Subject area Hospitality and tourism management; strategic management; marketing, transportation system management and human resource management. Study level/applicability Undergraduate in business and management and hospitality and tourism management. Case overview This teaching case outlines the historical background, successes and challenges of the national airline of Jamaica. It shows how a national airline, which is a heritage asset and one that has provided nostalgic and sentimental value to the Jamaican people and its passengers, had to be divested. The airline has been faced with several challenges; the major one being high-operating costs, especially in light of the global economic recession. The case also highlights the various procedures carried out by the Government of Jamaica before and after the divestment arrangement and also by the acquirer, Caribbean Airlines. Expected learning outcomes The student should be able to: first, differentiate among the various strategic management terms and concepts used in the case; second, explain the importance of strategic decisions versus emotional decisions; third, assess the environmental factors that impacted Air Jamaica's operation; fourth, analyse the environmental factors that should have been considered by Caribbean Airlines before making the decision to acquire Air Jamaica; fifth, carry out a comparative analysis of the various corporate-level strategies to identify the best option for the Government of Jamaica; sixth, propose reasons why Caribbean Airlines acquired Air Jamaica.

After the dissolution of the first national airline in 2002, the Guinean government attempted to set up Guinea Airlines, but it was unsuccessful. This study aims to analyze the current state of air transport in Guinea and to conduct a diagnostic analysis for the revival of the national airline. The objective is to explore the causes of the failures of various attempts to revive the national company. The findings show that air transport has a positive spillover externality to economic long-run growth and the revival of Guinea Airlines could be a major asset to boost the country’s economic growth.

Full textAbstract:
As already noted in the previous work, “Nutrition on Aircrafts: a Menu Analysis (Part 1)”, the organization of passenger service for air transport consists not only in the transportation of passengers, but also in the organization of meals on board airliners. The assortment of dishes depends on many factors such as: budget of the airline, season, flight duration, class of service, departure time, national characteristics and category of passengers. In this paper, the menus of Nordwind Airlines and Azur Air are considered. The airline “Nordwind Airlines” at the stage of purchasing tickets offers its passengers the opportunity to form their diet from the proposed list of dishes for an additional fee. Typically, the list includes chicken dishes, meat dishes, pilaf and special nutrition (vegetarian nutrition and nutrition for children), there is also the option “Guaranteed nutrition”, which, depending on the duration of the flight, includes soft drinks; hot nutrition; Tea coffee. “Azur Air” Airlines in the standard package of services provides snacks during the flight or does not provide on-board nutrition at all. Nevertheless, there are several services with which you can receive ready-made culinary products for an additional fee. The airline cooperates with Fly Service LLC (St. Petersburg), which provides various catering services, including on board an airplane. The Restaurant on Board service is available only upon departure from Pulkovo Airport (St. Petersburg). The information on the international rating according to the Skytrax World Airline Awards of the world according to the criterion of “Airline Catering” is presented. Among Russian airlines, only Aeroflot in the Economy Class nomination is present in international ratings. The paper presents a menu with the calculation of nutritional value and calorie content.

Full textAbstract:
The liberalization of the aviation market has enabled low-cost airlines to take over a significant share in the aviation market. Benefits of low-cost models are multiple, both for passengers and for secondary and regional airports, which were neglected in the past and which record significant inflow of passengers with the arrival of low-cost airlines. In the structure of the air traffic in the Republic of Croatia in the last ten years, there has been a progressive growth of foreign low-cost airline operations, which suggests a potential for the operation of a Croatian low-cost airline. This paper defines the criteria applicable to modelling of a low-cost airline in the Republic of Croatia in the relevant context of fleet management, route networking and operator’s processes in traffic technology. It analyzes the dynamics of low-cost airlines operations in the structure of air traffic in Croatia and the impact of traffic on the status of airports and the national operator. KEY WORDS: low-cost airline, traditional airline, airport, route network, fleet management

Full textAbstract:
This study contributes to the area of tourism research by investigating the process by which the air disaster of a national airline affects tourists’ attitude and intention to fly the airline as well as attitude and intention to visit the country. A survey with potential Chinese tourists on visiting Malaysia and flying Malaysia Airlines was conducted. Results show that intention to visit Malaysia is positively affected by attitude toward visiting Malaysia and intention to fly Malaysia Airlines. Attitude toward visiting Malaysia is positively affected by attitude toward flying Malaysia Airlines and negatively by perceived risk of visiting Malaysia. Perceived risk of visiting Malaysia is, in turn, negatively affected by subjective knowledge about Malaysia and attitude toward flying Malaysia Airlines, and positively by perceived risk of flying Malaysia Airlines. Intention to fly Malaysia Airlines, on the other hand, is positively affected by attitude toward flying Malaysia Airlines. Attitude toward flying Malaysia Airlines is negatively affected by perceived risk of flying Malaysia Airlines, which is, in turn, positively affected by usefulness of (negative) public opinion. The theoretical contribution, managerial implications, limitations, and future research direction are also discussed.

