The main aim of the article is to bring the understanding of operational statistics of airports closer to readers. What is the essence of the execution and what belongs to them. For this article, we chose the Airport Kosice and present its operational statistics in a specific year. In the introduction are some business companies at the airport as well as the airport itself. The number of transported passengers as one of the most basic airport operation services is dealt with in the scheduled and non scheduled passenger transport for the chosen year. Finally, it is connected to the global overtaking operations of Kosice Airport. All of these indicators are graphically displayed for easier comprehension for the reader, the portions of the transported passengers for each selected transport segment.

The factor of the aircraft load or sometimes simply called the load factor is the rate of capacity of the airline. It is also known as the efficiency measure and is therefore the most commonly used estimate to describe the performance of the airline. Achieving high load factor is considerably important for the profitability of the airline, and it is interesting to identify factors that could influence the factors of the aircraft load. To describe the problem of load factor and airfare, we chose the Airbus A319 aircraft on the Bratislava (BTS) and Larnaca (LCA) routes. The data we used to calculate the individual indicators are based on real resources and give us a clear example of how the load factor affects the ticket price.

The Laboratory of Aviation Safety and Security at CTU in Prague has recently started a project aimed at runway protection zones. The probability of exceeding by a certain distance from the runway in common incident/accident scenarios (take-off/landing overrun/veer-off, landing undershoot) is being identified relative to the runway for any airport. As a result, the size and position of safety areas around runways are defined for the chosen probability. The basis for probability calculation is a probabilistic model using statistics from more than 1400 real-world cases where jet airplanes have been involved over the last few decades. Other scientific studies have contributed to understanding the issue and supported the model’s application to different conditions.

It is widely known that airports due to their character of everyday operations constitute a suitable environment for performing various safety related events. A large number of objects conducting series of operations within limited space and time increases potential for a particular accident or incident realization. According to their structure, accidents or incidents typical for airports in most cases combine mutually related negative influences that create preconditions and precursors (factors) for particular safety events. The aim of this paper is to provide a clear view on the organizational factors which represent integral elements of airport safety management and also to offer the solution for their better utilization for more effective identification and prevention of risk at the airport. The study takes into account different aspects of airport operations, management, decision-making processes, process monitoring, etc.

The first PBN approach procedures in Slovakia became operationally effective at Bratislava and Košice airports as of 5 February 2015. The article presents the results of EGNOS Safety-of-Life Service preliminary examination in eastern Slovakia, just before official introduction of these procedures. The practical examination includes static test and test flight made with Cessna plane taking off at the airport in Bidovce — LZBD (just 16 km from international airport in Košice) and passing a route along eastern border of Slovakia. In this region the performance of EGNOS could be unsatisfactory due to lack of RIMS stations to the east from there. The experiment was performed on October 13, 2014 in cooperation of the Air Force Academy in Deblin, the Department of Aviation of Technical University in Košice and University of Warmia and Mazury in Olsztyn.

Pierwsze procedury podejścia do lądowania typu PBN (Performance-Based Navigation) na Słowacji zostały wdrożone na lotniskach w Bratysławie i Koszycach 5 lutego 2015 r. W artykule przedstawiono wyniki wstępnych analiz serwisu Safety-of-Life systemu EGNOS we wschodniej Słowacji, tuż przed oficjalnym wprowadzeniem tych procedur. Badania praktyczne obejmują test statyczny oraz lot testowy wykonany samolotem Cessna z lotniska Bidovce-LZBD (oddalonego zaledwie 16 km od międzynarodowego lotniska w Koszycach) po trasie wzdłuż wschodniej granicy Słowacji. W tym regionie jakość systemu EGNOS może być niezadowalająca z powodu braku stacji monitorujących RIMS na wschód od tego miejsca. Eksperyment przeprowadzono 13 października 2014 r. we współpracy Wyższej Szkoły Oficerskiej Sił Powietrznych w Dęblinie, Wydziału Lotnictwa Politechniki w Koszycach oraz Uniwersytetu Warmińsko-Mazurskiego w Olsztynie.

