Download or read book Estimating Aircraft Depot Maintenance Costs written by Kenneth E. Marks and published by RAND Corporation. This book was released on 1981-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a series of parametric equations for use in estimating the depot maintenance cost of new Air Force aircraft, particularly for the five major maintenance categories: airframe rework, engine overhaul, airframe component repair, engine component and accessory repair, and avionics component repair. The equations are intended to provide cost estimates for Defense Systems Acquisition Review Council Milestone II, at which point some design details of major aircraft subsystems (airframe, engine, avionics) are available. The report presents a single set of equations that are the most representative and applicable to the widest range of estimating situations, but presents alternative equations and supporting data and analyses for use by the interested reader.

This book was released on 1987 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The model developed in this study has two cost estimating relationships (CERs) for estimating depot maintenance costs in its two categories: depot maintenance cost per Promary Authorized Aircraft (PAA); and, depot maintenance cost per flying hour. The data source used for depot maintenance costs is the Weapon Systems Cost Retrieval System (WSCRS) as developed by HQ AFLC. The CERs developed used empty weight of fighter and attack aircraft to predict the cost of depot maintenance per PAA. For depot maintenance cost per flying hour, the variables used were combat radius, thrust-to-weight ratio, and empty weight. The study found that the F-111 was a significant outlier with respect to the data set, but even when included in the data base the F-111 enhanced the values of the statistics for the model and improved the ability of the model to predict. The relationship found for depot maintenance cost per PAA in the CER developed, was not as strong a predictor as was the CER developed for depot maintenance cost per flying hour. This conclusion agrees with previous studies that have tried to determine significant relationships between depot maintenance costs and those costs attributed to the number of PAA. (Theses).

Available in PDF, EPUB and Kindle. Book excerpt: Part of a larger RAND Project Air Force study on capability-based programming, this report introduces a revealed preference methodology to estimate the value to the United States Air Force of expediting F-15 fighter jet programmed depot maintenance (PDM). Such a valuation estimate would be useful in depot-level cost-benefit analysis. The authors rely on the fact that the Air Force has chosen to pay for intermittent PDM on F-15s to assert that F-15s must have enough value after PDM visits to justify PDM costs. Air Force expenditure data suggest that a typical fiscal year 2005 PDM visit cost about $3.2 million. Using the aircraft valuation curves consistent with PDM being worthwhile, the authors find that expediting an F-15's last PDM visit by a month must be worth at least $60,000. However, using a plausible annual aircraft valuation decline rate, they find that expediting an old F-15's last PDM visit by a month would be worth around $75,000, while expediting a new F-15's first PDM visit by a month would be worth more than $180,000. This report also explores various robustness enhancements. Consideration of aging aircraft issues, for instance, tends to increase the estimated value of expedited PDM.

Download or read book An Estimation of USAF Aircraft Operating and Support Cost Relations written by Gregory G. Hildebrandt and published by . This book was released on 1990 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand the availability of data to identify operating and support (O & S) costs, this Note develops aggregative cost estimating relationships to explain O & S costs. A database called VAMOSC is used in conjunction with other information on aircraft characteristics to relate O & S costs per aircraft to flying hours per aircraft, flyaway cost, number of aircraft, and design age. At the total O & S cost level, flyaway cost is an acceptable proxy for aircraft type and the mission design series year of initial operational capability. These cost estimating relationships give impressive explanatory results; whether they have equal predictive power remains to be seen. They may be helpful for assessing Air Force trade-offs between modernization and operating tempo and eventually for understanding the cost of achieving alternative readiness levels.

This book was released on 1978 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although life cycle analysis is widely used as a management tool, considerable uncertainty still exists about its effectiveness with respect to economic tradeoffs, funding decisions, and resource allocations. This report evaluates some of the most widely used life cycle cost models: AFR l73-10 models (BACE and CACE); the Logistics Support Cost model; the Logistics Composite model; the MOD-METRIC model; AFM 26-3 Manpower Standards; Air Force Logistics Command Depot Maintenance Cost Equations; the DAPCA model; and the PRICE model. The models are rated within a framework incorporating a set of cycle cost elements and a set of cost driving factors. Color-coded illustrations summarize the results. The models are shown to have many shortcomings that limit their usefulness for life cycle analyses in which estimates of absolute, incremental cost are required. Specific areas are identified where driving factor/cost element combinations are not adequately addressed.

This book was released on 2009 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systematically examining the empirical relationship between multiple U.S. Air Force systems' expenditures, flying hours, and fleet sizes, this research suggests a more sophisticated way to think about Air Force costs than is currently used. The report discusses prior research on cost-per-flying-hour calculations--i.e., the practice of multiplying projected flying hours by a cost-per-hour factor in certain segments of the budgetary process. This report looks across Air Force mission designs (systems) and estimates general, historical relationships between expenditure levels and flying hours. A fixed-plus-variable cost structure is estimated with expenditures neither increasing nor decreasing in proportion to flying hours. The author concludes with the policy implications of his findings, noting that current Air Force budgeting approaches likely overestimate funding needs when flying hours are increasing and underestimate needs when flying hours are decreasing.

This book was released on 2007-07-30 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the important national defense contribution of large, non-fighter aircraft, rapidly increasing fuel costs and increasing dependence on imported oil have triggered significant interest in increased aircraft engine efficiency by the U.S. Air Force. To help address this need, the Air Force asked the National Research Council (NRC) to examine and assess technical options for improving engine efficiency of all large non-fighter aircraft under Air Force command. This report presents a review of current Air Force fuel consumption patterns; an analysis of previous programs designed to replace aircraft engines; an examination of proposed engine modifications; an assessment of the potential impact of alternative fuels and engine science and technology programs, and an analysis of costs and funding requirements.