Full textAbstract:
The aim of the study is to access the economic implication of absence of National carrier in the Nigeria aviation industry. The airline industry is the key drive of the travel and tourism industry and also a major contributor to many countries’ overall economy through international tourist arrivals and departures. The study estimate the amount of revenue Nigeria is losing to capital flights for not having a viable national carrier over the past ten years that is from 2007 to 2016.The estimated amount of revenue loss was examined on airlines offering direct flights on Nigeria to London route, in which we have two foreign airlines (British airways and Virgin Atlantic airline)and a Nigeria’s private national carrier which is Med-view airline. The class of tickets and services in each class of ticket being offered by the airlines was examined. The study reveals an estimate of total of over $6 Billion revenue were being lost to hands of foreign competitors over the past ten years with British airways generating closely to $4 billion, while Virgin Atlantic generated over $2.3 billion and Med-view generated over $133 million in the past ten years. The study also reveals that the higher the passenger carried the higher the revenue and vice versa. However, establishing a national carrier by the federal government is imminent which will express Nigeria culture and to better serve passengers especially Nigerians. Finally, banks and other governmental financial institutions should make available enough funds with longer payback period and little interest for both existing airlines to upgrade their services and new entrants to be able to purchase necessary equipment’s to make them competitive in the market.

Full textAbstract:
Purpose – The main purpose of this paper is to create a model, which specifies the determinants of the airline business. This sector is chosen, as the airline industry is not only influenced by national characteristics, but also characterized by international standards and internationalization processes. Design/methodology/approach – In this paper, a systematic analysis of the research published over the past decades is carried out. This analysis incorporates the most acknowledged concepts and works in the field of airline management. Findings – The main determinants of the airline business are identified as: national culture, airline alliances, the implementation of the low-fare business model, the influence of the state on business, and the impact of market liberalization. The modern airline industry can be partially seen as an embodiment of the neoliberal ideas of the 1990s. Practical implications – The model may be used by academics and practitioners who work in the area of airline business management. Specifically in the case of a merger between two airlines, the model might serve as a useful tool to analyze potential synergies. Originality/value – Although various research has been conducted on describing the way that airline business is done, little focus has been paid on the factors that actually determine and change it. This paper analyzes the unique industry variables by which the airline industry is driven and determined.

Full textAbstract:
This study was conducted to compare the evolution process of air transport networks (ATNs) under different airline business models, and empirically analyzed the causes of evolution differences combining with airline market behaviors. Three representative Chinese airlines (China Southern Airlines, Spring Airlines, and Lucky Air) that belong to three business models (full-service, low-cost, and regional) were examined. Based on mathematical statistics and complex network theory, from spatial pattern, topological feature and central city, the result showed that the airlines have their own unique evolution characteristics of ATNs driven by different business models. China southern airlines as state-owned full-service network carrier, its ATN is easily affected by national policy. Spring Airlines has more flexible and diverse choice in choosing target markets and the ATN had a transformation from a mono-centric divergence network to a two-centric regional one. Lucky Air as a regional feeder carrier, whether navigable airports or navigable routes increasingly concentrated within the southwest of China. This information is important for government to improve the national ATN by developing targeted airlines.

Globally airline performance has been variable with poor performance undermining the confidence of travelers, investors, Governments and other stakeholders. Airline corporate governance is a key determinant of airline performance. However, the relationships between governance and performance is complicated by the diversity of governance arrangements surrounding airlines. This study utilizes the four level model of Scrimgeour and Duppati (2014) to analyze the strengths and weaknesses of airline governance in the Asia Pacific region. Data from firm performance and firm behavior are analyzed for a 14-year period given governance and business choices occur at all stages of the business cycle and governance decisions have impact over multiple periods. Improving trust in the airline industry requires attention to all four levels of governance in a manner consistent with national and international business contexts

Full textAbstract:
Despite significant growth of the domestic airline industry, Indonesia was hesitant to ratify the ASEAN Open Skies Policy (OSP) until 2016. One of the recent findings exposed the increasing concern over foreign–domestic airline competition with too little attention in exploring airline aspirations and the potential interplay between the airline preferences and the state interest. This study empirically investigates the dynamics of domestic resistance to the implementation of OSP, and to what extent the interplay of Indonesian airlines’ business preferences, ASEAN contexts and state interests have contributed to the OSP ratification postponement. Taking some lessons from the OSP ratification, we argue that the efforts towards advancing ASEAN economic integration through the open skies are contested domestically when business preferences showed mixed reactions. There has been little agreement on how the OSP could benefit the domestic airlines following their own business strategy. In the meantime, state principles indicated certain priorities for domestic interests, while ASEAN contexts allowed a member state to practice a negotiated move. The study was conducted using a qualitative method, with semi-structured interviews involving three Indonesian airlines (state and privately owned, full service and budget airlines), government officials, a civil society element and the Indonesian national air carriers association.

