Connected Aircraft for Operational Awareness

To promote the digital transformation in aviation, a collaborative environment for sharing a richer set of information not only among ground-to-ground systems but also between flight crews and corresponding air traffic management service providers has been structured by the International Civil Aviation Organization (ICAO). However, due to the different requirements of operation, it is difficult to assure both high performance and cybersecurity for non-safety-critical and safety- critical applications by current air-to-ground communication systems. In this paper, not only the concept of connected aircraft, but also potential implementation challenges and additional functional capabilities to improve operational awareness are identified. Moreover, the practical development and the flight experiment related to the validation of IP data link service for connected aircraft is reported and analyzed.
