Is increasing aircraft size common practice of airlines at congested airports?

If the overall demand for air transport grows, but additional airport capacity is not available at congested airports, we could assume that airlines will offer flights with more seats in order to cope with the demand. An analysis of frequency and average seat capacity developments at congested, and not yet congested airports, has shown that the hypothesis of bigger aircraft being used in congested situations is valid in most instances, although not at all airports. The objective of this paper is to report on an analysis of the development of average seat capacity at congested airports, in contrast to the situation at not yet congested airports, and to find out the reasons for airlines increasing the number of seats at congested airports, by means of a statistical model using variables including the degree of airport congestion and average flight distance.     

Airports’ role as logistics centers in humanitarian supply chains: A surge capacity management perspective

The purpose of this study is to investigate the key factors of airport logistics surge capacity and the relationships between these elements. The findings show that successful airport surge capacity management is closely related to prioritizing the flights and operational activities; considering the influx of local people to airports and local infrastructure capacity in the planning phase; developing suitable methods to encourage people to take part in surge operations; providing uninterrupted communication in and out of airport. In view of the above-stated findings this study suggests that airports can meet the surge demand through systematic capacity planning of the existing and additional human, supply, system and space elements by considering experienced or anticipated capacity shortages in disaster conditions.     

Questioning airport expansion—A case study of Canberra International Airport

World air traffic is expected to grow substantially in the next decade and beyond. Associated with this are accelerated programs to build new airports and expand existing ones. However, aviation futures are increasingly contested globally on ecological and resource grounds, and in relation to the quality of life of affected local communities, and to growing fears associated with terrorism, wars and civil unrest. This case study addresses the issues arising from the privatisation and expansion of Canberra International Airport in Australia. Aircraft noise is a major concern for community groups, and land use planning also emerged as a key issue in a highly publicised conflict between a land developer and Canberra airport management. An important outcome is the recognition of the need for independent policy institutes—working in conjunction with community groups—to challenge the prevailing hegemony of the business-political nexus.     

Incorporating annoyance in airport environmental policy: noise, societal response and community participation

Airport capacity continues to be one of the air transport issues that creates the most concern. The major environmental constraint for airports is the noise generated by aircraft. Annoyed communities living around airports have become a limiting factor for airport capacity and operability. This paper brings together the existing literature in the fields of airport environmental capacity, non-acoustic factors of noise annoyance, NIMBYism and environmental conflicts. We also analyze the socio-environmental conflict between Barcelona airport and the community of Gavà Mar. This case shows that the lack of trust between parties, the impossibility of predicting noise exposure, the absence of opportunities for civil society to speak and the difficulty of accessing relevant information foster annoyance and mobilization in the communities that live around the airport. In addition, it is shown that, in such a situation, communities’ reactions can evolve to a post-NIMBY stage in which proactive attitudes replace reactive ones.     

Germany’s changing airport infrastructure: the prospects for ‘newcomer’ airports attempting market entry

Despite fluctuations for economic or political reasons, the number of passengers and volume of cargo carried by air is growing quickly, leading to a shortage of airport capacity in some European regions with few slots available at some hubs. This problem has accelerated the trend towards an increase in airport capacity for larger aircraft everywhere, a process which started in the UK and is now continuing throughout Europe, especially in Germany. Apart from development at the hubs, however, many small airports have also been enlarged, former military airbases have been converted to civilian use, and new runways are to be built in areas away from centres of population. These changes have occurred within a short period of time. In Germany, the number of available airports with runways over 1800 m will have doubled in a period of 10–15 years.     

Future airport terminals: New technologies promise capacity gains

The changing dynamics of passenger processes in future airport terminals resulting from pressures from both the demand and supply side are analyzed in this paper. Short and long term (beyond 2020) developments are studied following technology advances and business plans of airlines and airports. Key technologies affecting the central passenger processing functions include identity management and biometrics, Near Field Communications, Big Data analytics and smartphone applications. A simulation model is developed and used to assess the impact of forthcoming changes on the airport's departure hall. Lisbon Portela airport is used as case study. It is shown that passenger process times at the check-in and security checkpoints are significantly reduced, due to the introduction of passenger facilitation processes, under a range of behavioral, technological and policy uncertainties. The most salient implication of these reductions is the quantified capacity gains in the building which question the need for terminal expansion.     

Airport partial and full privatization in a multi-airport region: Focus on pricing and capacity

This paper studies the capacity and pricing choice of two congestible airports in a multi-airport metropolitan region, under transition from a pure public, centralized airport system to partial or full privatization. We develop analytical models to investigate three privatization scenarios: public–private duopoly, private–private duopoly, and private monopoly. We find that, airports follow the same capacity investment rule as prior to privatization when capacity and pricing decisions are made simultaneously. Pricing rule after privatization becomes more complicated, with additional factors having an upward effect on the privatized airport(s) and a downward effect on the remaining public airport.     

Meetings facilities at airports

This paper investigates the extent to which airports act as venues, the importance that airports place on this type of activity, and whether it is certain categories of airport that are involved in this type of activity. Airports have always been a vital element of business travel in providing access to a destination where business can be conducted or where meetings, conferences and events can be held. In this situation it is largely the availability of air services at the airport that will attract passengers rather than the airport itself. However in recent years airports have become more than just facilitators of access and have developed infrastructure and services (’meetings facilities’) that allow them to become meeting venues in their own right.

The difference between hub and non-hub airports – An airside capacity perspective

Airport airside capacity is limited by the runway system capacity or apron capacity, whichever is more constraining. Sometimes, taxiway system can also impose constraint to airside capacity, but in the case of fully developed taxiway systems (involving parallel taxiway, high speed exits, etc.) that is usually not an issue. To determine which airside element is more constraining it is not always as simple as comparing runway system and apron capacities directly one to another. It is important to understand and take into consideration their relationship. Runway-apron relationship depends on demand characteristics e.g. dominant market segments (e.g. scheduled, charter, low-cost, general aviation, cargo), and/or specific traffic patterns (hubbing or point-to-point services, seasonality in demand, etc.).The paper brings up the issue of available airside capacity under different traffic characteristics, faced by hubs vs. non-hub airports, and the necessity to understand runway-apron interdependency in order to properly identify the bottleneck on the airside. Referring to earlier findings related to apron capacity analysis, the paper summarizes various factors that affect apron capacity at non-hub and hub airports and uses them to define the runway-apron relationship, as well as its role in the process of analyzing airside capacity under various demand characteristics.The main finding is that functional relationship between the runway system and aprons is much stronger in the case of hub airports, and should be carefully considered when analyzing airside capacity. Besides runway capacity, few other variables that affect apron capacity at hub airports are discussed. Generic examples are used to support the discussion.