Full textAbstract:
This dissertation is a collection of several models to understand airline and passenger dynamics in the National Airspace System (NAS).
Agent-based modeling is one of the most widely used modeling simulation-analysis approaches to understanding the dynamic behavior of complex systems. The usefulness of agent-based modeling has been demonstrated by simulating the complex interactions between airlines, travelers, and airports of a small-scale transportation system. Three airlines, one low cost and two network airlines are simulated to examine how each airline behaves over time to maximize their profit margins for a given passenger demand and operation cost structure. Passenger mode choice and itinerary choice sub modules are embedded in the framework to characterize traveler agent's response to the evolved airline schedule. An airport delay model was implemented to estimate the average delay at each airport. The estimated delay fed into the mode choice and itinerary choice models to update the travel time related variables.
International passenger demand is a very important component of the air transportation system in the United States. The proportion of international enplanements relative to total enplanements increased from 8% in 1990 to 11% in 2008. Nine linear regression models are developed to forecast the enplanements from the United States to each of nine international regions. The international enplanements from the CONUS to each world region are modeled as a function of GDP and GDP per capita of both the United States and the specific region. A dummy variable is also used to account for the effects of September 11, 2001. The total number of international enplanements is forecast to increase from 74.7 million in 2008 to 184.4 million in 2028. The average annual growth rate is expected to be 4.7%.
The European Union – United States Open Skies Agreement, which became effective March 30, 2008. Mathematical models are developed to forecast the effect of EU-US Open Skies Agreement on commercial airline passenger traffic over the North Atlantic Ocean. Nine econometric models were developed to forecast passenger traffic between the United States and nine selected European countries between 2008 through 2020. 68 new nonstop flights between the United States airports and the European airports are predicted by the model in 2020 using the airport pair passenger demand forecast. London, Heathrow is demonstrated as an example for rerouting the excess air travel passengers from one airport to other airports when the airport operational capacity is exceeded.
The proportion of international enplanements relative to total enplanements within CONUS increased from 8% in 1990 to 11% in 2008. 51% of the sampled international and U.S. territories passengers served by U.S. carriers had at least one domestic coupon in 2007. The number of DOI passengers through airport-pairs in each of the historical years (1990-2007) is estimated based on the adjusted 100% international itineraries including pure international itineraries plus the non-CONUS itineraries. The total number of DOI enplanements is estimated to grow from 37.3 million in 1990 to 79.4 million in 2007. 193 CONUS airports are estimated to have at least 10,000 DOI enplanements in 2007. The number of DOI enplanements is forecast to grow from 79.4 million in 2007 to 206.2 million in 2030 with average growth rate of 4.2% per year.
In recent years, there has been an increasing use of secondary airports both in Europe and the U.S. Regional airports have long been considered as a possible source of relief to reduce airport congestion at the hub airport and to efficiently accommodate future air travel demand. The conditions under which the secondary airports develop in a metropolitan area are examined. Fifteen multi-airport systems including 19 Operational Evolution Plan airports and 25 active secondary airports are identified in the National Airspace System. Diverse trends of traffic distribution among airports in the same metropolitan area are observed. We observed that the number of markets served at the secondary airports is less than that at the primary airport in the same metropolitan area. Most of the secondary airports are currently dominated by the low-cost carriers. The share of seats supplied by the low-cost carriers at the secondary airports has increased during the period 1990-2008. Full service carriers concentrate their service mainly on the primary airport in all the multi-airport systems analyzed. The average seat capacity per aircraft at the secondary airports is higher than that of primary airports in most of the multi-airport systems. The secondary airports mainly serve the domestic O&D passengers.Ph. D.

