Braunschweig, Germany – arosa is a generic system designed by Fraport together with delair Air Traffic Systems in order to manage and analyse the airport capacity. The complete turn-around process, including arrival and departure, is taken into consideration holistically in order to guarantee an optimal use of the total capacity.
Based on defined milestones, a target performance comparison is carried through continually for each process phase. Furthermore, prognoses regarding traffic development are calculated. Deviations or expected deviations are indicated to the users via intuitively applicable web frontends.
Essentially, arosa consists of two components. arosa capman provides quantitative values about the capacity of an airport, demand, punctuality and proposals for the operative concept. Its objective is to optimise the use of capacity, to open unexploited capacity reserves and to improve punctuality. The set observation delivers information regarding the possible number of movements in a time range, which are then allocated to specific flights by ataman.
arosa ataman analyses the phases of the so-called air-to-air process, determines target times and synchronises them with actual times. After considering arrival, departure and taxi costs and the available capacity, the flights are allocated to the applicable runways. The data is kept current by results being continuously and automatically updated to the system.
Due to the immediate analysis and control of ground movements arosa allows for an always up-to-date evaluation and, thus, for an optimum use of airport capacity.
arosa was successfully tested during its first trial-phase at Frankfurt International Airport. A second trial-phase is scheduled for October 2009.
