Consideration of the problem of predicting avionics develop ment and production cost before a detailed description of the hardware's physical make-up is available. Fire control radars and airborne digital computers were chosen to illustrate the techniques. The approach is to derive cost estimating relationships (CERs) which use technical design parameters of critical interest to the engineer and which incorporate a measure of the projected equipment's advancement in the state of the art. The radar and computer examples show that accurate CERs can indeed be established based on technical parameters. They are, however, subject to rather wide variances, which require care in using them to estimate costs at the low end of the scale.
The case history of a life-cycle cost study performed on the AN/ASN.101 gimbaled electrostatic gyro aircraft navigation system is presented. This study takes into account all the procurement and maintenance costs encountered in the ten year service life of the system. The validity of existing cost standards is criticized, and the need for simple, standardized life-cycle costing procedures is em. phasized. The contributions of other disciplines, among them maintenance and reliability techniques, to reducing the overall cost of ownership are discussed.

Orthophoto project planning. D. Hobbie (Cari Zeiss, Oberkochen, West Germany). Photogrammetric Engineering, vol. 40, Aug. 1974, p. 967.984.
It is the purpose of project planning for the production of orthophotos or photo maps to lay down the parameters to be used for the photoflight and differential rectification. After classification of the known orthoprojection instruments, the parameters of 'focal length', 'photo scale', 'flight data', 'end and side lap' as well as 'design and time of photoflight', guidelines are developed. As regards rectification, various factors affect the parameters of 'scan width' and 'scanning speed".

Basic activities in the conduct of a reliability program are related to technical program aspects, management visibility and control, and philosophical concepts of a reliability program. Questions of initial or preprogram planning are examined. The program manager must make certain that a realistic, achievable goal is defined for the reliability program. A program manager's checklist is presented. Major management functions are summarized, taking into account the evaluation of the actual status of each activity in relation to the schedules, reliability task status reports, and reliability monitoring,
Air travel and economy of materials - Often too much, sometimes too little (Luftfahrt und Materialwirtschaft Oft zuviel-manchmal zuwenig). W. H. Kuhl. Flugrevue/Flugwelt International, Aug. 1974, p. 29-33. In German.
The problems encountered by large airlines in keeping themselves supplied with spare parts are described. Care is needed to ensure fast availability without wasting money on excess inventory. This problem can be alleviated somewhat by intelligent ordering procedures, and by pooling of parts, service, and warehouse facilities among major firms flying to remote airports. Modern data processing can also be effective in estimating various part lifetimes and planning inventories. Further, fast access to available spare parts can be facilitated by elaborate shelving procedures such as the Lufthansa vertical warehousing setup which uses multitiered shelves with special vehicles that move through the stacks.
Avionics cost reduction through improved tests. R. M. Genet (USAF, Aerospace Guidance and Metrology Center, Newark Air Force Station, Ohio). In: NAECON '74; Proceedings of the National Aerospace and Electronics Conference, Dayton, Ohio, May 13.15, 1974,
New York, Institute of Electrical and Electronics Engineers, Inc., 1974, p. 534-538. 32 rets.
Over the past five years, new analytic techniques have been developed and applied to the evaluation of the economic significance of build and test errors in avionics repair processes. The cost of such build and test errors in one repair process accounted for 50% of the total cost of repair, and contrary to what might have been expected, the cost of test errors was much higher than the cost of build errors. It is considered that such high repair costs due to test errors are a relatively recent phenomenon associated with most of the recent very complex avionics systems, and while already a serious problem, it will become even more serious as the general level of avionics complexity increases.

Toulouse, France, J. Lagasse, CNRS, Laboratoire d'Automatique et d'Analyse des Systèmes; Privat, Editeur, 1974, p. 305-320. In French.
Description of two techniques that have been developed to ensure a high probability of good operation of data processing systems used on board warships. The two techniques are complementary and are called automatic reconfiguration and continuous maintenance, respectively. Automatic reconfiguration consists in putting into operation degraded versions of the system when a breakdown occurs. This implies the definition of a hierarchy of operational functions which makes it possible to choose the functions to be abandoned in case of breakdown of an element of the system. Continuous maintenance consists, on the one hand, in real-time detection of hardware breakdowns and, on the other hand, in programmed localization of these breakdowns.

to their impact on future aircraft designs and their economic effect on the general-aviation industry. Since no type of certification requirements for noise abatement currently existed for propeller. driven aircraft (other than for those in the transport category), it was necessary to set up a testing procedure to determine how the standards could be modified for such aircraft. Discussed in detail are the noise evaluation measures, testing procedures, and maximum noise level standards.