Full textAbstract:
We develop and evaluate two significant modeling concepts within the context of a large-scale Airspace Planning and Collaborative Decision-Making Model (APCDM) and, thereby, enhance its current functionality in support of both strategic and tactical level flight assessments. The first major concept is a new severe weather-modeling paradigm that can be used to assess existing tactical en route flight plan strategies such as the Flight Management System (FMS) as well as to provide rerouting strategies. The second major concept concerns modeling the mediated bartering of slot exchanges involving airline trade offers for arrival/departure slots at an arrival airport that is affected by the Ground Delay Program (GDP), while simultaneously considering issues related to sector workloads, airspace conflicts, as well as overall equity concerns among the airlines. This research effort is part of an $11.5B, 10-year, Federal Aviation Administration (FAA)-sponsored program to increase the U.S. National Airspace (NAS) capacity by 30 percent by the year 2010.
Our innovative contributions of this research with respect to the severe weather rerouting include (a) the concept of â Probability-Netsâ and the development of discretized representations of various weather phenomena that affect aviation operations; (b) the integration of readily accessible severe weather probabilities from existing weather forecast data provided by the National Weather Service (NWS); (c) the generation of flight plans that circumvent severe weather phenomena with specified probability levels, and (d) a probabilistic delay assessment methodology for evaluating planned flight routes that might encounter potentially disruptive weather along its trajectory. Given a fixed set of reporting stations from the CONUS Model Output Statistics (MOS), we begin by constructing weather-specific probability-nets that are dynamic with respect to time and space. Essential to the construction of the probability-nets are the point-by-point forecast probabilities associated with MOS reporting sites throughout the United States. Connections between the MOS reporting sites form the strands within the probability-nets, and are constructed based upon a user-defined adjacency threshold, which is defined as the maximum allowable great circle distance between any such pair of sites. When a flight plan traverses through a probability-net, we extract probability data corresponding to the points where the flight plan and the probability-net strand(s) intersect. The ability to quickly extract this trajectory-related probability data is critical to our weather-based rerouting concepts and the derived expected delay and related cost computations in support of the decision-making process.
Next, we consider the superimposition of a flight-trajectory-grid network upon the probability-nets. Using the U.S. Navigational Aids (Navaids) as the network nodes, we develop an approach to generate flight plans that can circumvent severe weather phenomena with specified probability levels based on determining restricted, time-dependent shortest paths between the origin and destination airports. By generating alternative flight plans pertaining to specified threshold strand probabilities, we prescribe a methodology for computing appropriate expected weather delays and related disruption factors for inclusion within the APCDM model.
We conclude our severe weather-modeling research by conducting an economic benefit analysis using a k-means clustering mechanism in concert with our delay assessment methodology in order to evaluate delay costs and system disruptions associated with variations in probability-net refinement-based information. As a flight passes through the probability-net(s), we can generate a probability-footprint that acts as a record of the strand intersections and the associated probabilities from origin to destination. A flight planâ s probability-footprint will differ for each level of data refinement, from whence we construct route-dependent scenarios and, subsequently, compute expected weather delay costs for each scenario for comparative purposes.
Our second major contribution is the development of a novel slot-exchange modeling concept within the APCDM model that incorporates various practical issues pertaining to the Ground Delay Program (GDP), a principal feature in the FAAâ s adoption of the Collaborative Decision-Making (CDM) paradigm. The key ideas introduced here include innovative model formulations and several new equity concepts that examine the impact of â at-least, at-mostâ trade offers on the entire mix of resulting flight plans from respective origins to destinations, while focusing on achieving defined measures of â fairnessâ with respect to the selected slot exchanges. The idea is to permit airlines to barter assigned slots at airports affected by the Ground Delay Program to their mutual advantage, with the FAA acting as a mediator, while being cognizant of the overall effect of the resulting mix of flight plans on air traffic control sector workloads, collision risk and safety, and equity considerations.
We start by developing two separate slot-exchange approaches. The first consists of an external approach in which we formulate a model for generating a set of package-deals, where each package-deal represents a potential slot-exchange solution. These package-deals are then embedded within the APCDM model. We further tighten the model representation using maximal clique cover-based cuts that relate to the joint compatibility among the individual package-deals. The second approach significantly improves the overall model efficiency by automatically generating package-deals as required within the APCDM model itself. The model output prescribes a set of equitable flight plans based on admissible trades and exchanges of assigned slots, which are in addition conformant with sector workload capabilities and conflict risk restrictions. The net reduction in passenger-minutes of delay for each airline is the primary metric used to assess and compare model solutions. Appropriate constraints are included in the model to ensure that the generated slot exchanges induce nonnegative values of this realized net reduction for each airline.
In keeping with the spirit of the FAAâ s CDM initiative, we next propose four alternative equity methods that are predicated on different specified performance ratios and related efficiency functions. These four methods respectively address equity with respect to slot-exchange-related measures such as total average delay, net delay savings, proportion of acceptable moves, and suitable value function realizations.
For our computational experiments, we constructed several scenarios using real data obtained from the FAA based on the Enhanced Traffic Management System (ETMS) flight information pertaining to the Miami and Jacksonville Air Route Traffic Control Centers (ARTCC). Through our experimentation, we provide insights into the effect of the different proposed modeling concepts and study the sensitivity with respect to certain key parameters. In particular, we compare the alternative proposed equity formulations by evaluating their corresponding slot-exchange solutions with respect to the net reduction in passenger-minutes of delay for each airline. Additionally, we evaluate and compare the computational-effort performance, under both time limits and optimality thresholds, for each equity method in order to assess the efficiency of the model. The four slot-exchange-based equity formulations, in conjunction with the internal slot-exchange mechanisms, demonstrate significant net savings in computational effort ranging from 25% to 86% over the original APCDM model equity formulation.
The model has been implemented using Microsoft Visual C++ and evaluated using a C++ interface with CPLEX 9.0. The overall results indicate that the proposed modeling concepts offer viable tools that can be used by the FAA in a timely fashion for both tactical purposes, as well as for exploring various strategic issues such as air traffic control policy evaluations; dynamic airspace resectorization strategies as a function of severe weather probabilities; and flight plan generation in response to various disruption scenarios.Ph.

