Opis:: The article is devoted to the problem of decision support in a simulation environment prepared for the air traffic control service. The limitations resulting from the functionality of the airport have been presented. In addition, the “integration” problems resulting from the movement of aircraft on the apron have been presented. The article outlines optimization problems such as minimizing the total taxiing time, taking into account the waiting time for the start of the runway, minimizing the time elapsed from the first taxiing to the end of taxiing by the last aircraft or multi-faceted functions, including, for example, penalties for deviations from the schedule of take-off / landing operations, failure to keep the CFMU time slots, or for too long taxiing cycles. The article presents restrictions on taxiing of aircraft, integration with other airport operations, decision problems and applied algorithms, groups of restrictions on taxiing of aircraft, scheduled flight table, dependencies between individual operations, positioning of aircraft.

Opis:: The article refers to the problem of assigning the aircrafts to stops points on the apron. The aim of this paper is to develop the algorithm, which will be used to this assignment. The assignment problem of aircrafts to stops points is the complex decision problems, which refer to the problems of designating the minimal path in the graph. The assignment model was described, i.e. decision variables, constraints and the criterion function. Decision variables take the binary form and determine the connections between the elements of infrastructure of the apron, i.e. touchdown points, intermediate points and stop points. Constraints take into account the number of aircrafts in the given period, the number of unoccupied stop points. The criterion function determines the minimum driving time of the aircraft on the apron. In order to designate the routes in international transport the heuristic algorithm, i.e. ant algorithm was developed. The steps of building this algorithm were presented. This algorithm was verified in the C# programming language. The results generating by the presented algorithm were compared with the results generating by the random algorithm.

Opis:: 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.

Polska
Opis:: Civil air traffic in Poland is organized in accordance with international regulations provided by International Civil Aviation Organization (ICAO). Flight operations are performed in controlled airspace (CAS) or uncontrolled airspace. The division contains different approach to flight planning (FP) and group specific types of airspace users (AUs) and aircrafts types. Typically, General Aviation (GA) operations are placed in uncontrolled airspace while airline operations in CAS. This practice results from air operations types and aircrafts flight performance. GA includes sport, school, private transport or business flights and therefore the uncontrolled airspace with its vertical border form the ground to FL 95 contains most of the GA operations. However, there is a part of GA operations performed in CAS according to Instrument Flight Rules (IFR). The aim of the work is to describe the structure of domestic GA operations in IFR flights in CAS of Poland. Using the archival air traffic data from previous five years (2012-2016) the defined subject was analysed. In the first part, the aircraft fleet is presented. It contains the description of aircrafts types with relation to route distances, number of flights, propulsion type and wake turbulence category (WTC). In the second part, the network of defined air traffic was shown. It contains data about departure and destinations airports, the airports loading, month statistic of flights and trend in traffic changes. The traffic data are obtained from Eurocontrol database Demand Data Repository (DDR2) and using the NEST Eurocontrol software. The article arose during author’s traineeship in Eurocontrol within a framework of SESAR 2020 project, PJ.06-02 solution. Presented analyses are useful from the FP point of view since the PJ.06-02 solution refers to “Management of Performance Based Free Routing in lower Airspace” and need to consider the features of every airspace users.

Opis:: Poland – according to ICAO requirements, is obliged to conduct analyses of the coefficients adopted to assess the level of safety in civil aviation. They are carried out on the basis of the data contained in the ECCAIRS database. The authors have processed the data contained in this database by analysing them using various criteria (ICAO aviation occurrence categories, flight phases, different airports) to test the methodology of the safety indicators values forecasting and setting their “warning levels”. Exceedance of these levels could be a signal for taking preventive action by the relevant competent aviation authorities. The proposed method is based on the assumption that the determined parameters are governed by normal distribution rules (Gaussian). Parameter values calculated based on real data from 2016 were compared with those predicted a year earlier. It was found that the factors for different events have increased significantly - above the calculated warning levels, particularly for general aviation. The results of this analysis may support competent aviation authorities' decisions in areas where safety risks are most critical.

