Abstract: Air transport is the most dynamically developing branch of transport and the number of services provided by civil aviation is increasing from year to year. However, the conditions in the passenger cabin during the flight differ from those on the ground. The aim of this report is to discuss how the changed environment in the cabin affects the visual system, where eye disorders can cause or exacerbate existing ones and in which diseases traveling by air is contraindicated. Air traveling is generally safe for most passengers with eye diseases, but may cause exacerbation of some diseases of the eye and is contraindicated after some vitreoretinal operations and in the case of ischemic changes of the retina and optic nerve.

The Law

Abstract In the review below the author presents a general overview of the selected contemporary legal issues related to the present growth of the aviation industry and the development of aviation technologies. The review is focused on the questions at the intersection of aviation law and personal data protection law. Massive processing of passenger data (Passenger Name Record, PNR) in IT systems is a daily activity for the contemporary aviation industry. Simultaneously, since the mid- 1990s we can observe the rapid growth of personal data protection law as a very new branch of the law. The importance of this new branch of the law for the aviation industry is however still questionable and unclear. This article includes the summary of the author’s own research conducted between 2011 and 2017, in particular his audits in LOT Polish Airlines (June 2011-April 2013) and Lublin Airport (July - September 2013) and the author’s analyses of public information shared by International Civil Aviation Organization (ICAO), International Air Transport Association (IATA), Association of European Airlines (AEA), Civil Aviation Authority (ULC) and (GIODO). The purpose of the author’s research was to determine the applicability of the implementation of technical and organizational measures established by personal data protection law in aviation industry entities.

"Introduction to Risk and Safety of Air Navigation" is an authorized script compiled on the basis of the curriculum of the course "Introduction to Risk and Safety of Air Navigation" which is taught in undergraduate studies at the University of Belgrade - Faculty of Transport and Traffic Engineering. The scripts are primarily intended for students of undergraduate (bachelor) studies at the Department of Air Transport and Traffic at the University of Belgrade - Faculty of Transport and Traffic Engineering. Scripts can be useful to both master's and doctoral students at the University of Belgrade - Faculty of Transport and Traffic Engineering, especially those who have not completed undergraduate studies at the Department of Air Transport and Traffic. They can also be useful to air transport and aeronautical engineers in order to expand and update knowledge in the field of air navigation safety. The material presented in these scripts relates mainly to civil aviation and is largely based on international standards, recommended practices, regulations and documents which deal with issues related to air navigation safety. As these standards, regulations and documents are subject to frequent changes and alterations, users of these scripts are advised to also use the original (updated) documents, which are listed in the references, in order to take into account any changes that have occurred after the release of the scripts.

City Network

Under the background of economic globalization, the air transport industry developed rapidly. It turns out that the city-to-city network has not been able to adapt well to the development of the society, and the hub-and-spoke network came into being. The hub-and-spoke network demonstrates the advantages of reducing the operating costs of airlines to keep a competitive advantage, and by maintaining the interests of airlines in the rapidly developing context. However, during the operation of aircrafts, they consume fuel and spew a great deal of harmful pollutants into the air, which has an adverse impact on the living environment. This paper explores the impact and external costs associated with hub-and-spoke network in air transport from an environmental perspective. With some mathematical models, we construct a hub-and-spoke network and take a quantitative study on the environmental impact of air transport. For calculating pollutant emissions, meteorological conditions were considered to revise the pollutant emission factors of the Engine Emissions Data Base (EEDB) published by International Civil Aviation Organization (ICAO). The environmental external costs measurement model is employed to calculate the externality of toxic gas and greenhouse gas (GHG). In order to make the study more convincing, two alternative networks are computed: hub-and-spoke network and city-to-city network. It is found that the hub-and-spoke network is associated with poorer environmental impact and environmental external costs because of the different network characteristics and the scale of the fleets. Therefore, under the general trend of green aviation, the environmental impact and environmental external costs associated with hub-and-spoke network in air transport provides a certain reference for airlines’ strategic decision-making.

This paper is based mainly on a study carried out in 1976/7 for the UK Department of Industry into the long-term development of air traffic control systems in Europe by a team drawn from the Civil Aviation Authority, the Royal Signals and Radar Establishment and private industry, in which Coopers and Lybrand provided the economic expertise.Until the early 1970s, air traffic control was almost completely neglected by air transport economists. Economists contributed to the planning of airports and airline operations but not to the third facet of the air transport system. However, in 1970–1, in conjunction with a programme of expansion and improvement of the country's airports and airways, the US Department of Transportation launched a major study of the airport and airways system. This was designed to establish an equitable charging policy between the different categories of user but in the event its recommendations in this area have only recently begun to be followed.

AbstractThe autoradiographic distribution of [3H]nicotine binding sites was examined in the superior colliculus in normal rats and cats, and in animals in which one or both eyes were removed. [3H]Nicotine binding sites in normal animals were densely concentrated in the superficial layers of the colliculus corresponding to the zone of termination of optic nerve fibers. Following bilateral enucleation, [3H]nicotine binding in the superficial collicular layers was drastically reduced. Unilateral enucleation markedly reduced [3H]nicotine binding sites in the colliculus contralateral to the removed eye, with little effect on the ipsilateral colliculus. These results provide further evidence that nicotinic acetylcholine receptors have a presynaptic location on optic tract terminals and may therefore modulate retinotectal transmission in both the rat and cat visual system.

Automated Decision Making

It is well over 30 years since the first (then called) Cockpit Resource Management (CRM) training, now called crew resource management was introduced. It is a shibboleth, a sacred cow as it were, despite many issues, concerns, and changes over the years. Some 21 years ago, 1992, an Air Transport Association (ATA)/Federal Aviation Association (FAA)-Sponsored Workshop was convened in an attempt to deal with some specific CRM issues. Yet the issues and needs as articulated in that workshop, and some newer ones, remain. Thus, this chapter is 21 years overdue, leading to the questions: Why now and is it still relevant? As said, some needs, issues, and concerns remain. The relevancy is that both a critique of civil aviation CRM on many levels and a comparison with current USAF, USCG, and USN CRM are presented. The proposed skeletal template for the long-overdue revision of civil aviation CRM, the R-MPM is shown. Next, a new model for an intelligent cockpit automated decision aid/advisory system, Event Response Integrated Decision Advisories (ERICA), is shown. ERICA came about from 2009-2012 work in automated decision-making tools for the cockpit and the realization that the Revised Mission Performance Model (R-MPM) and ERICA were interrelated.