Resumo: Este texto apresenta algumas reflexões sobre o uso de pequenas aeronaves na integração e modernização do território brasileiro. O sistema de transporte aéreo, num país de grande extensão territorial, cumpre papel de destaque no estreitamento dos laços regionais e é um elemento de destaque do circuito espacial produtivo da moderna agricultura desenvolvida no Centro-Oeste brasileiro. Agilizando o transporte dos indivíduos e promovendo os contatos face-.a-face, as pequenas aeronaves de rotas não-regulares, em função de sua flexibilidade de deslocamento e de tempo, atuam como vetores fundamentais da integração produtiva do território brasileiro, uma vez que a produção propriamente dita e comando corporativo se dissociaram dadas as possibilidades técnicas do atual período técnico-cientifico e informacional

Full textAbstract:
L’objectif de cette thèse est d’analyser les contributions de Clément Colson à la science économique dans le but de mieux connaître sa pensée, de mieux connaître l’École libérale française au début du XXème siècle, d’étudier l’influence qu’a pu avoir cet auteur sur ses principaux élèves, Divisia, Roy et Rueff, et d’évaluer l’actualité de certaines de ses recommandations.Le premier chapitre montre quels sont les apports théoriques de Colson à la science économique.Pour ses élèves, son principal apport serait la théorie de la détermination conjointe du salaire et du taux d’intérêt. Nous montrerons que cette théorie est proche de la règle de gestion optimale en microéconomie attribuée à Clark ; nous verrons alors que l’on peut parler de découverte multiple.Colson est également intéressant au point de vue de la méthode utilisée. Nous verrons alors qu’il utilise les statistiques et les mathématiques dans ses développements : il est à l’origine d’une évaluation pionnière du revenu de la France, son enseignement impulse le calcul économique, il peut être considéré comme un précurseur de l’économétrie en France. Le deuxième chapitre montre que Colson développe la méthode de tarification des voies de communication exploitées en monopole de Jules Dupuit en proposant des moyens pratiques de révélation des préférences. Nous verrons également que cette théorie est reprise de nos jours avec le Yield Management et par les compagnies aériennes à bas coûts. Le troisième chapitre a pour but de voir comment Colson prend en compte la question sociale. Nous verrons qu’il défend une intervention de l’État plus importante que d’autres économistes libéraux afin d’éviter que les ouvriers ne se tournent vers le socialisme. Le quatrième chapitre étudie l’intervention de l’État préconisée par Colson dans le domaine des chemins de fer. Nous verrons que dans ce domaine où l’État est très présent, l’auteur souhaite le limiter. Il préfère ainsi la concession à la régie et souhaite la construction de nouvelles lignes uniquement si elles sont rentables. Nous verrons qu’à nouveau, la crainte du socialisme n’est pas étrangère à ses positions. Sur chacun des thèmes, nous verrons que Colson accorde à la pratique une place importante. Au niveau théorique tout part de l’observation et se termine par l’observation, au niveau pratique il est marqué par les préoccupations de son époqueThe object of this dissertation is to analyse the contributions of Clément Colson to the economics in order to be better acquainted with his thought, with the French Liberal School at the beginning of the 20th century, to see the influence he had on his main students, Divisia, Roy and Rueff, and to evaluate the actuality of his recomandations. The first chapter develops the Colson’s theoretical contributions.For his students, his main contribution would be the theory of the joint setting of wage and of the interest rate. We will explain this theory is close to the optimal management rule in microeconomics attributed to Clark; we will see we can speak then about multiple discovery.Colson is interesting too from the point of view of the method used. We will see he uses statistics and mathematics in his developments: he makes one of the first assesments of the French income, his lectures develop economics calculus, he can be seen as a precursor of econometrics in France. The second chapter shows that Colson develops the Jules Dupuit pricing method for means of communications exploited by a monopoly by proposing practical way of preferences revelation. We will show too that this theory is used nowadays with the Yield Management and by airline lowcost companies.The third chapter has for purpose to see how Colson takes into account the social question. We will see he argues for a more important State intervention than other liberal economists in order to avoid workers to turn to socialism. The fourth chapter is devoted to the State intervention recommended by Colson in the field of railways. We will see that in this field in which the State is very present, the author wishes to limit it. So he prefers the concession to the public exploitation and wishes construction of new railway lines just if they are profitable. We will see again that the fear of socialism is not stranger to his positions. On each theme, we will see that Colson gives an important place to the practice. At the theoretical level all starts and finishes with the observation, at the practice level he is influenced by the preoccupations of his time

Full textAbstract:
Air transport in Africa is a growing sector. However, the growth does not provide a complete perspective of its health. Several important facts play a role in truly understanding where Africa’s air transport has been, is now, and where it might develop. Air transport volumes in Africa are still very low when compared to the rest of the world. The notion of the national flag carrier is still deeply ingrained in the politics of the air transport sector, and though various privatization attempts have been made, many governments are reluctant to completely hand over airlines to the private sector, or completely depend on airlines from outside the country if a national airline is not economically sustainable. Both anecdotally and empirically, the new challenges for African air transport market development are not so much around liberalization, but rather affordability and the rise of airport charges.

