Aircraft arrival and departure procedures are designed by air navigation service providers to enable the orderly and safe flow of air traffic. However, in actual operations, flights often deviate from standard routes, especially within terminal airspace. In this context, this paper presents an analysis of the determining factors for the lateral deviation (LD) of flight paths compared with the standard aeronautical departure and arrival procedures. For that, aircraft tracking data recorded by surveillance systems were leveraged and a linear regression model was employed to map structural and operational factors into LD. Our results indicate that LD tends to decrease with increased demand and low ceiling or visibility conditions. On the other hand, convective weather tends to increase LDs as additional holdings and rerouting may be necessary. Besides, significant levels of deviation can be associated with some specific arrival and departure procedures.

Members of the Civil Air Navigation Services Organisation have committed themselves to measure and improve safety culture within their organizations by 2013 ( CANSO, 2010 ). This paper attempts to offer support to air navigation service providers that have already implemented a standardized safety culture survey approach, in the process of transforming their safety culture based on existing survey results. First, an overview of the state of the art with respect to safety culture is presented. Then the application of the CANSO safety culture model from theory into practice is demonstrated based on four selected case studies. Finally, a summary of practical examples for driving safety culture change is provided, and critical success factors supporting the safety culture transformation process are discussed.

Aviation is one of the types of transport which has a crucial role in the modern world and develops with unprecedent speed. As the number of flights tends to increase, the Air Traffic Management (ATM) system has to ensure the safety of these flights and effectiveness of them. The design and use of the European routes and use of the air route network are considered to be a major causal factor of flight inefficiencies in the continent. The present ATM system needs to be reorganised to satisfy airspace operator needs and maintain safety levels, because of the recent and future predicted traffic growth and not always satisfactory indicators of the efficiency of the ATM system.The airspace is currently fragmented along national borders that is why the efficiency of flights is not assured i.e. to perform flights along optimal trajectories avoiding delays, excessive fuel burn and emissions. One of the conditions for ATM system to be more effective is connection of the airspace blocks, into Functional Airspace Blocks (FAB), within which more efficient flight could be conducted based on more direct routes connecting entry and exit points of the FAB. According to the analysis on European and US ATM systems, where the European ATM system is the sum total of a large number of separate Air Navigation Service Providers (ANSP) whereas the US system is operated by a single ANSP, it was analysed and stated that the less fragmentation there is, the more efficient flights are.The focus of this paper is to show the differences between fixed routes and direct trajectories (Great Circle) in the Baltic FAB in terms of flight distance, fuel burn and emission.

Santrauka Aviacija – viena iš greitai augančių transporto šakų, kuri yra svarbi šiuolaikiniame moderniajame pasaulyje. Kadangi skrydžių nuolatos daugėja, oro eismo valdymo (OEV) sistema turi užtikrinti skrydžių saugą ir efektyvumą. Europos oro maršrutų išdėstymas ir naudojimas laikomi svarbiausiais skrydžių neefektyvumo veiksniais žemyne. Dėl esamo ir numatomo oro eismo augimo ir ne visados patenkinamų OEV sistemos efektyvumo rodiklių esama OEV sistema turi būti reorganizuota, siekiant užtikrinti oro erdvės naudotojų poreikius ir palaikyti reikalingą saugos lygį.Šiuo metu oro erdvė yra sudalyta pagal kiekvienos šalies valstybines ribas, dėl to skrydžių efektyvumas nėra optimalus, t. y. atliekami skrydžiai nevykdomi pagal optimalias trajektorijas vengiant užlaikymų, mažinant naudojamo kuro sąnaudas ir emisijas. Viena sąlyga, siekiant OEV sistemą padaryti efektyvesnę, – sujungti oro erdvės blokus į funkcinius oro erdvės blokus (FOEB), kur skrydžiai būtų vykdomi tiesesniais maršrutais tarp įskridimo ir išskridimo į FOEB taškų.Atlikus Europos OEV ir JAV sistemų analizę matyti, kad Europos OEV sistema susideda iš daugybės atskirtų oro navigacijos paslaugų teikėjų, o JAV sistemą valdo vienas oro navigacijos paslaugų teikėjas. Konstatuota, kad ten, kur fragmentacija mažesnė, skrydžių efektyvumas didesnis.Straipsnio tikslas – parodyti skirtumus tarp fiksuotųjų ir laisvųjų maršrutų Baltijos funkciniame oro erdvės bloke skrydžių atstumo, sunaudojamo kuro ir emisijų faktoriais.

