A key aspect is the development of the controller workstation (CWP), which must be addressed carefully at an early stage. It represents the central environment for the controller, including the new visual surveillance system. A suitable HMI design can enable intuitive control functions and improve acceptance of the system. Intensive validation as part of a series of tests can ensure that the operational requirements for safe and efficient flight operations are met. DAS is familiar with important aspects of validation and can provide support with the operational experience gained from its own RTC projects.
