The Resilient Synthetic Vision for Advanced Control Tower Air Navigation Service Provision (RETINA) project is one of the selected Single European Sky ATM Research (SESAR) exploratory research projects on High Performing Airport Operations and it investigates the potential and applicability of Virtual/Augmented Reality (V/AR) technologies for the provision of Air Traffic Control (ATC) service by the airport control tower. The project assesses whether those concepts that stand behind tools such as Head-Mounted Displays (HUDs), Enhanced Vision Systems (EVSs) and Synthetic Vision Systems (SVS) can be transferred to ATC with relatively low effort and substantial benefits for controllers' Situational Awareness (SA). In doing so, two different augmented reality systems are investigated: Spatial Displays (SD) that, potentially, can be made to coincide with the tower windows and See-Through Head-Mounted Displays (ST-HMD). In this context the RETINA concept will enable the Air Traffic Controller to have a head-up view of the airport traffic even in low visibility conditions, similar to the vision currently provided in the cockpit with Head-Up displays. In the two-year project, the RETINA concept was developed, implemented and validated by means of human-in-the-loop simulations where the external view is provided to the user through a high fidelity 3D digital model in an immersive environment.
