PUBLIC WIRELESS NETWORKS COMPLEMENT IMPERFECT LEGACY RADIO
Aircraft safety-critical communications are currently supported using legacy systems such as VHF, HF and authorised L-band satellite systems operating within dedicated and protected spectrum bands. In parallel, non-safety commercial communication systems relying, for instance, on public cellular network like 4G (soon 5G) or commercial Ku/Ka band satellite communication services, are increasingly used on aircraft for passenger internet browsing or pilot-airline interactions. These systems benefit from technological advances in the public wireless telecommunication markets, evolving toward enhanced and cheaper services, unlike legacy aviation communications.
Current aircraft safety-critical communication systems support current needs, but face constraints, and future replacement systems risk being unsuitable or too late to support unforeseen shorter-term safety-related disruptive aircraft operations. SESAR is exploring the integration of public network services and commercial radio links to develop a hybrid open/protected ‘hyper connected’ communications infrastructure for air/ground and air/air data to support future ATM and U-space operations.
The hyper connected ATM concept assumes that it will become acceptable and beneficial to use public non-safety commercial communication systems as a component of aircraft safety communications. This candidate solution aims to develop a concept of operations, identify use cases, capture high level requirements, and assess options of architecture to integrate commercial public network services into the future communications infrastructure (FCI).
