The negative impact of air incidents and emergency situations results from the leakage of liquids into the soil and water and the leakage of flue gases and combustion products of aircraft structural materials into the air during fires. This article deals with air pollution caused by the combustion of composite materials commonly used in general aviation. Samples of composite materials of aircraft registered in the Czech Republic were selected. These samples of composite materials were tested for flammability, according to ISO 5660-1:2002 Reaction to fire tests—Heat Release, smoke production and mass loss rate (ISO—International Organization for Standardization). Total smoke release and total oxygen consumed were assessed in this study, both of which have a significant impact on air quality in the case of an air incident. Based on the results of the research, differences resulting from the diversity of the structures of the tested composite materials were found. The most hazardous composite material was evaluated from the point of view of its impact on air quality during combustion.

Accurate navigation systems allow us to optimize the trajectory of flying objects and thus solve environmental problems in aviation and their impact on public health. In this paper, we present one of the methods of assessment of accuracy and resistance to interference of distance-measuring equipment (DME). By using computer technology, the method enables us to determine the potential but also the real error measuring the distance of the flying object from DME. The credibility of the respective results of the solution on the task of DME optimal rangefinder synthesis depends on the accuracy of the previous data used, i.e., mathematical models of the respective flying objects flight dynamics, useful signals, and their parameters and interference. DME systems have an impact on air transport safety, and therefore the impact of interference on their operation must be investigated.

Due to maintain the flow of the check-in process of air passengers, it is essential that services that ensure this process have been carried as quickly and effectively. One of the major current problems in this area is the efficiency of clearance of a large number of passengers over the check-in counters. By the gradual development of so-called self check-in services eventually delegate some activities in check-in process to passengers and the entire clearance process to speed up. In this article the authors deal with current state of the use of self check-in services in the world and predict the expected evolution of these services in the future. Subsequently, the authors present a new design of self-service kiosk and graphical user interface (GUI) of application such self-service check-in kiosk based on the analysis of the functions and features of similar solutions available on the market and with considering all currently known IATA requirements and the criteria relating to disabled passengers in order to lighten the load check-in counters and thereby accelerated the clearance of the passenger at the airport. The aim of the authors was to create a cost competitive solution offering such new features and services that do not offer other solutions, with an emphasis on improving the efficiency of the check-in process of passengers at the airport.

Aviation and climate change are often associated. The effects of climate change have increasing impact on the safe operation of airports. Due to both climate and weather conditions changes, airport winter maintenance is a significantly important activity of airports, especially in areas where a harsh winter season is expected. Continuous optimization of airport winter maintenance processes is necessary. The aim of this article is to present a possible way to optimize maintenance processes using simulation tools. The team of researchers identified key factors that are necessary for the application of the optimization. The article presents a procedure designed for safe handling of one of the model situations in winter maintenance of airports. The model of simulation defines critical points in the maintenance procedures designed for maintenance optimization using the data obtained from an international airport. Based on the determination of critical points of the maintenance procedures processed using a Gantt chart, the authors analyzed the differences of the performed procedures applied in the airport. The result of applied research is the identification of the next critical points in the simulation that may potentially represent critical activities of the winter maintenance procedure and have an influence on their optimization.

Sage Math is a complex system that can be applied to perform complicated calculations but can be also used in education. This contribution describes how and in what areas the system can be used in general. In addition, we describe our experiences with this system in the following areas: · Subject teaching - in local network · Elaboration of diploma thesis - in local computer · Research and publishing - in Cloud · Simple calculations in Sage Math Cell server.

Risk management and safety are often-mentioned topics that dominate, especially in this period. The Safety Management System (SMS) is based on risk management, the implementation of which is required in air transport as well as in other modes of transportation. The fact is that the safety of passengers and staff is a priority for every airline, and such individuals are exposed to some common groups of risks. Risk identification is vital in successful risk management as only identified risks can be managed. Based on a study of published frameworks and standards, a risk identification methodology was designed using a prompt list of a logically arranged list of risks concerning typical aviation activities and the specific environment in which the methodology operates. The prompt list was compiled based on a context analysis, which focused on internal and external contexts and on which the structure of the prompt list was based so that risks could be moved from the list to a risk register for further processing based on various criteria. The list contains risks from several areas (economic, ecologic, social, individual, business, marketing, etc.). The design of the prompt list itself also includes a proposal for a methodology for its compilation, use, and updating.