Full textAbstract:
The second chapter opens with a discussion of the history of commercial aviation in Britain. It examines the intricate decision-making process that gave rise to Imperial Airways after the First World War. Rather than focus on the decision itself, the chapter undertakes a close reading of the official conference and committee records, illuminating the racism that informed the process to create government-backed airline travel in Britain. The development of commercial air transport services was not a foregone conclusion for the British government. Officials struggled to figure out if nonmilitarized aviation should foster national interests within Europe or imperial bonds across the empire. Attention to the debates and concerns that arose in decision-making spaces such as conferences and committees reveals the extent to which the empire-state aligned airline travel with the cultivation of imperial practices other than colonialism.

Data regarding people and their activities have been collected over the years, which has become more pervasive with widespread usage of the Internet. Collected data usually are stored in data warehouses, and powerful data mining tools are used to turn it into competitive advantage. Besides businesses, government agencies are among the most ambitious data collectors, especially in regard to the increase of safety threats coming from global terrorist organizations. For example, CAPPS (Computer Assisted Passenger Prescreening System) collects flight reservation information as well as commercial information about passengers. This data, in turn, can be utilized by government security agencies. Although CAPPS represents US national data collection efforts, it also has an effect on other countries. The following sign at the KLM ticket desk in Amsterdam International Airport illustrates the international level of data collection efforts: “Please note that KLM Royal Dutch Airlines and other airlines are required by new security laws in the US and several other countries to give security customs and immigration authorities access to passenger data. Accordingly, any information we hold about you and your travel arrangements may be disclosed to the concerning authorities of these countries in your itinerary.” This is a very striking example of how the confidential data belonging to citizens of one country could be handed over to authorities of some other country via newly enforced security laws. In fact, some of the largest airline companies in the US, including American, United, and Northwest, turned over millions of passenger records to the FBI, according to the New York Times (Schwartz & Maynard, 2004).

Full textAbstract:
The use of flight simulators for pilot training and evaluations is common in the modern aeronautical sector. Whether for airplanes or helicopters, the military and airline companies use this feature to keep their crews operational, safety-oriented and resource-saving. This work presents a proposal for adjusting the washout filter parameters that allows the use of Stewart's platform in helicopter simulators. The identification of the filter parameters was carried out based on tests on an available commercial platform, certified by the company Moog, model MB-E-6DOF/24/1800KG, currently used in the SHEFE helicopter simulator of the Brazilian Army. The work dealt with the physiological aspects of the human vestibular system and its dynamics. Subsequently, the methods for choosing the filter model, and configuration parameters are presented. Three series of tests were carried on the commercial platform and in a real helicopter prepared with special flight test instrumentation. The tests were completed, and the motion platform filter adjustments were made to minimize errors between the movement cues perceived by the pilot in the aircraft and the flight simulator. The results of this work will be used as a basis for the development of a national movement platform for another flight simulator in the development phase.

Full textAbstract:
With research and technology (R&T) development activities for the next generation SuperSonic Transport (SST) being pursued globally over the past few years, the options to proposed airframe and engine concepts appears to be converging. The United States, the Europeans, and the Japanese are all engaged in developing the technologies needed for a future SST that is environmentally compatible and economically practical. Boeing and McDonnell Douglas are part of the team under an R&T contract with the National Aeronautics and Space Administration to develop critical components and enabling materials that will allow industry to make a production decision by 2003. Europe’s three main aircraft manufacturer’s — i.e., Aerospatiale, British Aero-space, and Deutsche Aerospace — comprise the European Supersonic Research Program (ESRP). A primary Japanese effort called the Hypersonic Transport Propulsion System Research (HYPR) project consists of a consortium of four international engine manufacturers and the National Japanese Laboratory. The manufacturers are: Ishikawajima-Harima Heavy Industries Co. Ltd., the Kawasaki Heavy Industries Co. Ltd., Mitsubishi Heavy Industries Co. Ltd., and General Electric Aircraft Engines Company, USA. A recent study by the Japan Aircraft Development Corporation (Reference 1) also addressed the technology requirements for the next generation SST. There are basically three major challenges that must be met before a new SST can become a reality. They are the technical, environmental, and economic challenges. The technical challenges of the propulsion system primarily reduce the development of new materials capable of sustaining higher temperatures and vibration (high and low frequency) over longer exposure times as well as capable of being produced at reasonable costs. Low emission combustors and low exhaust jet noise are the primary environmental challenges, which are a technical challenge in themselves. The economic challenge is to produce an aircraft and propulsion system that allows the manufacturers to recover development and manufacturing costs as well as realize a reasonable Return-On-Investment (ROI). In addition, Life Cycle Costs (LCC) must not be substantially above future subsonic airliners in order to justify premium fares the public would be willing to pay for the time savings of long-distance flights and still be profitable to the airlines.

