Abstract
Current Air Traffic Management (ATM) modernization programs face the challenge of integrating unmanned aircraft in non-segregated airspace. In order to manage these new airspace users as possible as manned aircraft, without any impact on Air Traffic Control (ATC) operations, regulators only consider operations of Remotely-Piloted Aircraft Systems (RPAS) able to fulfill many operational and technical requirements such as a Detect And Avoid capability. Nevertheless RPAS specificities, such as the criticality of the Command and Control (C2) link between the aircraft and the remote pilot, could prevent RPAS to act accordingly to future dynamic ATM processes when operating in a degraded mode. We present therefore in this paper a new communication architecture, based on the involvement of Air Traffic Controllers (ATCOs) in the management of RPAS in the case of a C2 degraded link or C2 link loss. We picture the expected benefits of this architecture with two critical scenarios based on a satellite latency and on a link loss. We finally describe the simulation protocol enabling us to assess different communication processes between ATC and RPAS.
