Full textIn the second part, the role of law into the airlines' management regime is examined especially in the light of two prima facie conflicting trends: liberalization of market access and increased State involvement in war risk, safety and security issues. Furthermore, the contractual and tortious/delictual exposures of airlines are being scrutinized and the ways to handle them are being analyzed.
The main objectives are (i) to demonstrate that risk management is not restricted to insurance, but involves a number of techniques and procedures that have the potential not only to minimize risk but also to turn risk into opportunity and value and (ii) to identify the role of law as a management tool in the oncoming liberalized aviation environment.

This research considers the commercial aircraft design process from the perspective of program value. Whereas traditionally, the conceptual design of aircraft has often focused on minimum weight, or sometimes minimum cost, this approach demonstrates the feasibility and usefulness of design based on maximum value to the aircraft manufacturer. A program valuation tool is developed and demonstrated that measures the overall program value associated with a set of either one or two new aircraft concepts. The tool is based on a combination of a performance model; a development and manufacturing cost model; a revenue model; and a dynamic programming-based algorithm that accounts for uncertainty in future market conditions and the program's ability to cope with such uncertainty through real-time decision-making. The cost model, using a component-based representation of the aircraft, allows for the consideration of the effects of part commonality on development and production costs. The revenue model, based on an analysis of existing commercial aircraft, estimates a market price and demand forecast for a new aircraft based on several key characteristics. The dynamic programming algorithm, used to find program value, treats annual aircraft quantity demanded as a stochastic process, evolving unpredictably with time. The algorithm borrows from Real Options theory to discount future cash flows using risk-neutral expectations and models the aircraft program as an actively managed project with real-time decision-making to maximize expected program value. Several examples are drawn from the Blended-Wing-Body aircraft concept to demonstrate the operation of the program valuation tool. The results suggest that the value of part commonality between aircraft may be strongly sensitive to the weight penalty and increased fuel burn resulting from a common derivative design. More generally, the example results illustrate the usefulness of the explicit consideration of flexibility in program valuation and the feasibility of a conceptual aircraft design tool based on the metric of program value.

This thesis assesses the performance benefit of electrified propulsion systems for commercial aircraft entering production in a 2035 timeframe. The propulsive power reduction from boundary layer ingestion (BLI), a technology that could be enhanced by electrification, is characterized and bounded by power balance analysis. An aircraft system model extends this analysis to capture the weight and performance trades of electrified architectures, as defined by propulsion system configuration, technology level, and mission. The model quantifies the impact of such architectures on mission energy via optimized aircraft designs. It is found that the propulsive power of a representative narrow-body jet is reduced by 28% with ideal ingestion of the entire boundary layer. Distributed, boundary layer ingesting, turbo-electric aircraft configurations are found to minimize energy consumption for all the missions examined from 500 to 6000 nmi. Energy reductions up to 27% relative to a non-BLI, non-electric, twin-turbofan design are possible. Advanced non-electric aircraft configurations are also examined and found to achieve similar reductions (up to 24%) with fuselage BLI. A parametric characterization of the trade space of electrified configurations illustrates the benefit of a turbo-electric architecture for all the technology levels and missions examined and the limitation of all-electric architecture to mission ranges less than 300 nmi, even with optimistic technology levels.

Full textThis thesis will describe the historic evolution of the economic regulation in civil air transport that laid the foundation for bilateral air transport service agreements and the Open Skies regime. Moreover, the development of bilateral air services agreements, from the Bermuda Agreements to the U.S.'s "Open Skies" Policy, is addressed. Then, a study of the ICAO actions toward liberalization is undertaken.
An analysis from the deregulation, privatization in the American and E.U.'s aviation market to the reform in the Chinese civil aviation is conducted. Under the impact of the global liberalization trend, the Chinese aviation industry is creating a "deepen, widen" reform. Specifically, China Southern's imminent entrance into SkyTeam will significantly push the Chinese aviation policy toward liberalization. A detailed comparative study of bilateral air transport agreements between China, the United States, and Germany will show the recent progress of the Chinese aviation policy.
Finally, an argument for the separation of air cargo from air passengers in the liberalization process, especially for China's negotiation of bilateral agreements, is presented.

