Aircraft noise-abatement and mitigation strategies

This paper compares and contrasts aviation noise policies and noise-abatement measures currently in effect around the world. With local, national, and regional governments attempting to refine and update their policies towards aircraft and airport noise, this detailed review provides a contextual background to complement aviation noise policy research.     

Post pandemic aviation market recovery: Experience and lessons from China

China was the first aviation market in the world hit hard by COVID-19 and has been recovering gradually as the pandemic became largely under control within mainland China. This study reviews the recovery pattern influenced by the Chinese government's aviation policy choices, in the hope that our discussions and findings will help improve aviation policy responses elsewhere. While the domestic market in mainland China has enjoyed a quick recovery to about 80% of the pre-crisis level by July 2020, the recovery of international services has been much slower, due to the bilateral route and flight frequency/capacity control and strict requirements for health check and quarantine. China's domestic aviation market was recovered by about 80% in two months after the pandemic became under good control. Most other countries with a “curve flattening” strategy, instead of full pandemic control, may not expect the fast recovery path China has achieved. A British “travel corridor” approach may be more practical for Western countries to follow, albeit more likely to be subject to serious setbacks and disruptions. The aviation fee reductions and cost support China and many other countries have been using are helpful by reducing airlines' marginal costs, but not sufficient for carriers to return to profitability or sustainable operations. Capital injection and/or credit guarantee may be needed for many airlines to survive. With various, often uncoordinated, regulations imposed in international markets, airlines based in open economies that have small domestic markets will face particularly serious challenges during the recovery process.     

Apportioning aviation CO2 emissions to regional administrations for monitoring and target setting

Delivering reductions in greenhouse gas emissions from the aviation sector requires support and action from all tiers of government. There has been considerable focus on the policies that can be implemented at international and national levels; however, sub-national bodies can also play an important and influential role. In order to identify what this role may be, it is important for sub-national governments to have an understanding of the size of their potential emissions responsibility. At present there is no widely accepted methodology for the apportionment of either international or domestic aviation emissions to sub-national levels. This paper assesses a number of existing consumer- and producer-based CO₂ apportionment regimes that could be used to allocate the emissions from aviation to regional and other sub-national levels. This is followed by the presentation of a new hybrid consumer–producer apportionment regime applicable to aviation. This new approach is designed to provide an emissions baseline for a region that reflects its share of responsibility for the UK’s aviation emissions as both a producer of emissions and consumer of the services provided by aviation.     

US open skies agreements and unlevel playing fields

We examine the relationship between ‘Open Skies’ agreements (OSAs) signed between the USA and various countries or regions and the existence of subsidies and other forms of protection that advantage one nation's airlines over those of co-signatories to an OSA. We argue that under an oligopoly market structure, strategic competition brought about by OSAs creates incentives to subsidize and/or protect domestic airlines. Such incentives are maintained or amplified by political lobbying efforts that bias civil aviation policies towards producer interests over wider measures of economic welfare. We report on financial aid and policies which have advantaged US airlines during the OSA period and which suggest that unlevel playing fields have been made more unlevel during the era of OSAs.     

How did COVID-19 impact air transportation? A first peek through the lens of complex networks

The current outbreak of COVID-19 is an unprecedented event in air transportation. This is probably the first time that global aviation contributed to the planet-wide spread of a pandemic, with casualties in over two hundred countries. As of August 23rd, 2020, the number of infected cases has topped 23 million, reportedly relating to more than 800,000 deaths worldwide. However, there is also a second side of the pandemic: it has led to an unmatched singularity in the global air transportation system. In what could be considered a highly uncoordinated, almost chaotic manner, countries have closed their borders, and people are reluctant/unable to travel due to country-specific lock-down measures. Accordingly, aviation is one of the industries that has been suffering most due to the consequences of the pandemic outbreak, despite probably being one of its largest initial drivers. In this study, we investigate the impact of COVID-19 on global air transportation at different scales, ranging from worldwide airport networks where airports are nodes and links between airports exist when direct flights exist, to international country networks where countries are contracted as nodes, and to domestic airport networks for representative countries/regions. We focus on the spatial-temporal evolutionary dynamics of COVID-19 in air transportation networks. Our study provides a comprehensive empirical analysis on the impact of the COVID-19 pandemic on aviation from a complex system perspective using network science tools.     