As air traffic is continously growing and the number of potential hazards for safety is also rising, improvement of management systems is required to ensure an adequate level of safety. The management of change constitutes an important part of the safety management system (SMS) defined in Annex 19 to the Convention on International Civil Aviation. It is one of twelve elements of SMS found in the ‘Safety assurance’ component. The management of change put in place in an aviation organisation demonstrates the considerable development of an SMS. This process is essential for managing safety in an efficient way. The article reports on the state of implementation of the management of change in selected civil aviation organisations and also points out the difficulties related with carrying it out in everyday life. The paper focuses on managing changes of certified aerodromes and air navigation service providers. In the conclusions, tools are proposed that enable the reader to improve the process.

EUROCONTROL aims at improving the design and use of the European routes. Inefficiencies in the design of airspace and use of the air route network are considered to be a major causal factor of flight inefficiencies in Europe. The European ATM system is the sum total of a large number of separate Air Navigation Service Providers (ANSP) whereas the US system is operated by a single ANSP. Airspace fragmentation following National Borders makes flight routes inefficient due to non requested air routes, flight time, excessive fuel burn, CO and NOx emissions. That is the reason why airspace and the fixed route network should be reorganised to satisfy airspace operator needs and maintain required safety levels.The focus of the paper is to show the differences between planned flights and actual trajectories in terms of flight distance, duration and fuel burn. In connection with this, an overview of these indicators in Europe and the USA was made. EUROCONTROL siekia pagerinti Europos maršrutų planus ir jų naudojimą. Neefektyvus oro erdvės planų ir oro maršrutinio tinklo naudojimas laikomas viena pagrindinių Europos skrydžių neefektyvumo priežasčių. Europos oro eismo valdymo (angl. ATM) sistema sudaryta iš daugelio atskirų oro navigacijos paslaugų teikėjų (angl. ANSP), o JAV sistema valdoma vieno oro navigacijos paslaugų teikėjo. Oro erdvės susiskirstymas pagal valstybių ribas daro skrydžio maršrutus neefektyvius dėl nepareikalautų oro maršrutų, skrydžio laiko, per didelio kuro sunaudojimo, CO ir NOx išsiskyrimo. Štai kodėl reikėtų pertvarkyti oro erdvę ir fiksuotų maršrutų tinklą, norint patenkinti oro erdvės operatorių poreikius ir išlaikyti reikalingą saugumo lygį. Šio straipsnio tikslas – parodyti skirtumus tarp suplanuotų skrydžių ir realių trajektorijų, įvertinant skrydžio atstumą, trukmę ir kuro sunaudojimą. Be to, buvo padaryta šių rodiklių apžvalga Europos ir JAV mastu.

This paper deals with the on-going process of commercialisation of air navigation service providers (ANSPs) with specific focus on Europe. First part offers overview of conducted research on their commercialisation and identifies two main external drivers for the emergence of commercialisation – liberalisation of national markets and demand for other ANS related services. Our research also proposes methodology for numerical assessment of the degree of commercialisation based on the ANSP’s Commercialisation Index (ACI) and presents numerical evaluation of the ACI index of 35 European providers and proposes six different categories of providers reflecting different degree of their commercialisation. Results reveal that 63% of the European ANSPs show signs of commercialisation. On top of that, our outcomes prove that corporatisation cannot be considered a direct manifestation of commercialisation. Despite the most widely accepted view that corporatised providers are commercially active, the findings show that almost 40% of corporatised European ANSPs are not commercially active. The paper also claims that ownership of subsidiaries and joint ventures is the most dominant demonstration of commercialisation. At the same time, our outcomes show that the provision and development of commercial services and products related to ANS are the most common commercial activities of the European ANSPs.

Fragmentation has been suspected of contributing to inefficiencies in the European Air Traffic Management (ATM) system. Heterogeneities between providers may contain multiple aspects, such as airspace structure, staff rostering, or systems used for flow management. Applying the scientific approach of data envelopment analysis, this article provides a new outlook on the relationship between airspace fragmentation and efficiency in the admittedly complex and highly dynamic environment of European ATM. We show that there are airspaces that might benefit from economies of scale, but that there is a tipping point where diseconomies of scale occur. Subsequently, the current approach of functional airspace blocks might inhere inefficiencies for some air navigation service providers.

Road network performance (RNP) is a key element for urban sustainability as it has a significant impact on economy, environment, and society. Poor RNP can lead to traffic congestion, which can lead to higher transportation costs, more pollution and health issues regarding the urban population. To evaluate the effects of the RNP, the involved stakeholders need a real-world data base to work with. This paper develops a data collection approach to enable location-based RNP analysis using publicly available traffic information. Therefore, we use reachable range requests implemented by navigation service providers to retrieve travel times, travel speeds, and traffic conditions. To demonstrate the practicability of the proposed methodology, a comparison of four German cities is made, considering the network characteristics with respect to detours, infrastructure, and traffic congestion. The results are combined with cost rates to compare the economical dimension of sustainability of the chosen cities. Our results show that digitization eases the assessment of traffic data and that a combination of several indicators must be considered depending on the relevant sustainability dimension decisions are made from.