In-Space Manufacturing (ISM) promises to revolutionize space systems by reducing mass, lowering costs, and enabling entirely new designs through the orbital fabrication of components in the space environment in which they are intended to operate for their entire life. Because ISM changes many long-standing launch-related design constraints, a new approach for the design and fabrication of space systems must be developed. Technology development planning for ISM is complicated by the existence of various proposed commercial ISM architectures, each with their own technologies, products, and costs. Instead of attempting to estimate these highly uncertain quantities, this analysis informs ISM technology targeting by identifying the key system drivers, maximum allowable lifecycle cost, and minimum required performance for an ISM architecture to be cost-effective relative to the existing launched approach. This analysis is accomplished by first forming generalized classes of ISM applications based on the design constraints relaxed using ISM, such as launch loads, fairing volume, standard gravity, and launch schedule. These generalized classes, which include structurally optimized systems, larger-than-launchable systems, Earth-return systems, and on-demand manufactured systems, are shown to be collectively exhaustive, but not mutually exclusive. For each of these classes, a bottom-up cost model is developed that captures the impact of key system drivers on lifecycle cost. Then, Buckingham Pi theorem is used to identify nondimensional groups of input design variables, such as the ratio of areal density of launched components to that of ISM components, the ratio of ISM facility mass to that of ISM components, the ratio of ISM product sale price to launch cost, or the ratio of launch cost to material cost. The breakeven point between launched and ISM components is identified as a function of these parameters and nondimensional groups, which serve as technology development targets for commercial viability. It is shown that the presented approach can inform technology development efforts by evaluating the commercial viability of historical, current, proposed, and notional ISM concepts across a broad application space. The best ISM applications can be identified as having a high allowable facility cost without requiring a large total ISM product mass. For the structurally optimized class, ISM of solar arrays appears promising because structural mass can be reduced by up to 85% relative to the technology goal for launched solar arrays. However, ISM solar array mass savings are fundamentally limited by solar cell mass, which can total 5 kg/kW. Of the Earth-return concepts considered, ISM of ZBLAN optical fiber appears most promising with an allowable facility cost of $1.35B based on just 125 kg produced over a five year period at its sale price of $11M/kg. The commercial viability of ISM of ZBLAN is relatively insensitive to launch costs. Interestingly, falling launch costs improve the business case of Earth-return ISM concepts, while weakening that of ISM for structural optimization.

Traditional commercial aircraft design attempts to achieve improved performance and reduced operating costs by minimizing maximum takeoff weight, but this approach (does not guarantee the financial viability of the program to the manufacturer. Improved design practices would take into account not only aircraft performance but also financial aspects of the design. The methodology suggested herein investigates multidisciplinary design optimization (MDO) involving performance and finance jointly in aircraft program design, as well as assessment of program business risk. A value-based MDO framework couples a performance model with an improved stochastic program valuation, accounting explicitly for both uncertain demand via market volatility and managerial flexibility by invoking Real Options theory. Stochastic program value is used as the new objective for the design optimization problem. The methodology and framework developed are applied to a design example for the Blended-Wing-Body aircraft concept. Value-based optimization yields a design with a 2.3%-higher program value than that of the conventional minimum-weight solution.
(cont.) Comparing performance- and value-optimized designs, it is shown that the optimizer chooses to trade aerodynamic efficiency for reduced manufacturing costs. The effects of varying the aircraft range and speed on maximum-value solutions demonstrates that incorporating value into the design process permits more fully-informed program decisions that have optimal financial impact. Sensitivity analyses quantify the impact of technical and financial uncertainty on the stochastic value due to individual program parameters, and permit insight into the relative business risk associated with each for value-optimal designs. The results show that long-term cash flows should be emphasized over development costs. Traditional, deterministic net present value is shown to be inappropriate for use as a MDO objective function. Risk is not addressed adequately through the choice of discount rate, leading the objective to drive the optimization to make poor design tradeoffs and typically resulting in trends contrary to those of the improved stochastic valuation. Value-based MDO represents a logical progression and necessary step in the continual evolution of the aircraft design process.

Full textRather than offering definite answers, this thesis identifies some current and emerging issues in the law of air cargo claims, particularly those aspects that the claimant must prove. The work traces the development of the Warsaw System by writers and courts, and attempts to identify trends in the application and interpretation of the new legal framework. The evolution towards independence of the law of carriage of goods by air from other similar regimes, and the existing connections among them, are examined. When appropriate, common law and civil law solutions to some legal issues will be introduced.
Finally, the thesis concludes that conflicting decisions in this field could be avoided by adopting uniform rules to solve conflicts of laws and to interpret international carriage conventions.

