• If cabin data link systems can be securely connected to AIS domain flight data information infrastructure
on board such as IP data routers that already have access to flight data, then this combination would be
very well suited to performing flight data streaming in support of GADSS flight data recovery requirements.
Airlines are already downloading aircraft flight data post-flight over airport surface data links. Reuse of
these systems to redirect the data transmission over broadband links is logical. Only after ICAO establishes
performance standards can it be ascertained which data links can be used to meet the requirements.
• Since ICAO guidelines are that the solution for data streaming shall be performance based and be the
responsibility of air carriers, and shall not be prescriptive, it will be possible for airlines and/or aircraft
manufacturers to select from the combinations of available data acquisition, processing and routing
systems and available data link systems to build a solution that meets SARPs.
• In view of the above, further considerations on frequency spectrum allocations and bandwidth
requirements may be envisaged in order to properly examine the feasibility of reusing existing
infrastructure to support real-time flight data streaming, which covers the various existing aviation
satellite technologies and services (safety and non-safety purposes) as currently being provided to the
aviation community throughout the world.