Full textAbstract:
The potential for UAVs to benefit the civilian consumer is driving the demand for the integration of these vehicles into the national airspace. With UAV accidents occurring at a significantly higher rate than commercial airlines, the urgent issue becomes designing systems and protocols that can prevent UAV accidents, better train UAV operators and augment pilot performance. This paper presents three directions of research stemming from the goal of a UAV piloting and training system. Research direction one is the development of a research platform to assess UAV pilot skills and recreate the sensation of shared fate for UAV pilots. The second research direction looks at utilizing flight simulation packages to create virtual tools for training UAV pilots. The third direction covers the investigation of UAV’s in near earth environments as future applications will place UAVs in these areas.

Full textAbstract:
Aircraft sizing, route network design, demand estimation and allocation of aircraft to routes are different facets of the air transportation optimization problem that can be viewed as individual “systems,” since they can be conducted independently. In fact, there is a large body of literature that investigates each of these as a stand-alone problem. In this regard, the air transportation design optimization problem can be viewed as an optimal system-of-systems (SoS) design problem. The resulting mixed variable programming problem cannot be solved all-in-one (AiO) because its size and complexity grow exponentially with increasing number of network nodes. In this work, we use a nested multidisciplinary formulation and the Mesh Adaptive Direct Search (MADS) optimization algorithm to solve the optimal SoS design problem. The expansion of a regional Canadian airline’s network to enable national operations is considered as an example.

Full textAbstract:
The events of September 11th focused renewed attention on protection of our nation’s critical infrastructure. Utilities across the nation have an increased awareness of risks and are recognizing the potential vulnerability of their physical assets, and also the assets embodied in their employees, their knowledge base, their information technology and their customers. Utilities must now grapple with the possibility that their infrastructure assets may be targets of direct physical threats — or serve as conduits for indirect physical threats. As the concern for protecting our nation’s infrastructure intensifies, each utility is being asked to reassess its ability to provide safe and reliable services to customers and communities as a whole. However, improvements to protection of utility assets must be performed with constraints of limited capital and operating budgets. Security threats from terrorist and related events are relatively new to the utility industry, so standard industry-wide protocols are just now being developed. Serious security practices have evolved in some discrete areas, such as high-risk government buildings, nuclear power plants, and airline terminals. Utility infrastructure physical assets are typically dispersed, so, standard approaches to security (developed for enterprises with highly centralized assets, such as nuclear weapons production facilities) are difficult to apply. Managers must then face a balancing act between demands for security and the resources needed to enact and finance those actions. This paper describes the Vulnerability Self Assessment (VSAT™) methodology and software that provides a structured, cost-effective approach for utilities to assess their vulnerabilities and to establish a risk-based methodology for making necessary changes. The VSAT™ methodology groups utility assets into the classes of People (utility staff), Physical Plant, Knowledge Base, Information Technology Platform, and Customers. The methodology and software are flexible, customizable, and user friendly. VSAT™ software is equally applicable to deliberately caused or natural disasters. In addition to a library of prototypical assets, included in the software application are threat and countermeasure libraries. As users proceed through self-assessments, VSAT™ automatically documents the analysis process during each step. VSAT™ helps users identify critical asset(s) and potential single points of failure (SPFs). The VSAT™ process culminates in a series of risk-reduction-cost reports that presents findings in clear and concise ways. This is important, because the goal is business continuity and, at the end of the day, VSAT™ provides solutions that enable utilities to mitigate risks of business interruptions at least cost.

In ASME 2005 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. ASMEDC, 2005. http://dx.doi.org/10.1115/detc2005-84436.
Full textAbstract:
The compliance with Head Injury Criteria (HIC) specified in 14 CFR 23.562 [1] and CFR 25.562 [2] poses a significant problem for many segments of the aerospace industry. The airlines and the manufacturers of jet transports have made claims of high costs and significant schedule overruns during the development and certification of 16G seats because of the difficulties encountered in meeting this requirement. The current practice is to conduct Full Scale Sled Tests (FSST) on impact sleds. This approach can be expensive, since a new seat may be needed for each test. Moreover, some consider the HIC sensitive to changes in the test conditions, such as sled pulse, seat belt elongation, etc., resulting in HIC results from FSSTs showing poor repeatability. These difficulties make it desirable to devise a cheaper, faster, and more repeatable alternative to FSSTs. This paper describes an attempt to address these issues by designing a device, the National Institute for Aviation Research (NIAR) HIC Component Tester (NHCT) using various multibody tools. This device was then fabricated and its performance evaluated against FSSTs conducted under similar test conditions for some typical impact events that occur in an aircraft cabins e.g. impact with bulkheads. The factors compared for this evaluation are the head impact angle, head impact velocity, HIC, HIC window, peak head C.G. resultant acceleration, average head C.G. resultant acceleration, and head C.G. resultant acceleration profiles. The results of these evaluations show that the NHCT already produces test results that correlate significantly with FSST results for impact targets such as bulkheads and its target envelope is expected eventually to include objects such as seat backs.

