In non-segregated airspace, the link between ATC (air traffic control) and UACS via Unmanned Aircraft (UA) is called ATC relay and it will be required to relay ATC and air-to-air communications received and transmitted by the UA. For communication with ATC, the UA uses the same equipment as that of the manned aircraft. There are two types of communication between UACS and UA via ATC i.e. the downlink bringing the ATC information from the UA to the UACS (Unmanned Combat Aircraft System) and the uplink from the UACS to the UA allowing the UACS to communicate with ATC. This type of communication is critical from the point of view of the safety of the controlled airspaces, especially in areas with a high density of aircraft and terminal in approach. In this case, Future ICAO standards are of immense importance for these kinds of communication.
