Over a century has passed since humans took to commercial flying. Traditional safety practices have worked well but the last decade has seen the need for an updated understanding of ATM safety. The modern safety views are complementary to the traditional ones but are also a new way of understanding and enabling safety practices. This master thesis report presents a comprehensive review of the sources chosen from literature to better understand how a complex sociotechnical system, such as ATM, would operate. Certain selected coordination aspects will be the focus of this master thesis and will be used to model and analyse an ATM case. The ultimate aim of this research project is to add to the growing body of knowledge in the field of ATM safety, to make flying increasingly safer and to enable a complex system to be resilient.