Opis:: In aviation, aircraft ground handling defines the servicing of an aircraft while it is on the ground and (usually) parked at a terminal gate of an airport. Ground handling operations include many activities: passenger handling, ground transport, assistance in blocking the aircraft and delivery ofreąuired equipment, loading and unloading of the aircraft, including provision and operation of required equipment, as well as transport of the crew and passengers between the aircraft and the terminal, transport of luggage between the aircraft and the terminal, catering. This paper presents a fragment of an analysis of the elementary operations performed at the apron and presents model of ground handling at the airport and stochastic analyses. The method of sohing the problem is based upon an analysis of the actual airport operations. During the investigation different ground handling processes schemes and elementary operations identified at the apron were analyzed. Random parameters of the duration ofeach action at the apron were identified. The focus was the problem of increase airport capacity for the ground airport operations. Problem of airport capacity is specifying as airside and landside. The authors present short description of method. It is present ground handling model and some of results of simulation.

Opis:: A problem of influence of traffic produced turbulence on car exhaust pollutant concentration in some road areas is examined in the paper. The linear source model has been applied in order to describe the emission of pollutants. This model allows defining a relationship between average vehicle speed and traffic intensity. The emission and dispersion of carbon monoxide have been analysed for four different configurations of roads (including one for flat terrain). A numerical model of wind field and car exhaust pollutant dispersion has been used in order to analyse the impact of traffic turbulence on dispersion conditions. The emission intensity for the linear source has been obtained using INFRAS database. The results presented shows, that omitting of traffic turbulence causes overestimation of calculated pollutants concentration. This is some kind of evidence that the traffic induced turbulence should be taken into account in air quality modelling especially close to the road areas. In particular the relation between average traffic speed and traffic intensity, domain area and cases considered and carbon monoxide concentration calculated for different cases are presented in the paper.
W pracy przedstawiono wyniki numerycznej analizy wpływu turbulencji generowanej ruchem pojazdów na wartości stężeń zanieczyszczeń w pobliżu ciągów komunikacyjnych. Do modelowania emisji związków szkodliwych spalin przyjęto koncepcję źródła liniowego o natężeniu zależnym od średniej prędkości ruchu pojazdów. Analizowano emisję i rozprzestrzenianie się tlenku węgla, rozważając przy tym cztery różne układy komunikacyjne, w tym jeden w obszarze niezabudowanym. Do analizy wpływu turbulencji generowanej przez pojazdy na warunki początkowe rozprzestrzenia się zanieczyszczeń pochodzenia samochodowego wykorzystano numeryczny model pola prędkości powietrza i dyspersji zanieczyszczeń. Natężenie emisji dla źródła liniowego obliczono przy wykorzystaniu danych z modelu INFRAS. Uzyskane w pracy wyniki wskazują, że pominięcie dodatkowego źródła energii kinetycznej turbulencji jakie stanowią pojazdy w ruchu, prowadzi do zawyżania obliczanych stężeń zanieczyszczeń. Świadczy to o konieczności uwzględniania turbulencji generowanej ruchem pojazdów w badaniach oceny jakości powierza, zwłaszcza wokół ciągów komunikacyjnych. Zależność średniej prędkości ruchu pojazdów od natężenia ruchu, obszar dyskretyzacji i rozważane warianty obliczeniowe oraz obliczone rozkłady stężenia tlenku węgla dla różnych wariantów są przedstawione w artykule.

Opis:: This paper presents an overview of the most important requirements and recommendations of international organizations for the area of LNG terminal under construction in Świnoujście. These recommendations should be considered when planning safe traffic and manoeuvring of ships in port approaches to the Port of Świnoujście and to the Outer Port of Świnoujście. The approach area to the new terminal is located on shallow waters. Up to the present moment the fairway, anchorages and seamarks have been used by vessels of smaller size. After the construction of the new port with an LNG terminal it will handle the greatest LNG carriers. To ensure their safe entrance to the port, the fairway should be prepared with sufficient width and depth, with navigational aids. It is also necessary to prepare appropriate emergency anchorages and places where the vessels can return in case further voyage is dangerous. Additionally LNG cargo is very dangerous, because of this there is a compulsory to introduce of the highest safety standards, both in the design of the approach area and the application procedures for ships traffic. In particular, fairways and port canals, Under Keel Allowance, air draft, turning basin, vessel traffic services (VTS), traffic separation schemes (TSS), moving safety zone, and required speed limit are presented in the paper.
