The development of airport security screening systems requires the use of increasingly sophisticated and effective equipment to detect prohibited or hazardous items and substances. However, this can lead to a reduction in the throughput of the security checkpoint (SCP). This paper addresses the operationally important problem of the dilemma between screening effectiveness and screening checkpoint throughput, which is important to the real operational capabilities of an airport. In this paper, a comparison of traditional walk-through metal detectors (WTMD) gates and newer technology body scanners (BSs) was carried out in terms of SCP throughput as an element determining the operational capabilities of the airport. For this purpose, a simulation model was developed to study throughput based on a colored timed Petri net. The analysis showed that, depending on the characteristics of the available staff, the level of terrorist and epidemic threat, as well as the time of year, it is advantageous to use different strategies to vary the size of the stream of passengers directed for screening by the WTMD gate and BS.

Aviation safety training requires meticulous procedures and constant updating. The development of new technologies in aviation makes it possible to visualize difficult situations and transfer them to various types of simulations. It is theorized that, in addition to basic textbooks, a trainee is able to absorb more material in less time thanks to new tools such as virtual reality. The purpose of this article is to compare the level of training in the traditional mode and with the use of a VR lab. The research methods presented in this article are in line with the discipline of security sciences, which arises from the social need to learn about the reality around us. Observations made in a study conducted on a group of students provided answers about the opportunities and threats that VR applications introduced in the training system.

Artykuł zawiera analizę porównawczą statystycznych i niestatystycznych metod estymacji macierz kowariancji zakłóceń w przestrzenno-czasowym adaptacyjnym przetwarzaniu (ang. Space-Time Adaptive Processing STAP) sygnału radarowego dla modelu radaru MIMO (ang. Multiple Input Multiple Output). Zaprezentowano istotę, przebieg algorytmu STAP oraz właściwości najnowszych typów metod estymacji macierzy kowariancji zakłóceń. Autorzy przytoczyli w artykule również swój wkład w rozwój tej technologii.

Jakość obsługi standardowych pasażerów przez poszczególne linie lotnicze jest zróżnicowana, gdyż wynika to z subiektywnego postrzegania oczekiwań. Odnieść to bowiem można przede wszystkim do: sposobu świadczenia obsługi pasażerom, serwisu pokładowego, komunikacji z pasażerem czy szeroko ujmowanego bezpieczeństwa. Ważna jest tu także punktualność lotu oraz relacja ceny biletu do komfortu oferowanej obsługi lotu. W literaturze przedmiotu brak jest sprecyzowania skali pomiaru tej jakości. Materiał przybliża metodologię tego zagadnienia, precyzując stosowne mierniki oraz ich wagi. W sumie pozwala to wypracować określone standardy dla poszczególnych usług oferowanych pasażerom. Taka konkretna wycena może posłużyć do właściwie prowadzonej polityki marketingowej danej linii lotniczej oraz uzyskania przewagi konkurencyjnej między nimi w zglobalizowanym rynku. Analiza poziomu zadowolenia pasażerów ze świadczonych usług pozwala na podjęcie działania, aby podnieść jakość oferowanej obsługi. Stąd cel niniejszego artykułu stanowi wskazanie próbnego opracowania metodyki pomiaru obsługi pasażerów korzystających z linii lotniczych.

The quality of standard passenger service by individual airlines is varies due to a subjective perception of expectations. It is mainly related to: handling label; on-board service; communication with passengers or broadly understood safety and security. The punctuality of the flight and relation between ticket price and service comfort as well as flight are also important here. The subject literature does not specify the scale of measuring this quality. The material introduces the methodology of this issue, specifying the appropriate measures and their weights. All in all, this allows to develop specific standards for individual levels. Such a specific valuation can be used to advertise your airline and demonstrate competition between them in a globalized market. The analysis of the result obtained allows to take action to improve the quality of services and implement them. Hence, the purpose of this article is to indicate the experimental development of the methodology for measuring the service of passengers who use airlines.

The main purpose of this article is to present the decisive contribution that Brigadier General Ion Bungescu had to the development of anti-aircraft artillery in Romania. To achieve this objective we describe in the paper the evolution of the anti-aircraft gun director computer he invented, as well as its modus operandi.The adopted methods include quantitative and qualitative analyses of documents, manuals and albums published during the considered period, and some published by Brigadier General Ion Bungescu.The results of the article are presented in the context of the accelerated development of military aviation between the two world wars. This development put terrible pressure on the development of anti-aircraft artillery that started with land guns adapted for anti-aircraft firing in 1916 and reached anti-aircraft guns controlled by Gun Director Computer in 1945. We can compare the development of military aviation during that time with the development of information technology over the last 30 years, from connecting computers in the network to the use of artificial intelligence.

In every aspect of aviation’s operations, from ground handling, aircraft designing and production, ensuring the continuity of flights, technical service, to air carriers, there is a possibility that cybercrime may occur. Ubiquitous computers, telephones, and internet carry the risk of various types of threats – from simple viruses, to personal data theft, to taking over of an aircraft by cybercriminals. The aim of the paper is to describe the main cyberthreats in the area of civil aviation. The theoretical analysis of the available source materials and empirical usage of security procedures in aviation organizations served as the main research methods that have been utilized in the analysis of the cybersecurity problem. The author’s extensive professional experience in the aviation sector, especially in the field of quality and security, provided the possibility to verify and understand these vital problems for the aviation industry.