Africa’s single aviation market: The progress so far

To promote the development of air transport at the continental level, several policies were introduced, leading to the Yamoussoukro Decision (YD) in late 1999, which had the liberalisation of the intra-African aviation spaces as its main objective. Even though notable progress has been achieved towards more market-oriented aviation policies, at the pan-African level some markets are still restrictive and inconsistent with the YD, particularly with respect to the granting of 5th freedom rights. This paper aims to examine recent developments in the aviation sector in Africa, with a focus on the implementation of the YD. The obstacles to liberalisation are discussed and several measures for facilitating Africa’s move towards multilateral open skies are investigated. These include, among others, a greater collaboration and co-operation among African airlines, as well as between African airlines and foreign ones; redefinition of the role and responsibilities of different institutions which are instrumental in implementing the YD and some further issues such as ownership guidelines.     

Airlines as instruments for nation building and national identity: case study of Malaysia and Singapore

For many countries, the national carrier has played a significant role in nation building and national identity. Historically, airlines have been regarded as important national symbols and they have been used by governments as ‘chosen instruments’ for projecting their countries internationally. This paper examines the varying ways in which airlines have served to promote nation building and national identity in Malaysia and Singapore. A review of the historical geography of civil aviation development in these two countries shows that this role has evolved over the past few decades in response not only to changes taking place in the marketplace but also in the varying ways in which the governments have viewed their carriers as instruments of their social and economic development.     

The evolving landscape of Chinese aviation policies and impact of a deregulating environment on Chinese carriers

This paper examines the recent developments of China’s aviation polices focusing on airline consolidation, the opening up of the domestic aviation market, and the adoption of more liberal international aviation policy. It then goes onto assess the impacts of the above policies on the industry structure, the performance of major airlines, and the competitiveness of Chinese airlines in international markets. The study shows that the industry became more competitive following the opening up of the domestic aviation market. Although major airlines saw an increase in passenger volume and an improvement in load factors, the falling yield and rising costs make them difficult to grow profitably. Moreover, Chinese airlines largely failed to capitalise on building an international network and the majors were weak in international competition. Strategic use of aviation policy to build a strong and profitable airline industry is still a formidable task lying ahead for policymakers.     

Aviation liberalisation: What headwinds do we still face?

This paper, based on a published report by the International Transport Forum at the Organisation for Economic Co-operation and Development (ITF), examines the issues, or ‘headwinds’, preventing aviation from becoming a truly market-based sector. It paints a brief portrait of the history of regulation and deregulation in aviation and the role of competition policy in a liberalised aviation marketplace. It then focuses on the level playing field, which is often used to argue for protectionist policies and ownership restrictions on air carriers. The paper suggests that some of the controls on market access in place today may do more harm to consumers and the broader economy than good.     

Supporting the needs of special assistance (including PRM) passengers: An international survey of disabled air passenger rights legislation

Passengers who require special assistance at airports and on aircraft represent one of the fastest growing demographics for aviation worldwide. At some airports, annual growth in PRM (persons with reduced mobility) traffic is six times greater than the overall rate of passenger growth yet barriers to accessible air travel remain and disabled passengers continue to exhibit a lower propensity to fly than other travellers. In an attempt to aid disabled passengers’ accessibility to air travel, countries have introduced dedicated air passenger rights and consumer protection legislation which seeks to specifically address the needs of disabled travellers. These regulations typically state minimum service standards and levels of service provision that must be provided by air transport operators to enable disabled travellers to access air travel on an equal basis to other passengers. These legal interventions, however, have been developed on a country-by-country basis and this has created a lack of international regulatory alignment. This paper reports on the findings of an international survey of disabled air passenger rights legislation in 47 countries covering 20 aviation markets (the single market in the European Union and 19 other States). It identifies the differences in regulatory frameworks, highlights their implications for consumers and ultimately concludes by recommending the formation of more harmonised global policy making to better support the needs of special assistance passengers and facilitate their greater mobility by air.     

