The article's main purpose is to describe the proposed Methodology, which aims to present an approach to expressing the value of the air transport industry in the Czech Republic. This approach methodically divides the primary and secondary effects and finds metrics based on which the value of the air transport can be quantified. The proposed approach is based on equivalent methodological materials by ICAO, FAA, and other organizations describing and analyzing the value of air transports. The calculations are based on open data sources as well as data that are available by request. The methodology also proposes collecting new data to complete the picture of the value of air transport.

The initial motivation for studying and researching air transport socio-economic impacts is quantifying the value that air transport brings to the Czech Republic. The main challenge is to explore a methodology that would describe the macroeconomic and microeconomic relations within the Air transport industry. These relations will define the directions of the market forces flow and thus the Czech Republic’s value. The authors of the paper use an approach that follows methods and standards for collecting and processing economic and statistical data introduced by the International Civil Aviation Organization (ICAO), Eurostat, and the Czech Statistical Office (CZSO). The authors incorporate economic definitions and standards published by the United Nations under the World Trade Organization (UNWTO) and other accounting and statistical entities, which results in creating a methodical description of chosen relations. The methodical description leads to the quantification of the value. In a practical sense, it is a matter of determining the origin of the data sets according to which the selected relations will be defined. The paper focuses on the expression of Air transport’s primary and secondary effects and the description of the proposals, which will be part of the methodology.

Modern approaches to physical therapy often use electric currents induced by time-varying magnetic fields. Although some of these methods are already commonly used, and only a few studies are looking at applying particular techniques on exposed tissue. In this study, a high-induction magnetic stimulation (HIMS) was applied to the chest area to affect the electrical conduction system of the heart. The animal model Sus scrofa domesticus was used for the study. Standard methods were used to make the subsequent analysis, i.e., heart rate variability in time and frequency domain. Concerning the nonlinear character of the electrocardiographic signal and evaluating complex variability (complexity), recurrent quantification analysis was used. The results show high resistance to a physiologically working heart, but there are also specific changes concerning complex variability. Thus, the results indicate that the HIMS application in the chest area may not pose a significant risk to healthy individuals in terms of the short-term effect of this technique on cardiac activity. However, cardiac activity is still, to some extent, affected by the HIMS application. In view of this and the fact that the study was conducted on an animal model, further research in this area would be appropriate.

Presented article focuses on support and creating of supporting indicators for Evidence-Based Training, Specific orientation lays on assessment of pilot’s performance and heart rate assessment that may indicate psychophysiological condition of pilot. Method of experimental measurements included two groups (Gr. A and Gr. B) of ten subjects that completed simulator training and flight training on real airplane. Influencing factor for transition from analogue to glass cockpit layout was implemented for both groups where one group completed preparation for the transition (Gr. B) and the other did not (Gr. A). Results demonstrate that precision of piloting technique during final phase of training raised within Gr. B compare to Gr. A, however, rANOVA tests revealed that mean heart rate was almost same for both groups across the training phases. In addition to these facts, significant correlation was detected between subjective and exact assessment of pilot precision which together with other presented results represents the fact that pilot performance assessment could be done mainly by monitoring of pilot precision and correctness of performed lessons and manoeuvres. Presented research brings another possibilities for development of pilot training as well as to data-driven training.

Since the beginning, aviation has been exposed to the risk of threats of unlawful acts, such as attacks, hijacks, or bomb attacks. The priority of current safety systems is to eliminate the risk of possible unlawful acts to critical infrastructure. However, tightening the net of security checks has a downside - individuals or organizations execute the act of violence even before the baggage security check done by mainstream spectroscopic methods. Thus, airport terminals with large crowd concentration are becoming a perfect target for terrorists to attack. A factor contributing to forming a crowd is a thorough, time-consuming security check. In a short time, the crowd concentration rapidly increases in an unsecured perimeter and as such, is an easy target. Man-made explosives, as well as several military, industry or difficult to access, have a common component - ammonia. Bombs could be made by various forms of ammonia, like ammonium nitrate, chloraminȩ or a compound of ammonia and aluminum oxide. For that reason, the detection of ammonia present in airports becomes a frequently discussed topic among aviation security experts. The paper aims to create a concept of the sensory network able to monitor in 2D or localize a source of ammonia trace elements. The proposed idea is intended to use in airports, but the concept is also applicable in places where a noninvasive and contact-less passenger or baggage security check is needed.