This study estimates the impacts of commercial aviation noise at 181 airports around the world. These airports are located in 38 countries plus Taiwan, with 95 of the airports located in the United States. They are part of the 190 Shell 1 airports in the FAA's Model for Assessing Global Exposure to the Noise of Transport Aircraft (MAGENTA), which comprise an estimated 91% of total global aviation noise exposure [FAA 2008]. The model calculates both physical and monetary impacts of aviation noise. The physical metrics are the number of people exposed to 55 dB or more noise, and the number of people highly annoyed. The model uses a noise depreciation index developed from hedonic pricing studies of housing transactions to monetize the effects on property owners in terms of housing value loss and rent changes. Due to data collection difficulties the impacts are only approximately consistent chronologically. Population data are from the years 2000 and 2001 depending on the country, while house prices and rents are 2006 estimates, and noise levels are for the year 2005. Based on there data, we calculated that around the 181 airports more than 14 million people are exposed to at least 55 dB of commercial aviation noise. Of these individuals, approximately 2.3 million are highly annoyed. We found that the noise resulted in a total of $21 billion of housing value depreciation, which is equivalent to about $1.1 billion per year using a 30-year life of the house and a 3% discount rate, and an additional $800 million of lost rent each year. The impacts are spread over all parts of the world. Although most of the airports included in this study are located in the US and Europe, each continent with an airport in the study had airports with greater than $100 million in housing value loss and greater than 200,000 exposed people.
(cont.) Furthermore, North America, Europe, and Asia each had examples of airports with an estimated $80 million in annualized housing value loss ($1 billion total), 400,000 people exposed to 55 dB, and $25 million in yearly lost rent. We also examined potential changes to these impacts in the future for a scenario with no technological or operational advances to reduce noise (with the exception of retirement of older aircraft in the fleet). Based on an assumption of 2-3% annual growth rates in operations at these airports between 2005 and 2035 with no noise-technology improvements, we found that the undiscounted housing value and rent loss could approximately double by 2035 while the population exposed to 55 dB and highly annoyed could increase by about 70%. These results demonstrate the potential gains from further advances in aircraft technology and operations to mitigate community noise.

The objective of this thesis was to evaluate the environmental trade-offs inherent in multi-criteria objectives of an integrated environmental policy. A probabilistic multi-attribute impact pathway analysis (MAIPA) was formulated to assess the environmental damages of US commercial aircraft operations from 1991-2003. The initial contribution of this work was demonstrating the feasibility of, and identifying requirements for, the FAA Aviation-environmental Portfolio Management Tool (APMT), an integrated assessment capability for US regulatory decision-making. Non-aircraft sources have been found to dictate marginal emissions costs. The implication is that aviation emissions reductions influence neither the magnitudes nor trends in per-unit marginal damages. In contrast, noise mitigation is the dominant influence on the value of per-unit marginal damages. Trends in sum damages were found to depend on the growth rates of air transport relative to other source emissions. Growth in air transport emissions outpaced non-aircraft sources from 1991-2003. Because growth in marginal costs is nonlinear over this period, aviation emissions damages grow faster than inventories. Applying methods similar to MAIPA to estimate damages for future scenarios suggests that stemming climate impacts is fast becoming the priority. A reassessment of the environmental benefits derived from mandated phase-outs of noisy aircraft during the 1990's has been carried out. Previous studies estimated a -80% reduction in population exposure. In contrast, the reassessment estimates a ~2% reduction, providing benefits 17-20 times lower than published estimates of abatement costs.
(cont.) The primary environmental benefit of the noise phase-outs was found to be related to reductions in particulate matter inventories. One way to avoid trade-off inefficiencies is to identify options that bundle benefits. This action provides such an example, where the phase-outs led to reductions in both noise and air quality emissions. Other contributions in the thesis include the following: a treatment of air transport particulate matter emissions, environmental fate, and health impacts of particulate matter; identification that the major source of reducible uncertainty in emissions damages stems from the assumed extent of ozone and particulate matter production in the engine exhaust plume; and quantification of the environmental tradeoffs in decisions specifying aircraft performance for the technology in the US commercial fleet from 1991-2003.

Aviation emissions contribute to climate change, and all-electric aircraft offer an opportunity for zero in-flight emissions. Over the past decade, more than 50 all-electric conceptual, experimental, and commercial aircraft have been researched, with a particular focus on light aircraft. These designs are reviewed, along with progress in battery technology. An all-electric aircraft design and optimization program, TASOPTe, has been developed from an existing version for conventionally-powered aircraft, TASOPT. Both programs are largely based on first-principles, enabling the design of aircraft with unusually short design ranges. A series of optimized 180-passenger aircraft based on the Airbus A320neo configuration are designed and evaluated at 200-1600 nmi design ranges with 2-10 propulsors and 400-2000 Wh/kg batteries. The performance of these all-electric aircraft is compared to advanced conventionally-powered aircraft optimized for the same design ranges.
Optimized all-electric aircraft are found to use two or four propulsors, depending on the design range and specific energy assumed. The design range limits for each specific energy are determined, which are restricted by aircraft weight and performance penalties. A factor of four increase in battery pack specific energy from current values of 200 Wh/kg to 800 Wh/kg enables 500 nmi flights. However, a lower design range of 300 nmi provides improved energy and environmental performance. The required grid power generation circumstances for commercial all-electric aircraft to become net environmentally beneficial is determined for each specific energy assumption. The entire energy conversion chain, including charging, transport, and discharging of electrical energy, is considered. Despite the higher total energy use, narrow-body all-electric aircraft have the potential for lower equivalent CO₂ emissions if the electrical grid transitions toward renewable energy.
This is largely enabled by the complete elimination of all high-altitude emissions, which would remove associated non-CO₂ warming.
