U-space airspaces may be established in controlled airspace, so that, the USSPs require the situational
awareness to provide the U-space services maintaining the acceptable level of safety. Thus, the Common Information Service Provider (CISP) is responsible for providing static and dynamic data to enable the provision of U-space services for the management of traffic of unmanned aircraft.
According to Implementing Regulation (EU) 2021/665 in its article 1, section 2(a) air traffic services
providers shall provide on a non-discriminatory basis the relevant traffic information regarding manned aircraft
that is necessary as part of the common information services. Then, since it is common information the CISP
makes these data available to the USSPs so that the UAS operators are notified about incoming manned traffic
that may eventually result in a conflict with the UAS flight trajectory.
The manned traffic information service supports its functionality by providing an interface so that the USSPs
receive all the manned traffic within the U-space airspaces in controlled airspace. The CISP publishes the
information through a topic and therefore, all USSPs subscribed to the topic receive the same dynamic data.