For the good established landscape planning landscape protection and landscape management actions have to take into consideration the actual conditions of the landscape elements. Earlier we dealt with the stability of the landscapes (Kerényi, Csorba, 1996), recently started to investigate the most important factors, which are endangers the proper functioning of the landscapes. Results are calculated for 229 microregions of the country, which are elements of the official landscape hierarchy of Hungary described in the Cadastral of Microregions of Hungary. The average size of the microregions are 100-500 km2. There are certain factors among which some have already elaborated, and others are being worked on yet. Degree of ecological fragmentation of the microregions by roads, railway lines and settlements was determined during the last year. In the case of large settlements the extent of inner parts, traffic intensities of the roads was taken into account, while in the case of railroads it was taken into consideration whether railway lines are single or double tracked. Results were purified using a weighting, where the location of the protected natural areas compared to the situation of the given settlement, roads or railroads was taken into consideration. In the calculations it was taken into account as well that the agglomeration processes of the large settlements may restrict the ecological gates and corridors of the migration of plant and animal species. From the series of maps on natural threats on microregional level, the map of the hazards of drought is presented first. The map gives a definite answer to the question, in which microregions is profitable to establish irrigation systems; and how high is the uncertainty of the rate of their utilization. Global warming, however, may modulate the map resented here remarkably in the next decades. Microregions that have been classified into transition categories with moderate or medium level of drought hazard may fall into categories of serious hazard of drought in the future. A synthesizing map has been completed by summing the seven datasets of the indicator group of natural hazards and the weighting of the subsets. Landscape planning is strongly affected by tendencies of macro economy on the present land use structure. EU agricultural policies have just started to affect strongly on Hungarian land use structure, therefore attempts have been made in order to forecast their impacts. Present Hungarian land use structure has been compared to priorities of the EU. Prospective shifts in land use structure have been determined for the 35 regions of Hungary. According to the 8-10 factors mentioned above, we shall have a detailed database to evaluate the microregions of Hungary in order to characterize the most threatened landscapes, and the most dangerous impacts on the landscape functioning.

Application of remote sensing and other GIS methods in the subject of mapping mosquito breeding sites has not been premised accordingly. Despite the facts that the duration of field surveys would be shortened and the effectiveness of action plans would be higher with the supportance of computer modelling techniques. This work aimed to evaluate the applicability of digital elevation models and aerial photographs in the prediction of mosquito breeding sites. Relief analysis was carried out seeking depressions based on elevation models created with TIN and kriging interpolation methods. Spectral analysis was performed on aerial photographs to identify the patches of higher water content or moisture. The results show that terrain analysis can not give acceptable results due to its resolution and accuracy. Spectral analysis of normal (visible range) photographs can be a useful tool in predicting of breeding sites. On grasslands the verificitaion revealed 91% correct results.

Describing the environment with quantitative data is a new requirement in the environment related sciences which is the consequence of the developing computerbased methods. New requirements with new tools generated quick development in the measuring level: parameters turned to be measurable in several subjects. Landscape ecology as a young science has its own methods from the beginnings, but the quantified landscape geometry indices appeared only in the 1980s. Exploration of the landscape structure made necessary to elaborate those methods which were applicable to characterize the patches, corridors and the matrix of the landscapes. Nowadays we can find several landscape indices to quantify the geometry of landscape elements in patch and landscape level, but they are not used in the practice of the landscape management. It is shown in this paper that these landscape indices what novelty can mean in a sample area of Northern Hungary and what can be the practical side of their the usage. FRAGSTATS software was used to calculate landscape metrics. Principal component analysis was applied to reduce redundancy of indices and, based on the results, some of them was selected. Land use types and microregions were used as dependent variables in a discriminant function analysis. Both of them were identifiable with this method in several cases. Landscapes were clustered based on the characteristics of the landscape indices.

