This area contains all expertise in relation to managing arrival, ground and departure traffic. It ranges from high level concepts to specific operational procedures and tools.


One of the major bottlenecks in the air transport system is the traffic on and in close vicinity of airports, specifically at hub-airports. Many airports have no possibility to expand their capacity by building new runways. Extra capacity should be found by optimization of the current operations. The overall goal is to increase punctuality and reduce delays and operational cost.


Typical activities in this field within AT-One are the investigation of local practices, develop new procedures, design support tools and validate the results. The work is oriented at providing practical results and solutions are implemented using prototypes. Operational procedures and tools are thoroughly tested and validated in our advanced simulators involving experienced Air Traffic Controllers and other professional staff. Of course, performing benefit analyses is an integral part of the work. After successful simulations, procedures and tools are tested by conducting shadow mode and life trials at actual airports.

AT-One also works on innovative long-term research to provide answers for the problems of tomorrow. Examples are highly automated Air Traffic Management systems and towerless ATC.
