Skyguide enlisted the support of Frequentis Control Room Consulting in order to effectively analyse potential enhancement in their internal information streams to improve customer satisfaction and deliver the best possible service to customers. Skyguide manages one of the most complex and dense airspaces in Europe. The City-Pair flight route between Geneva and Zurich, with its very short airtime and close proximity to neighbouring countries, represented a major challenge when it came to delivering the best possible air navigation services to passengers. Demanding topographical and environmental restrictions added to the complexity.Frequentis Control Room Consulting (CRC) initially spent one week observing the workflows in the Skyguide control room, and interviewing major stakeholders, before delivering an overarching information stream map of a typical flight from Geneva to Zurich. Ten bottlenecks in the information stream were identified, which allowed solutions to be put forward. Frequentis Control Room Consulting bridges the gap between user experience and technical set-up. By adding Frequentis consulting services to improvement initiatives, customers can be supported in everything from optimisation to allowing new features and functionality to be implemented into their production environments without disruption. Frequentis' deep knowledge of safety-critical environments in various domains allows Frequentis consulting services to provide the required support ensuring maximised productivity, a safe technological environment, and an evergreen approach to support all phases of the customer's control-room lifecycle.