Modern physical therapy could be conducted in many ways. Some of them are based on methods using the biophysical stimulation with a time-varying magnetic field. Although there are many devices functioning on this principle, the effect of the magnetic field remains arguable. Nowadays, the trend is to use low-frequency electromagnetic fields which allow an induced electric current to form in the exposed tissue. However, the use of such magnetic fields is associated with certain risks. It is questionable whether the application of such magnetic fields in certain locations might affect physiological electrical activity concerning the fact that the electrical current is generated in the tissue. For this reason, this paper aimed to monitor the effect of high-induction magnetic stimulation in an area where the electrical conduction system of the heart could be affected. Although no pathological signs in the ECG record were observed by the supervising physician, the results show that after the application of high-induction magnetic stimulation, the variability of the heart rhythm is affected since statistically significant differences were observed in the values of parameters describing the variability, i.e. SDNN (p = 0.040) and stdHR (p = 0.004), pre and post the HIMS application.

Advisory procedures are meant to be simple operation procedures based on the use of GNSS when flying under VFR, without degrading flight safety. To prove that procedural steps or predetermined manoeuvres are beneficial for pilots, it´s done underwent a series of testing. It was used observation of physiology parameters to obtain quantitative values of the level of psychical condition on testing subjects during VFR flight on simulator with and without GNSS in use, to determine if proper usage of GNSS decreases workload of pilots. The study was attended by 9 students of the Department of Air Transport, CTU in Prague, Faculty of Transportation Sciences. The measured data was collected in the form of bio signals using the VLV-LAB system. For the purposes of evaluating the psychophysiological status of the pilots, a heart rate record was chosen as the main indicator – heart rate variability (HRV), i.e. duration of each R-R interval. Measured data was evaluated by standard methods in the time domain. All measured subjects had a decrease (meanHR), respectively increase (meanRR) of given parameters in with-GPS measurements compared to without-GPS measurements.

Ever-changing situation in the aviation demands a change in flight training programs that would reflect present needs and threats in contrary to the traditional training that didn’t changed much for decades. Therefore, new alternative training concepts have been developed that cover these needs. However, these concepts do not apply to initial training which seem to be a crucial phase of a pilot training. Thus, the aim was to create a software solution that would identify individual flight maneuvers and evaluate them so that the overall evaluation would be done by considering objective evaluation and flight instructors’ subjective expertise. A study was done with strictly given flight schedules. For the purpose of automatic maneuver detection, density-based spatial clustering of applications with noise – DBSCAN clustering algorithm was used, which could determine maneuvers and thus exclude the noise from clusters of maneuvers. The results indicate that the proposed solution was able to identify the prescribed maneuvers with high sensitivity. The solution could be extended in the future to identify all flight maneuvers considering as many parameters from flight data recorder as possible and thus carry out complete objectively based pilot performance evaluation.

Due to increasing safety standards in air transport, the emphasis is put on human factors in this domain. This regards especially the improvement of piloting precision during flight training and the elimination of internal and external influences with negative effect on pilots. This paper is focused on evaluation of pilot’s psychophysiological state during flight training on a simulator and in an aircraft and also on pilot’s reaction on transfer from analogue to digital visual presentation of avionic data. The best indicator for evaluating human’s psychophysiological condition could be a heart rate because of its descriptive activity of human heart and its psychophysiological character based on sympathovagal balance of autonomic nervous system. In this paper heart rate frequency is measured by FlexiGuard biotelemetry mobile device and by a Garmin c chest belt. This paper is oriented towards description and comparison of the most common methods for physiological parameters assessment, i.e. time and frequency domain analysis and non-parametric methods analysis. The paper also describes a wavelet transform. The results show that not every parameter resulting from each analysis could be a good indicator describing pilot’s stress. Results also show which parameters might work as good indicators of pilot’s stress – those are LF/HF ratio and parameters measured by wavelet transform. Best way to define pilot’s stress on simulators in real time indicates to be wavelet.

One of the priority tasks of contemporary security systems is to eliminate risks of unlawful acts related to terrorist attacks on critical infrastructure. Airports, among other things, are part of this infrastructure. Pre-screening of passenger’s baggage chemical composition during entrance into an airport hall, with no need for slowing down of passenger flow or raising suspicion in potential perpetrator of unlawful act during the check process, could eliminate number of casualties of such attacks. Traces of ammonia present in almost every type of explosives provide one of the possibilities to separate suspicious baggage and persons from the rest of passengers. The goal of this work is thus creation of a sensory network concept capable of 2D monitoring or localization of the ammonia traces source in space. Such system could find its application also in rail or bus transportation.

There are many demands placed on centralized security checkpoints of passenger and cabin luggage. Among the most important rank requirements for high passenger satisfaction, assurance of high security check effectiveness and operational efficiency. These three base requirements, however, do not support each other and in some ways they even conflict. Other aspects influencing operational security control are ever increasing volumes of handled passengers and the efforts to reduce flight ticket prices. Operational efficiency evaluation and targeted control are supported by the possibility to assure specific basic requirements. These include assuring required amount of security control staff, on the right place and at the right time. In sequence, a concept of security control efficiency evaluation is needed for operational, tactical and strategic planning.