The air transport market in Central and Eastern Europe after a decade of liberalisation – Different paths of growth

This paper describes the changes which are taking place in air transport for the Czech Republic, Estonia, Latvia, Lithuania, Hungary, Poland, Slovenia and Slovakia in the context of liberalisation. It also attempts to identify the common and specific factors that influence these processes in different markets of the region. The indicators for the development of the aviation market were designed using, among other things, statistics describing the infrastructure facilities and the level of activity in the market. Composite indicators and the weights for their individual components were constructed using a Multidimensional Comparative Analysis. The conditions under which changes were taking place in Central and Eastern European Countries were described with the help of selected socio-economic panel data. Finally, One-Way Fixed Effects and Seemingly Unrelated Regressions (SUR) models describing the development of the aviation markets were estimated. The adopted procedure made it possible to identify the most important common and specific factors that exerted the greatest influence on the situation of air transport in CEE Countries. The very initiation of the liberalisation process undoubtedly had a significantly beneficial effect on the development of route networks and aviation activities as broadly understood. However, the pace of change depended not only on the progress of liberalisation itself, but also on the diverse socio-economic conditions in the individual countries. As a result of the analysis, the markets were divided into two separate groups, which in many respects are distinctly different from each other. The results of the estimation models also showed that there are strong unobservable determinants of development which are specific to individual countries.     

The growing influence of low-cost carriers in Northeast Asia and its implications for a regional single aviation market

This paper provides an overview of the development of the low-cost carrier (LCC) sector in China, Japan, and South Korea. It is the first paper that documents LCC contributions to the passenger traffic and cheaper fares in Northeast Asia (NEA)'s intra-markets. We argue that a single aviation market can facilitate the growth of the LCC sector, which in turn will make a significant contribution to the NEA connectivity, mobility, and integration. In addition, with a single aviation market, NEA countries can adopt a proactive, unified approach in negotiating air transport agreements with the major aviation partners to maximize the interests of this region as a whole, which will further provide valuable growth opportunities for the LCCs.     

Airline ownership and control: A corporate governance perspective

Most countries require substantial domestic equity ownership of designated national airlines, yet changes in international capital markets have significantly altered the way control rights associated with equity are exercised. We argue that in a context of aviation deregulation and liberalization, a new generation of aviation financiers has appeared whose incentives and competence for control diminishes the relevance of the nationality provisions contained in most bilateral agreements. The paper describes recent developments in ownership and control and its impact on airline management.     

International standardization compliance in aviation

The commercial aviation industry is global in the sense that passengers travel around the world from destination to destination. It is also global in that the states of the world (countries) regulate the industry domestically and internationally. There is a unique stage where the world comes together to promote aviation, discuss ideas and establish international standards. This stage is the International Civil Aviation Organization (ICAO). The 191 current member states signed treaties acknowledging their commitment to abiding by the standards and practices established by ICAO. No state is 100 percent compliant with international standards, however, and the purpose of this paper was to explore the relationship between the fulfillment of compliance by individual member states and the safety of the commercial aviation industry in terms of fatality rates. Using a Negative Binomial regression, the results suggested that there was a relationship between compliance with international safety standards and fatalities, as well as associations between fatality rates and member states levels of GDP and population. Implications of this research apply to all ICAO member states as the concerns grow over growing air travel and airspace congestion over the next several decades.

