Digitalisation holds great promise especially for complex ecosystems like the aviation value chain (aircraft, air traffic control – ATC, airports). By teaming up with their human counterparts (pilots, ATC operators, airport operators), digital assistants (DAs) can support the execution of tasks to ensure safe and efficient operations in complex scenarios. The project will develop three AI based solutions: an airborne digital assistant to support crew and single pilot operations; an ATC digital assistant to support more efficient and green tower operations; and an airport digital assistant will increase the level of automation in airports, enhancing safety and security for intrusion detection scenarios.
