Book excerpt: This dissertation's objective is to assist the Air Force (AF) in making difficult yet necessary choices regarding its aging fleets in order to fulfill national security objectives at lowest cost. Costs related to maintenance are a key component to the AF's decision-making process. In general, AF fleets are aging. This motivates the AF to want accurate maintenance cost forecasts. Forecasts of its current fleets and future replacement fleets are necessary. This dissertation will use commercial airline data to help the AF make these difficult choices.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Air Force is grappling with the challenge of aging fleets and the optimal time to replace them. This monograph examines commercial aviation data to draw inferences about aging aircraft that may be relevant to the Air Force. It focuses on "aging effects"-i.e., how aircraft maintenance costs change as aircraft grow older. Although commercial aircraft clearly differ from military aircraft, the aging-effect estimates might help the Air Force to project changing maintenance costs over time.

Book excerpt: Seminar paper from the year 2014 in the subject Engineering - Aerospace Technology, grade: 1,3, University of Applied Sciences Wildau (Wildau Institute of Technology), course: Aviation Management 2012, language: English, abstract: Indeed, the majority of airlines are faced with the challenge of aging fleets and when it might be optimal to replace older aircraft. Well, any discussion of the wisdom of retaining capital equipment is usually based on economic arguments. In a competitive environment, airlines are continuously obliged to improve their business and equipment to stay profitable. The prediction of future maintenance costs of the own fleet is an integral element of prospective budgeting projections; on the other hand they serve as a vital part within aircraft replacement calculations. For example if the costs of maintaining the existing equipment on a timely basis exceeds the capital, interest, and amortization charges on replacement equipment, the decision to buy a sort of replacement is straightforward. In most cases the substitute equipment even offers an improved productivity as well (Dixon 2006, p. 1). Beside any debate concerning costs and efficiency, flight safety considerations also enter into the discussion especially in the field of aviation. The question to repair or replace is an ongoing decision making process for the maintenance department of every airline operator. Now the key questions to be answered in this context are: Is it possible to describe a standard airplane service life and how does the fleet age of world’s leading airlines look like? How does the process of maintenance develop over an aircraft’s whole life cycle and can necessary costs be estimated? What can be done technically to keep aging effects of aircraft under control and when might be the right time to withdraw an aircraft from service? In order to answer the abundance of questions my term paper is divided into an economic based part including compiled data and statistics and a more technical part. In the beginning, this paper investigates the ordinary economic life of commercial airplanes. Additionally I’m going to inspect exemplary the average fleet age of world’s leading airlines. In the second stage I am going to describe how to estimate maintenance costs of aircraft that grow older. Further I wanted to clarify technical aspects and problems that might occur more frequently with the rising age of an aircraft.

This book was released on 1996-03-29 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.

This book was released on 2001-05-07 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extending the life of an airframe has proven challenging and costly. Extending the life of an avionics system, however, is one of the most critical and difficult aspects of extending total aircraft system lifetimes. Critical components go out of production or become obsolete, and many former suppliers of military-grade components have gone out of business. From 1986 to 1996, for example, the percentage of discontinued military/aerospace electronic devices nearly doubledâ€"from 7.5 percent to 13.5 percent. In addition, legacy avionics systems, which were designed to meet requirements of the past, generally lack the full capability to perform new missions, meet new threats, or perform well in the new information-intensive battlefield environments. As the legacy aircraft fleet ages, avionics systems will become more and more difficult to support and maintain. Whereas the military once provided a large and profitable market for the electronics industry, the military electronics market today constitutes less than 1 percent of the commercial market. As a result, the military must increasingly rely on commercial off-the-shelf (COTS) technologies for its avionics hardware and software. Although COTS items are generally less expensive than comparable items designed especially to meet military specifications, the technology-refresh cycle for COTS is typically 18 months or less, which exacerbates the obsolescence problem for aircraft whose lifetimes are measured in decades. The short refresh cycle is driven mostly by the tremendous advances in computer systems, which comprise an increasing percentage of avionics content. In response to a request by the Assistant Secretary of the Air Force for Acquisition, the National Research Council convened the Committee on Aging Avionics in Military Aircraft, under the auspices of the Air Force Science and Technology Board, to conduct this study. This report summarizes the following: Gather information from DoD, other government agencies, and industrial sources on the status of, and issues surrounding, the aging avionics problem. This should include briefings from and discussions with senior industry executives and military acquisition and support personnel. A part of this activity should include a review of Air Force Materiel Command's study on diminishing manufacturing sources to recommend ways to mitigate avionics obsolescence. Provide recommendations for new approaches and innovative techniques to improve management of aging avionics, with the goal of helping the Air Force to enhance supportability and replacement of aging and obsolescing avionics and minimize associated life cycle costs. Comment on the division of technology responsibility between DoD and industry.

Available in PDF, EPUB and Kindle. Book excerpt: Extension of aircraft beyond their original design service life or operation in expanded or different roles pose challenges in continuing to operate these aircraft economically or safely. Management of the fleet generally entails increased structural inspection and maintenance, repair of inevitable fatigue damage or possible structural replacement. In a large number of cases structural elements become life limiting or require major rework due to fatigue cracks and damage originating at holes. Hole cold expansion to induce residual compressive stresses around the hole, and thereby minimize the stress concentration effect of the hole, is a proven method for retarding cracks at holes. Reworking existing structure using this technology can significantly extend the fatigue and damage tolerance life and ultimately reduce or eliminate the need for costly ongoing structural inspection while ensuring continued airworthiness without compromising performance or weapons systems capability. This paper discusses the hole cold expansion method as well as derivative technology used to repair fatigue cracked or corroded holes using high interference fit cold expanded bushings. Examples of where the technology is used to extend service lives and restore structural integrity on aging military and commercial aircraft will be presented.

Download or read book Illegal Charters and Aviation Law written by Alena Soloveva and published by Taylor & Francis. This book was released on 2022-07-28 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concerns the subject of illegal charters. The risks associated with illegal charters are high, and the consequences are dire and different for all the parties involved. Pilots can lose their hard-earned licenses, aircraft owners might not get paid by the insurance companies, businesses might be prosecuted and fined, customers do not get what they paid for. The worst consequence of an illegal charter is that someone gets hurt or killed. The tragic part in reading about a flight accident is the understanding that an illegal charter could have been avoided. The present book aims to fulfil the industry’s call for greater awareness, education, and transparency. It will systematically and thoroughly investigate the application of law in a practical context of illegal charters. It engages in a comprehensive comparative study across various jurisdictions, such as the USA, Europe, Russia, Asia and the Middle East. This text considers whether the elements evidencing state practice in regulation of illegal charters are peculiar to the region and legal system. It examines how illegal charters can be prevented and undertakes the analysis of risks and consequences of illegal charters. This is an important book that is likely to have a significant impact on existing scholarship regarding international and national aviation law and be of interest of all parties involved in aviation. This includes industry professionals, legal practitioners, academics, policy-makers, and government officials.
