Traffic organization in the airport area is one of the most difficult tasks for air traffic management services. This is due to the large number of aircraft performing complicated maneuvers in limited airspace. One of the key processes occurring in this area is the scheduling of landing aircraft. The aim of this study is to present the concept of implementation of a system for the evaluation of this process. The assessment method is based on determining the number of viable landings per unit time at a given aircraft schedule. On the basis of real air traffic measurements real landing aircraft schedules were analyzed. This shows that algorithms used by air traffic controllers in practice allow for a much smaller number of landings per unit of time than would result from the regulations. This indicates the existence of a large capacity to implement controller support systems in the process of aircraft landing scheduling.

Disturbances that occur in the course of transportation and storage tasks has been identified and analyzed. Disturbances occurring the most frequently in the ongoing processes of transport and storage have been selected. The article also shows possible ways of improvements of occurring disturbances. The article is of a practical nature.

The article presented part of the guidelines used for the modification of special purpose vehicle bodies. For example brand vehicles are details about the possibility of limiting the extension of the vehicle overhang, weight distribution, etc., and construction methods used in practice when extending the overhang of the vehicle. Describes the applicable rules for different technologies, ie. riveting, bolting, welding used in the modification of the frame.

This article presents data that concerns emission of nitrogen oxides, hydrocarbons, carbon monoxide and particles by different transport means. The road, rail and air transport were taken into account. The data published in references were analysed. To compare freight and passenger road transport emission expressed in grams per kilometre was presented. The emission in mg per passenger-kilometre enabled comparison of cars trains and planes in terms of air pollutant discharge. The data comparison revealed significant differences between transport modes. For aviation significant influence of flight distance on emission was observed. For flights running evenly with a parallel of latitude also the direction – according or opposite to the Earth rotation is significant.

This article is an attempt to approach essential issues in designing modern information systems. The key to successful information system is good design. A modern design requires looking from a number of different perspectives. Different people use different information in different contexts. These problems should be analyzed and requirements should be documented before solutions are designed and implemented. Satisfying the business needs is a baseline standard for information system.

The article outlines the calculation and production methods for stabilizer bars. Modern technological and structural solutions in contemporary cars are reflected also in the construction and manufacturing of stabilizer bars. A proper construction and the selection of parameters influence the strength properties, the weight, durability and reliability as well as the selection of an appropriate production method. The selection of the manufacturing process has a fundamental impact on the quality and durability of the stabilizer bars.

The article analyzes functioning in Kingdom of Poland, both military and civilian, water transport services since 1831. Some important activities of Russian Guard Equipage (Gvardiejskij Ekipaz) during period of 1831/1832 year and in years 1863 to 1864 were deliberated, as well as so-called. ”Flotilla of Warsaw”, patrolling Vistula river during January Uprising. Another described aspect of the activities of Russian water services was the control and management of some strategic bridges leading to tsarist citadels located in Poland. Analysis of the civil aspect of water transport surveillance in the Kingdom focuses on Banks of Vistula Service / Service of the Vistula River Rafting (dated as of 1837) and the Guidelining Service, erected between 1858 and 1865.
