On the other hand, enhanced technologies (e.g. SATCOM) offer new link capacities and allow us to aggregate all these different kind of traffics on a single link. Up to now, each class of services has its own communication infrastructure, but it seems favorable to integrate them all on the same system for cost-saving purposes. Recent researches have shown
that the convergence to an aggregated air-ground data-based communication system is a trend for future aircrafts: [5] studied the feasibility of an hybrid aeronautical system where ATS, AOC, and APC traffics are mixed on the same satellite link.
