The COVID-19 pandemic has reduced the mobility of urban residents on an international level. Tourist air traffic was suspended as one of many activities. As a result, the aviation industry has suffered losses at various levels. In addition to carriers, airports are also suffering due to the effects of the pandemic. Their income comes mainly from charges for take-offs and landings of airplanes, passenger charges, and commercial and restaurant activity. In this paper, the authors attempt to estimate the level of losses incurred by six Polish airports in relation to passenger charges. Based on the data for the years 2015–2019, the forecasts of passenger flows for the year 2020 were estimated using the seasonality indicator method, the method of one-name period trends, and models of linear trends with seasonality. Research has shown that the total losses of the examined airports for the year 2020 amounted to approximately 290 million EUR, and these are losses resulting only from the lack of fees charged for servicing passengers at the airports.

Set Up

Airports are essential for intercontinental trade and a key to the success of the global aviation industry. The common objective of all stakeholders in the airport chain is to satisfy the passenger while facing a significant number of challenges, including the continued growth of air traffic and its influence on airport capacity, the problem of congestion in peak hours, and all that result from queuing and boarding delays. This situation forces the managers of the airport to set up a better circuit of passengers, both at departure and on arrival. In fact, to achieve a better flow of passenger within the terminal, modeling is the first step towards developing and solving this problem. The present work aims to present the various models and approaches of simulation and optimization applied to the study of passenger flows and highlight their contributions to the good management and operation in a field as complex as that of airport operations.

The Creation

The subject of research is the development of a method for constructing WEB-services based on cartographic models of airports for organizing passenger flows in conditions of quarantine zoning. The object of the research is the process of managing passenger flows at airports. The objective of the work is to improve the organization of passenger traffic at airports under quarantine conditions with the use of WEB-services based on cartographic models of airport buildings. Conclusions. Using the analysis results of the world's airports activities over the past five years, a steady trend has been revealed towards an increase of the number of flights, and, consequently, growth of the passenger traffic at airports. Also forecasts of air traffic development trends in Europe in the next five years are analyzed, which indicate the direction towards the growth of air traffic. An analysis of the quarantine restrictions impact in connection with the spread of COVID-19 was carried out, which showed that, despite a significant decrease in passenger traffic at airports in the world due to quarantine restrictions, there will be a significant increase in passenger traffic after quarantine relief. Based on the above, it was concluded that it is urgent to improve the organization of passenger traffic at airports under quarantine conditions through the use of WEB-services based on cartographic models of airport buildings. At the same time, the feasibility of using GIS technologies at airports analysis was made, as well as a review of modern information technologies that are currently used to organize the operation of airports in conditions of quarantine zoning. A method for constructing routes for organizing passenger flows at airports in conditions of quarantine zoning has been developed. The methodology envisages for the creation of airports passenger traffic maps using the most modern cartographic software products ArcGIS and ArcGIS Online, it contains recommendations for using a billing Wi-Fi network to track the movement of passengers in airport buildings, and, finally, envisages for the creation of WEB services for cartographic models of airports terminals. Developed with the use of proposed methodology, WEB-services for organizing passenger flows at airports in conditions of quarantine zoning, are convenient and ergonomic in terms of usage by workers of airports and airlines. Moreover, passengers can also quickly receive partial information sufficient to organize their movement in the airport terminal in accordance with quarantine restrictions.

An analysis of the performance of Automatic Dependent Surveillance-Broadcast (ADS-B) data received from the Grand Forks, North Dakota International Airport was carried out in this study. The purpose was to understand the vulnerabilities of Universal Access Transceiver (UAT) ADS-B system and recognize the effects on present and future Air Traffic Control (ATC) operation. The Federal Aviation Administration (FAA) mandated all the General Aviation aircraft to be equipped with ADS-B. The aircraft flying within United States and below the transition altitude (18,000 feet) are more likely to install an UAT ADS-B. At present unmanned aircraft systems (UAS) and autonomous air traffic control (ATC) towers are being integrated into the aviation industry and UAT ADS-B is a basic sensor for both class 1 and class 2 Detect and Avoid (DAA) systems. As a fundamental component of future surveillance system, the anomalies and vulnerabilities of ADS-B system need to be identified to enable a fully utilized airspace with enhanced situational awareness. The data received was archived in GDL-90 format, which was parsed into readable data. The anomaly detection of ADS-B messages was based on the FAA ADS-B performance assessment report. The data investigation revealed ADS-B message suffered from different anomalies including drop out; missing payload; data jump; low confident data and altitude discrepancy. Among those studied, the most severe was drop out and 32.49% of messages suffered from this anomaly. Dropout is an incident where ADS-B failed to update within a specified rate. Considering the potential danger being imposed, an in-depth analysis was carried out to characterize message dropout. Three flight parameters were selected to investigate their effect on drop out. Statistical analysis was carried out and Friedman Statistical Test identified that altitude affected drop out more than any other flight parameters.