An opencast mine may cause negative effects in many ways. Landscape scarrings of opencast mines are harmful in aesthetic respect, engines, machineries and periodic blastings may cause notable noise loading which are injurious even if these mines are situated far from the settlements because the noise from the mines may disturb animals living in the surrounds (Kerényi, 1995, 2003, Barótfi, 2000). Besides the listed impacts the dust accompanied to the opencast mining cause the most significant load to the environment of these mines. In this study, the extent of dust loading is examined in the case of a North-Hungarian perlite mine. Milling of the exploited perlite is carried out in the milling plant located within the area of the mine in Pálháza which cause additional dust loading. Settling dust loading was studied by 22 measurement stations within a distance of 3 kilometres from the mine, during the installation of which even cover of the study area was aimed. Gathering of the dust samples were carried out monthly from August 2004 to July 2006 thus we have a two-year database. During the laboratory tests, the amount of insoluble and soluble dust fractions, altogether making up the total amount of settled dust, was determined respectively. In addition to the meteorological parameters having the most influence on the spatial distribution of the settling dust (i.e. wind velocity, wind directions and the amount of precipitation, air temperature, humidity and irradia-tion) that is why an automatic meteorological station was installed in the proximity of the mine, i.e. within the study area. It gave us the necessary meteorolo-gical data during the examination. Knowing that the most significant dust loading derives from the opencast mine we can not forget that periodically during the agricultural seasons from the arable lands and during the heating seasons through the chimneys additional dust might get into the dust-traps. To determine the origin of the dust in each dust-trap the dust samples were analytical examined as well. By the chemical composition of the samples we could find out how big roles the pollution sources outside the opencast mine played and hereby we could detect how significant the dust loading originated from the perlite mine is in its environment.

One of operative approaches within the main strategy, which is being used by an air organization to follow its mission and to reach long-term objectives, is safety management. It reflects the relative priority of selected objectives of the organization, regardless of time, which is the condition for long-term intentions. Future, expected results of the air organization are also partially determined by providing a permanent routine of various organization activities in the sphere of flight safety. An air practise also needs application of a system and situation approach to flight safety management to reach higher efficiency of partial activities and more complex organization reaction on inner or outer conditions. Permanent navigation training of pilots (especially pilots-cadets) presents one of the effective tool of successful flight safety management.

Zarządzanie bezpieczeństwem lotów jest jednym z praktycznych podejść używanych przez organizacje lotnicze w celu prawidłowego wykonywania założonych zadań i osiągnięcia długoterminowych celów. Ma ono bezpośredni wpływ na odpowiednie wartościowanie zadań organizacji, stanowiące ważne zagadnienie w określaniu celów długoterminowych. Przyszłość, oczekiwane rezultaty organizacji lotniczych są częściowo uzależnione od wprowadzenia stałych algorytmów postępowania dotyczących bezpieczeństwa lotów. Praktyka lotnicza wymaga także zastosowania odpowiedniego podejścia i systemu zarządzania bezpieczeństwem lotów, aby osiągnąć wyższą skuteczność w działaniach bieżących oraz bardziej kompleksową reakcję organizacji na czynniki zewnętrzne i wewnętrzne. Ciągły trening nawigacyjny pilotów (szczególnie podchorążych) stanowi jedno ze skutecznych narzędzi zarządzania bezpieczeństwem lotów.

Catalysts containing Ru on a TiO2- containing support or pure TiO2 were tested in the conversion of trichloro-ethylene (TCE) Increase of the TiO2 content of the support from ~20 to ~100%, or introduction of Ce as a second active component did not bring any advantage compared to the previously studied Ru-SM1 (Ru on ~20% TiO2 + 80% SiO2). Parameter tests were carried out in the presence of the latter catalyst. Total conversion of TCE was achieved at 450°C. Water vapor concentration practically did not affect the conversion of TCE. Higher space velocities have shifted the product, distribution towards HCl. Higher inlet concentrations of the model compound have resulted in decreased catalyst activity. 1,2-dichloroethane was easier to convert than TCE or tetrachloro-ethylene.

In our preliminary work we wanted to learn the effect of some metals on the product composition of the reformate in order to lower the aromatic content. Therefore we producted some trimetallic reforming catalysts by the modification of the reference catalysts is an industrially used 0.28% Pt-Sn/Al2O3 catalyst. The modification was carried out in aqueous solution of the added metal ions. The ions were reduced by the absorbed hydrogen. The produced five catalysts contain iridium, palladium, rhenium, tin and bismut as third metal besides platinum and tin. These catalysts were used in a test reactor under similar conditions as in industrial scale. The products were analysed by chromatography. In the light of the results it seems that the second metals lower the liquid yield. The C5+ product compositions is only slightly affected exept the bismuth modified catalyst.
