City-ATM
Concept for future air traffic management (ATM) in urban airspace

To deal with the question of how a future airspace management system for unmanned and manned airspace users, especially operations in urban areas could look like, the German Aerospace Center has started the City-ATM Project at the beginning of 2018. It will address a variety of constraints to ensure safe and efficient integration of new airspace users. These airspace users can be very diverse and, in addition to VFR air traffic, also include others such as personal air vehicles (PAV), cargo UAS, parachutists, weather balloons or prioritized air traffic, such as rescue helicopter. In addition to aspects of different size, performance and abilities, additional requirements with regard to protected flight areas (so-called geo-fencing) or favored, risk-minimized routes must be taken into account in a U-space concept.

Project description

The City-ATM project will develop a concept for future air traffic management (ATM) in urban airspace, which will enable safe and efficient integration of new airspace users (such as unmanned aerial vehicles and air taxis). This includes the definition and validation of operational and technical concepts for airspace management, information provision, traffic flow control and monitoring, as well as CNS-infrastructure. Based on these concepts, a simulation and demonstration platform for urban ATM will be developed. This come along with the development of a concept of operations, the definition of requirements and framework conditions for the future ATM system as well as the considerations on the technical feasibility for users to operate safely in these environmental conditions.

Density-based airspace management

The target system is intended to enable and support flight testing within the developed City-ATM, initially in simulated - later real, but delimited - airspace. The aim of the project is also to bring together relevant stakeholders (such as UAS manufacturers, UTM system providers, aviation authorities and users) to develop a secure and efficient overall solution for the U-Space. The City-ATM project started on 1 January 2018 and is managed by the Institute of Flight Guidance.

City-ATM project - Safe integration of drones in the urban environment
DLR carried out the City-ATM project to lay the foundations for future airspace management in urban areas, in which new and conventional air traffic participants operate safely together. The video shows all three phases of the project, which was completed at the end of 2021.
Drone operations and hazards in City-ATM Phase 2
In phase 2 of the City-ATM project, complex flight tests with several drones were carried out at the National Experimental Test Center in Cochstedt in autumn 2020. This demonstrated in an exemplary manner how several drones can be safely handled in the event of sudden hazards and emergencies in an urban environment.
Autonomous drone operations in dense traffic in City-ATM Phase 3
In the third and finale phase of the City-ATM project, traffic scenarios were tested in which a large number of differently equipped drones are operated together and without conflict in one airspace. The tests were carried out with real and virtual drones at Cochstedt Airport.
