one airport’s approach to their preparation for full implementation of Airport Collaborative Decision Making (A-CDM). An act...

All stakeholders within the aviation sector are currently facing immense system changes due to implications from the future Single European Sky concept and the new requirement for a Safety Management System (SMS). At the same time, the airline industry is under great financial pressure. So, there are no margins for failure to adapt and comply with...

Future air traffic management is facing major changes that will bring pilots and controllers, two professional cultures, closer with new technologies and collaboration. Earlier research on safety culture and organisational change such as mergers and implementing new system designs have been rewieved to identify applicable implications for the futur...

This paper reports on flight operations research, conducted as part of the work requirements for the Flight Operations Strand of the Human Integration into the Lifecycle of Aviation Systems (HILAS) project. Specifically, it presents a provisional framework for a suite of integrated Flight Operations tools developed in this research. It is anticipat...

The goal of this research is increased safety and human performance in aviation. Human errors are often consequences of actions brought about by poor design. The pilot communicates with the aircraft system through an interface in cockpit. In an alerting situation this interface includes an auditory alerting system. Pilots complain that they may be...

Extreme information overload during an aircraft accident was the origin of the project related. Interviews of pilots point at two major problems with the warning system of today: perceptual problems of too many auditory and visual signals and cognitive problems of understanding the alert messages. Experiments have shown that the existing sounds can...

Cognitive engineering is a multidisciplinary field, which must consider tradeoffs in various areas in order to reach a result that as a whole improves system performance without causing negative consequences. The goal of this research is improved ergonomics and safety. The auditory displays in many safety critical human-machine systems today have p...

A future framework of tools for capturing, analyzing and integrating data from both humans and aircrafts has been suggested in the ongoing HILAS project. These tools rely on reporting from the operators. In interviews and questionnaires pilots gave their views on reporting culture and possible blocks and barriers as well as enablers for increased p...
