The planning of the entire operational transition from a conventional tower to a remote tower is based on the transition plan. This includes the planning and control of all important milestones with regard to installation, the establishment of new services and interfaces to existing systems as well as the acceptance and test series leading to the final commissioning. This allows important measures to be defined and potential risks to be identified. Extensive testing of individual systems and operating scenarios is essential for a high level of confidence in operational usability. Our experienced transition and change management is the key to the project’s success. Following the introduction of RTC in Germany, DAS is using its experience and knowledge to ensure a smooth transition.