Commercialising a national airline—the Aer Lingus case study

National airlines dominated international aviation in Europe for almost 70 years. They also dominated policy and achieved identification of the national airline interest with the national interest in the era of protectionism. The success of Aer Lingus in achieving regulatory capture of policy making in Irish aviation from 1936 to 1986 is examined. In the present era of competition and privatisation this article examines the commercialisation of Aer Lingus, its relative decline in competition with Ryanair after deregulation in 1986, its reinvention as a low-cost carrier in 2001 and its likely privatisation at a time when most countries are discarding the national airline model.     

New regional aviation policy in India: Early indicators and lessons learnt

In this article, we study the new regional aviation policy of India along with data collected on the performance of the scheme since its introduction in 2016. The scheme has multiple objectives. First, it wants to increase footprints of civil aviation to unserved and underserved airports of India. Second, it intends to make flying more affordable. It comes out, the aviation market in the country has expanded due to the addition of new routes under the scheme but data indicates that there is a regional imbalance in the performance of the scheme. Moreover, there are still questions on the long term sustainability of many routes and finding a solution for neglect of some priority regions. We have identified economic and commercial challenges that need to be addressed for the program to achieve its goals. The insights gathered during the study can be generalized and policy makers and managers of remote area air-connectivity schemes of different countries should find them useful.     

Reviewing the DATAS of aviation research data: Diversity,availability, tractability,applicability, and sources

The field of aviation research is entering the era of big data. While data-driven advancements in aviation have clearly brought about applicable models and results with immediate implications, we argue that the influx of aviation data should be better characterized and documented to enable more efficient and standardized usage. To this end, we examine 200 well-cited research articles from sub-disciplines ranging from revenue management to air traffic control published on or after 2010 in order to analyze the diversity, availability, tractability, applicability, and sources (DATAS) of data utilized in aviation research. We find high levels of data diversity within aviation research, with 16 data categories ranging from air traffic flow management-type data to data from distributed sensors in line with the Internet-of-Things (IoT) paradigm. We identified a dominance of proprietary, non-public data in aviation research, with 68% of the 200 research articles utilizing solely proprietary data in deriving their results, and a further 8% utilizing a mixture of proprietary and publicly available data. The pervasiveness of proprietary data has implications on reproducibility and extending research results. We also highlight the increasing tractability of the data by surveying the computational power required to process the data sets, and present vignettes of applications and results that stem from these data-driven studies. Finally, we propose several recommendations regarding standardizing data source nomenclature as well as increasing the availability of and usage of publicly available data.     

Aviation insurance and the implementation of the small aircraft transportation system

Aviation insurance is a unique field from a business, legal, and regulatory standpoint. Issues such as risk management, contracts, and liability raise particular challenges within this highly specialized market. The implementation of the small aircraft transportation system (SATS), as envisioned by NASA and its industry and academic partners entails a thorough analysis of aviation insurance to determine whether the current market structure could support this major policy initiative. In this paper, we investigate the impact of the current legal, regulatory, and market environments on the implementation and development of SATS. The primary goal is to determine what obstacles these conditions would raise vis-à-vis SATS’ implementation. We also seek to identify strategies, alternatives, and regulatory policies that would help achieve a successful transition to a modern, efficient, and fully developed market for small aircraft transportation services.     

Maintaining competitiveness of aviation hub: Empirical evidence of visitors to China via Hong Kong by air transport

Prior studies have not extensively researched and explored the key determinants (aviation and tourism attributes) that could affect Hong Kong’s competitiveness as a transit hub for international visitors using Hong Kong as a stopover to Chinese cities when travelling by air. This study adds to that knowledge to empirically investigate Hong Kong’s eight major tourist source markets (Germany, India, Japan, Singapore, South Korea, Taiwan, the UK, and the US), and also provides an insight to policy-makers in Hong Kong to help them understand the factors that influence Hong Kong’s aviation hub competitiveness and tourism development. The findings of the study suggest that increased air transport capacity from foreign countries and Hong Kong to China, trade volumes between China and its trading partners, air transport costs, and the global financial crisis are the key factors affecting the number of visitors to China by air passing through Hong Kong as their preferred stopover. The policy implications of the findings are discussed.