Full textAbstract:
The failure of engines on jet aircrafts during the past few years has prompted the National Transportation Safety Board (NTSB) to issue an “urgent” recommendation to increase inspections of the engines on U.S. aircraft. Such uncontained engine failures are particularly dangerous, because flying engine parts could puncture fuel or hydraulic lines, damage flight surfaces or even penetrate the fuselage and injure passengers. At issue is older engines found on small number of jets, and the safety and economic impact damage and fracture risk can have on aircraft engines. For example, high-pressure turbine blades are commonly removed from commercial aircraft engines that had been commercially flown by airlines. These engines were brought to the maintenance shop for refurbishment or overhaul. The blades were removed and inspected for damage. The damage was cataloged into three modes of failure, which are thermal-mechanical fatigue (TMF), Oxidation/Erosion (O/E), and Other (O). These show the complexity of damage in turbine engines and the different mechanisms associated with cause of damage. Hence, life prediction of turbine engine is crucial part of the management and sustainment plan to aircraft jet engine. Fretting is often the root cause of nucleation of cracks at attachment of structural components at or in the vicinity of the contact surfaces. Previous effort presented a model to predict fretting fatigue in turbine engine, which is one of the primary phenomena that leads to damage or failure of blade-disk attachments. The influence of thermal effect and temperature fluctuation during engine operation on fretting fatigue damage were investigated. Leveraging these existing capabilities, the present effort focuses on modeling another important damage mechanism in turbine engine blades, which is erosion at high temperatures. Thus a reaction-diffusion model is implemented in addition to the thermo-mechanical one. The model provides a mean to investigate erosion initiation and propagation in turbine engine blades.

Full textAbstract:
Ridership on Midwest passenger rail lines has been steadily increasing over the past two decades. Between 2005 and 2014, there has been a growth of more than 65 percent, much higher than the national average (approximately 30 percent for the same years). Nevertheless, a number of lines have discontinued their services or are in danger of discontinuance. For example, Kentucky Cardinal, operating between Chicago, Illinois and Louisville, Kentucky was discontinued in 2003, and the Three Rivers train, operating between Chicago, Illinois and New York, New York was discontinued in 2005. The Hoosier State train running between Indianapolis, Indiana and Chicago, Illinois would have faced the same fate recently, if not for the financial support that the state and communities have been providing since 2013. As of October 1, 2013, the State of Indiana, local communities, and Amtrak reached an agreement to support the Hoosier State line for the following fiscal year (2013–2014), and the agreement has continued ever since. In the meantime, the Indiana Department of Transportation (INDOT) was the first nationally to announce a Request for Proposals to seek competing solutions from independent providers, as allowed by the Passenger Rail Investment and Improvement Act of 2008 (PRIIA), in order to obtain private-sector competitive bids for the operation of the Hoosier State train. Recently, after many unfruitful attempts and many obstacles, INDOT reached an agreement with Iowa Pacific Holdings. The company has been providing the locomotives for the line since August 2015, and collaborates with Amtrak to keep the train in service, with a shared vision to increase service frequency, improve speed and maintain a reliable schedule, and provide better on-board amenities. However, to ensure the financial viability of the system and support any improvement or expansion, an increase in ridership is necessary. To achieve this, it is essential that we understand the opinions of Indiana residents, passengers of the Hoosier State train, and advocates of the line towards passenger rail. This paper presents the results of a survey that was conducted on board the Hoosier State train to solicit information pertaining to the perceived ease of use and usefulness of the passenger rail services, riders’ opinions, and other factors that might affect behavior toward passenger rail transportation, as well as factors that affect an individual’s mode choice in general, such as habitual automobile behavior, or external impedance factors like schedule and route restrictions. The survey was endorsed by INDOT and approved by Amtrak and Iowa Pacific Holdings. In addition, this paper presents how opinions toward passenger rail differ among different groups based on socioeconomic and demographic characteristics, familiarity with passenger rail transportation in general and the Hoosier State train specifically, and usage. Furthermore, in order to prioritize service improvements that can foster an increase in the Hoosier State ridership, this paper explores mode choice decisions through the use of a multi-attribute attitude model. The results of this paper can guide policy and planning decision making that aims to foster an increase in passenger rail ridership through a mode shift from personal automobiles and competing mass transportation systems, such as airlines and intercity buses.