Traveled Distances

Airline mergers and acquisitions (MAs) are on the rise across the globe and have been a growing trend in the U.S. aviation industry in the last few years. MAs are taking several factors into consideration, such as cost efficiency, competition, and geographic coverage. For airlines, these transactions can eliminate overlapping routes and help reduce competition, leading airlines to achieve higher operating margins. For travelers, MAs often lead to lesser flight frequency, higher airfares or longer travel miles. To explore spatial-temporal variations from airline and passenger perspectives, this paper focuses on 55 major airports in the 50 largest cities between 2000 and 2010. The detailed results of passenger flow patterns suggest that some airports have more spatial imbalance than others in terms of passenger travel distances. Further, the findings indicate that the MAs have different effects on passenger flows and traveled distances, and the effect is complexly related to the airport’s spatial status.

International passenger and cargo transportation plays a crucial role in the world’s economy, and central to the success of this industry and to its continuous growth is ensuring safe, secure, and efficient operations at a national, regional, and international level. In pursuance of this, the aviation industry is becoming increasingly reliant on technology, with the aim of replacing the human user with technology. The introduction of automation, from its rudimentary beginnings, throughout its constant evolution, is now essential in almost every area of international aviation and is one of the core components in ensuring safe and efficient operations. However, its evolution, which has undoubtedly revolutionised the industry, has not always been free from challenges and controversies. This paper will therefore analyse, from both a manned and unmanned perspective, the benefits and challenges that automation has presented and continues to present to international civil aviation.

The eruption of Eyjafjallajökull in April–May 2010 (hereafter E2010) revealed the fragility of air traffic in the case of an ash-producing volcanic eruption. This study examines developments since E2010 of cooperation between science and aviation-sector service providers toward efforts for improved resilience against a new volcanic eruption. The research builds on literature and interviews with representatives from research and regulatory institutes, air traffic managers, aircraft operators, and engine manufacturers across Europe. The article describes how scientific advice was requested to revise the regulatory precautionary approach and reopen airspace during E2010. The paper depicts the increased effort of scientific advancement in the understanding of ash characterization, modeling of the volcanic ash plume, and atmospheric environment. Furthermore, cross-disciplinary workshops and the memorandum of understanding between Icelandic and British institutions are examined to document increased cooperation between scientists and aviation-sector service providers to provide support to decision makers. However, the science needed for improved risk management is complex and depends on the effects of volcanic ash on jet engines. The concentration levels decided on over the course of a few days in 2010 have not been revised, and the aviation industry does not seem to prioritize research into these issues. A dialogue is needed between science, governance, and engine manufacturers, as well as more collective research funding to test jet engines to improve informed decision making, rather than leaving such research only to the manufacturers and internal political agendas.

Work Type

The fatigue of air traffic controllers (ATCOs) on duty seriously threatens air traffic safety and needs to be managed. ATCOs perform several different types of work, with each type of work having different characteristics. Nonetheless, the influence of work type on an ATCO’s fatigue has yet to be demonstrated. Here, we present a field study in which the fatigue of ATCOs working in two types of work was compared based on an optimized data-driven method that was employed to detect the percentage of eyelid closure over the pupil over time (PERCLOS). Sixty-seven ATCOs working within two typical jobs (i.e., from the terminal control unit (TCU) and area control unit (ACU)) were recruited, and their fatigue was detected immediately before and after shift work using PERCLOS. Using a Spearman correlation test analysis, the results showed that the influence of work type on an ATCO’s fatigue had interesting trends. Specifically, the ATCOs at the TCU who handle departures and arrivals, which include converging with and maneuvering around conflicts, retain normal circadian rhythms. Their fatigue was significantly influenced by the various demands from tasks focusing on sequencing and conflict resolution and by the time phase of a normal circadian rhythm. At the ACU, ATCOs manage flights that are mainly on route, causing monotonous monitoring and routine reporting tasks, and the ATCOs generally have frequent night shifts to handle overflights. Their fatigue was significantly influenced by the demand characteristics from tasks, but changes in fatigue rule were not consistent with a normal circadian rhythm, revealing that the ATCOs’ circadian rhythms may have already been slightly disturbed. Furthermore, the interactions between task demand and circadian rhythm with an ATCO’s fatigue were significantly observed in ATCOs working in the TCU but not in those in the ACU. This study provides first evidence that an ATCO’s work type influences his or her fatigue. This discovery may incite stakeholders to consider work type in the management of employee fatigue, not only in the civil aviation industry but also in other transport industries.
