Project Paper 848 is being developed to support a secure networking infrastructure using a single broadband radio to serve multiple "domains" of Ethernet networks. This presentation examines a number of aspects leading to a candidate architecture. Presented in a joint session between AEEC Ku/Ka satcom subcommittee and AEEC Network Interfaces and Security subcommittee in Jan 2016.

ACARS Air Traffic Control messages have a clear safety mandate. ACARS AOC messages are not so clear. This presentation examines those aspects driving a safety designation. Route designation is applied to spectrum approved for safety and regularity of flight. The long term issue is whether ACARS is Aircraft Control Domain or Aircraft Information Systems Domain. Presented to FAA Performance-Based Aviation Rule-making Committee - Communications Working Group (PARC-CWG) in Feb 2016.
What is Safety Communications?
HF radios are still the alternative comms for oceanic and remote operations. HF performance limitations is leading to a barrier to reduced separation as enhancements like space-based ADS-B become available. The airplane has to carry a lot of HF equipment to facilitate reliable long-range communications. This presentation explores how using dissimilar satcom (Inmarsat plus Iridium) can support a major hazard (associated with loss of comms in compressed airspace).
Satellite voice uses a PSTN interface between the satellite network and Air Traffic Control facilities. Dialing is accomplished through pre-determined short-code (Air to Ground) or using the airplane ICAO address (Ground to Air). Work should begin to develop a more modern infrastructure that utilizes VOIP with integral context management for single-push dialing. This presentation describes these features.
