The Concept of Tool to Support the Work of Air Traffic Controller in the Field of Aircraft Landing Scheduling in the TMA with Little Traffic

Recently, more and more are talked about the automation of air traffic control systems, which would allow relief work controllers. Methods or tools that allow for efficient and skillful management of air traffic are searched. The paper presents preliminary concept of the tool that would allow to schedule of aircraft landing at a given point and the scheduling is carried out taking into account the minimum separation between them. Separations are dependent on the types of aircraft. In addition, the program shows the routes by which the ship has to move in the area. The tool is dedicated to use in the TMA with little traffic, however, there are conducted further work, which would allow its use in sectors with far more traffic.

Pre-departure sequencing method in the terms of the dynamic growth of airports

The increase in air traffic requires organizational changes at the airport and near the airport. To ensure appropriate airport operating efficiency, it is becoming necessary to provide unobstructed flow of information between all parties involved in the process. Common decision-making process regarding operations carried out at an airport, based on legible information, may contribute to faster and more precise prediction of sequence of events. This article aims to present pre-departure sequencing method in the terms of the dynamic growth of airports. This method dynamically defines current sequencing of departing aircraft with consideration of time required to maintain minimum separation between subsequent take offs and evaluates runway occupancy regarding planned arrivals. Developed method uses criteria of reduction maximum delay on one handling position, which is starting runway in use. It is carried out by sequencing tasks, in accordance with non-decreasing requested times of completion. Greedy algorithm has been used to define sequence of carrying out take off operations based on the earliest possible time of the departure. Faced with dynamic growth of airports, this method may contribute to improvement of predictability of events, and thus facilitate proper decision making, which will allow managing airport traffic smoothly and without unnecessary downtimes.

Analysis of the Process of Merging Air Traffic Streams. Case Study of TMA Warsaw

Air traffic in the terminal area is carried out in accordance with the defined procedures, in the case of landing aircraft − Standard Arrival Procedures (STAR). Due to the fact that aircraft arrive from different directions, and landings take place on one direction of the runway, it is necessary to merge all traffic streams in a single queue for landing. STAR procedures define merging points. Current traffic conditions and economic factors indicate the necessity of dynamic modification of these points. Available telematic means allow for the effective implementation of this task. The aim of this paper is to analyze the schemes of merging air traffic streams on the example of the terminal area TMA Warsaw. It is focused on the search for the impact of the selection of merging points on the quality of the landing queue. For modelling of the process of merging air traffic streams at TMA Warsaw we used coloured, hierarchical and priority Petri nets. The estimations of the time of landing sequence execution were obtained. This time is the basic parameter of the landing queue evaluation. As a result of simulation tests, its dependence on the selection of streams merging points was identified. It has been found that the simplification of the merging procedure reduces the execution time of the sequence of landings. In further stages of the research, it is planned to develop an algorithm for selecting such points that lead to obtaining an aircraft landing queue with the most favourable properties.

Idea of Sustainable Development of Transport with Special Reference to Air Transportation

The idea of sustainable transport is an important aspect with reach beyond countries of the European Union. Opinion of the European Commission defines conditions that should be fulfilled in order to achieve certain goals. Transport should be the same for the current and future generations, safe and without risks to human health or natural environment and provide communication accessibility. Moreover, to guarantee efficient operation, there should be available choice of means of transport and their integration with other options in proximity of an airport. This chapter presents an important matter of air transport integration with other means of transport. It puts a thesis that different means of transport must cooperate to be included in the system of sustainable transportation, with special attention paid to air and railway transport. It was noted that aim includes definition of air transport role in integration with other means of transport.

IDENTIFICATION AND ANALYSIS TAKE-OFF AIRCRAFT OPERATIONS

Air transport plays a major role in the development of world economic activity and remains one of the fastest growing sectors of the international economy. One of the key elements that contribute to the maintenance of civil aviation development is to secure safe, efficient and environmentally sustainable means of transport, at the global, local and regional level. At airports communication air operations take place at intervals of tens of seconds to several minutes. A very important operation that the aircraft has to perform before coming to a safe standstill is take off. One of the most important operation is take off the aircraft. Security is an integral factor in determining the movement of the aircraft. The paper contains identification and analysis take off aircraft operations. The paper presents an analysis of the take-off operations including the rejected take-off. It is used in the analysis of the operation-taking place at the aerodrome of computer tools and methods. The result is the mathematical models form the basis for computer simulation. The aim of the article is modelling of the various stages of launch operations and identify basic models of these steps based on the parameters recorded by the flight data recorder aircraft. Constructed models imitating actual aircraft operations in the vicinity of the airport, will could be used in the practice of aviation.

THE PROJECT OF ADAPTATION OF AIRPORT TO EXECUTING THE IRREGULAR SERVICE OF AIRPLANE AIRBUS 380

The aircraft Airbus A380 is the biggest aircraft in present time. Many airports need to adapt their airside infrastructure. The main duties concerns upgrading runways, and taxiways, relocating taxiways and even relocating aircraft stands and buildings to provide sufficient wings clearance. There are many hubs in the world, which must rebuild elements of infrastructures for A380. Besides these large hub and main base airports, there are other airports around the world that will experience A380 operations. The operating frequency could be either on regular basis, such as one or two scheduled arrivals a day, but also may be a much lower frequency such as for a flight diversion. Such diversions could be either due to the unavailability of the destination airport (because of weather or operational issues) or because of an in-flight emergency. It is in the interest of in-flight safety to have a reasonable number of alternate airports and runways available in addition to the scheduled ones. Aircraft operations regulations make a distinction between destination alternate aerodromes, other alternate aerodromes required to be adequate (e.g. in JAR-OPS 1) and in-flight diversion aerodromes. For those alternate airports, large-scale changes to their existing airside infrastructure would be financially excessive and never be economical. On the other hand, especially in the case of a filed alternate, a minimum should be done to properly handle the aircraft and its passengers. In paper is presented necessary requirements to service of airplane the Airbus A380. It is presented on examples of Chopin’s airport in Warsaw. Service of this type of airplane requires adaptation of parameters of runway, taxiway and ground operations.
