Airports: Balancing optimisation and expansion
Airports: nowhere else in the air transport system are the available capacities as limited and at the same time the subject of controversial political discussions. In the face of continually increasing demand, airport operators have only two alternatives: they can either optimise the utilisation of the available area as much as possible or they can expand the available capacities. The fast-time simulation by DFS offers an excellent basis for making this decision. The DFS fast-time simulation has already been used successfully to conduct analyses at major international airports such as Frankfurt, Moscow and Munich. At these large hubs, where the interests of airlines, air navigation services and apron management services conflict with each other, a key advantage of our simulation tool becomes apparent. In contrast to other tools, this simulation does not consider just the taxiing or just the airborne traffic. Instead, the gate-to-gate competence of the system makes it possible to simulate scenarios extending from the start of the final approach to the time where the aircraft is parked on a defined parking position. The degree of detail of the simulation can be adjusted as desired. De-icing routines, slow movement of aircraft with tractors and the characteristics of each taxiway segment and parking position can be simulated realistically. In addition, the simulation tool contains details of all relevant air traffic control procedures, such as approach and departure procedures and separation minima. It is thus possible to provide airport operators with well-founded recommendations within a very short period of time. This simulation has been used to solve various problems. For example, DFS examined the effects of a new runway and of a new terminal building for Frankfurt Airport. All operating procedures in the air and on the ground were simulated in detail. On the basis of a specified maximum delay value, it was thus possible to determine the optimum taxiway routing for a traffic sample forecasted for the year 2015 with about 2,000 aircraft movements per day and a coordinated capacity of about 120 aircraft movements per hour. This allowed the airport operator Fraport to prove the benefit of a planned major investment quickly and at an acceptable cost. A similar simulation was carried out at Moscow Airport without interruption of flight operations. Our airport simulations provide you with a basis for making decisions with respect to:
