This paper aims to identify the parameters that influence the cost competitiveness of helicopter services for scheduled passenger transport on a regional area.

The approach used is based on an analysis of demand and on a bi-level model (modal split model – service supply optimization model) optimization. Performance optimization in the supply of helicopter transport services is obtained by a sensitivity analysis on the recognized cost factors.

The identification of the variation margins in the cost factors that might make an helicopter competitive for scheduled passenger services.

The inability to consider the totality of the helicopters today on the market due to lack of available data on their cost structure.

It is represented by the opportunity of the spread of the helicopter through the strengthening of the competitive position in relation to other transport modes for passenger transport services.

It is represented by the ability to provide air transport services less expensive on the routes that connect the mainland with small islands, especially during the months when the sea conditions do not allow the naval connection causing the insulation phenomenon.

Today, there is a lack of papers dealing with the issue of the performance of the helicopters from the point of view of the transport planner, considering what should be the characteristics of the aircraft to ensure performance to consistent designed services.

This study aims to develop a methodology to compare the feasibility of helicopter and seaplane regular transport of passengers towards destinations across a remote regional tourist context, where a lack of road and rail infrastructure make these alternative forms of air transport competitive.

The authors use a modal split model identifying the quota of passengers that potentially could utilize these two types of services, determined on the basis of previous studies on air transport demand. A technical analysis regarding transport supply is performed to identify the predominant features that should characterize helicopter/seaplane performances. An optimization model is applied to identify the routes that could overcome the breakeven point considering each of the two means of transport. The paper also takes into account the importance of each type of service and its influence on flight infrastructure costs.

Helicopter and seaplane services could improve the access for tourists with high values of time. The helicopter transport could capture a market share ranging from 5 to 20 per cent of tourist travel demand (the amphibian seaplane from 1 to 14 per cent). The shuttle services could be profitable especially for those regional origin–destination pairs involving the two major airports and the most UNESCO visited locations such as Agrigento and the Aeolian Archipelago (into the analyzed context of Sicily). The comparison between the two modes of transport shows that the helicopter has best performances and the seaplane has to land/take-off from sea.

The lack of data on the performances of the whole world production of seaplanes and helicopters (such as Russian, Chinese or US old machines) could give a distortion of the result. On the other hand, all mostly used machines in the world at the moment are considered. A survey on the fear of flight and on the choice between the two different forms of air transport could give a more precise result.

From an economic point of view, an operator could choose with more confidence the means of transport to use under different conditions. The activation of passenger services with seaplanes and helicopters can give an impulse to the growth of little operators and to the tourism. So, this study could be a starting point for authorities to plan a regional network of little general aviation airfields and seadromes (located in the great lakes or near the ports) near the major tourist locations. It could make possible to develop a synergic regional commuting traffic involving the seaplane and the helicopter.

Seaplanes and helicopters represent the most important means of transport when poor accessibility conditions and need of ready and fast connections coexist, for example, the commuting between airports and remote regions or downtowns with high tourist or business impact. The activation of passenger services with seaplanes and helicopters can give an impulse to the growth of little operators and to the tourism, consequently to the regional accessibility and economy.

There is a lack of studies involving the comparison between seaplanes and helicopters. This study could represent an important means to analyze the parameters that influence the possibility of activation for this kind of services and to find the factors that influence the feasibility of business with the two different machines. The encouraging performances of the flying boat suggest a future development of an innovative model of medium- and/or high-capacity amphibian seaplane dedicated to passenger transport. It should have take-off/landing performances less dependent on the sea state.

This chapter provides an overview of the century-long economic history of scheduled passenger airlines services in developing countries. Initially there is discussion of what constitutes a developing country and how airlines activities interact with development processes. It is a broad view which compares and contrasts the varying paths civil aviation has taken within different countries and internationally. It offers some insights as to why airlines are where we are today and as to what the future may hold for developing nations.

This study develops a method for categorizing airports based on the amount of cargo each airport handles in relation to its passenger traffic. Such a categorization allows for systematic comparisons of airports largely specializing in cargo with those that have more balanced freight/passenger roles. The results show that cargo-focused hub airports (i.e., major cargo-handling airports that handle little or no passenger traffic) in the continental United States shoulder a growing burden in freight movement. One of the most successful of these, Chicago Rockford International Airport, has risen to become the 15th largest airport with respect to domestic cargo shipments on the US mainland, while Texas's Fort Worth Alliance Airport and Seattle's Boeing Field also rank among the top 50. A considerable amount of volatility, however, has accompanied the evolution of this specialized grouping of airports over the past 20 years. Presently, among the 100 airports on the U.S. mainland handling the most domestic freight, cargo-focused hub airports serve only a secondary role, handling less than 5% of domestic air freight shipments as measured by weight. Most major hubs operated by air-freight integrators, such as those developed by FedEx and UPS at Memphis, TN, and Louisville, KY, respectively, are at mixed-purpose airports that have a greater balance of passenger and freight activity. The findings point to some of the unique challenges facing airports that specialize in the movement of freight.

This chapter reviews the effects of air transport liberalization, and investigates the roles played by airport-airline vertical arrangements in liberalizing markets. Our investigation concludes that liberalization has led to substantial economic and traffic growth. Such positive outcomes are mainly due to increased competition and efficiency gains in the airline industry, and positive externalities to the overall economy. Liberalization allows airlines to optimize their networks, and thus may introduce substantial demand and financial uncertainty to airports. Vertical arrangements between airlines and airports may offer a wide range of benefits to the parties involved, yet such arrangements could also lead to airline entry barriers which reduce the effects of liberalization. Three approaches have been developed to model the effects of liberalization in complex market conditions, which include the analytical, econometric and computational network methods. These approaches should be selectively utilized in policy studies on liberalization.

This chapter provides a survey of alternative methodologies for measuring and comparing productivity and efficiency of airlines, and reviews representative empirical studies. The survey shows the apparent shift from index procedures and traditional OLS estimation of production and cost functions to stochastic frontier methods and Data Envelopment Analysis (DEA) methods over the past three decades. Most of the airline productivity and efficiency studies over the last decade adopt some variant of DEA methods. Researchers in the 1980s and 1990s were mostly interested in the effects of deregulation and liberalization on airline productivity and efficiency as well as the effects of ownership and governance structure. Since the 2000s, however, studies tend to focus on how business models and management strategies affect the performance of airlines. Environmental efficiency now becomes an important area of airline productivity and efficiency studies, focusing on CO₂ emission as a negative or undesirable output. Despite the fact that quality of service is an important aspect of airline business, limited attempts have been made to incorporate quality of service in productivity and efficiency analysis.

Lufthansa is offering six of the A300‐B2s in its eleven‐plane Airbus fleet for sale in 1984 because, starting next Spring, the airline plans to replace this model — and, subsequently, its Boeing 727s with the more modern, higher capacity A310. The A300‐B2 was designed and equipped specifically for short‐haul work. Five longer‐range A300‐B4s will stay in the Lufthansa fleet. Two of them will go into service with Condor next Summer, while the other three will be refitted for a broader range of operations. With their increased maximum take‐off weight and more powerful engine thrust, they will be able to service Middle‐Eastern destinations and their cabin amenities will be upgraded accordingly, with new seating, expanded catering facilities and an audio system.

In this series of articles, I shall be looking at the past, present, and future of civil aviation safety. The remote past record is of interest, if only to show the giant strides which have been taken in securing safety since the inception of air transport in the early 1920's. The most recent past is of more significance as it provides the best technical indication of where we stand today. The future is perhaps the most interesting of all, but of course facts have to give way to speculation.