Development of a procedure for performing critical analyses of preliminary designs of military aircraft, and review of the role of the laboratory in the preliminary design stage. It is noted that in the care of a military aircraft such a critical analysis is based on studies of the sensitivity of the aircraft performance to predictable or probable variations of the aerodynamic and power plant parameters. The need for an analysis of reliability and maintenance aptitude, leading to an estimate of repair and preventive maintenance costs, is stressed, as well as the need for flexibility of the design objectives. A review is made of analysis techniques based on parametric studies, prior experience, sophisticated calculations, test results, and intuition. A detailed account is given of the role of laboratory research in designing vertical-takeoff supersonic fighter, a short takeoff transport, ramjet propulsion, the Concorde SST, and a variable sweepback aircraft.

A74-30353# Federal aviation requirements for future air navigation improvements. A. B. Winick (FAA, Washington, 7.C.). In: National Radio Navigation Symposium, Washington, D.C., November 13-15, 1973, Proceedings.
Washington, D.C., Institute of Navigation, 1974, p. 13.17. 6 refs.
Aviation requirements for long distance navigation aids are based on the need to assure safe separation in high traffic density portions of the airspace. In domestic areas, a growing need appears to exist for a supplement to the standard short distance navigation system. A worldwide ground reference aid appears desirable as an adjunct to self-contained systems, and as primary device in other cases. Accuracy requirements are not extreme; reliability and suitability for cockpit operation have equal importance. The goal of a single ground-based system appears feasible, if agreement can be reached on common requirements and sufficient time is planned for an orderly transition.
Variables sampling and MIL-STD-414. E. G. Schilling (General Electric Co., Lamp Business Div., Cleveland, Ohio). Quality Progress, vol. 7, May 1974, p. 16-20.
The principal advantage of variables plans over attributes is reduction in sample size. Probably the most important consideration in applying variables sampling plans is the requirement that the shape of the underlying distribution of measurements to which the plan is to be applied must be known and stable. This means that statistical tests on past data must show that the distribution of measurements involved actually is that assumed by the plan. Control chart evidence also is desirable to indicate its stability. Military Standard 414 is an acceptable quality level (AQL) type sampling scheme that assumes underlying normality of distribution of the measurements to which it is applied. Since it is an AQL plan, it incorporates switching rules to move from normal to tightened or reduced inspection and return.
A74-30358 # Economical usage of long range navigation. W. K. Vogeler (Telcom, Inc., McLean, Va.). In: National Radio Navigation Symposium, Washington, D.C., November 13-15, 1973, Proceedings.
Washington, D.C., Institute of Navigation, 1974, p. 63-70. 5 refs.
A description of the operational requirements and economic factors which confront the low-cost user of long range navigation/ positioning systems serves as an introduction to the comparison of satellite, Omega, Decca, and Loran-C usage in the non-military area. Three categories of users are described: the direct user who desires to know his location, the analytic user who desires a documented record of his unit's track, and the controller who desires the location of other units. The four systems are then compared with respect to those considerations which are of importance from the user's viewpoint. Loran-C is selected as the system which best meets the user requirements. The manner in which Loran-C can be utilized with a description of industrial and governmental tasks concludes the paper.
Energy self-sufficiency · An economic evalua. tion. M. A. Adelman, H. D. Jacoby, P. L. Joskow, P. W. MacAvoy, D. C. White, M. B. Zimmerman (MIT, Cambridge, Mass.), and H. P. Meissner. Technology Review, vol. 76, May 1974, p. 22-58. Research sponsored by the Massachusetts Institute of Technology.
On the assumption that the U.S. meets all its energy demands from internal sources by 1980, forecasts are made of the prices at which supply and demand will be in equilibrium. The results indicate that prices in the range from $10.00 to $12.00 per barrel (oil-equivalent) will be necessary to bring forth enough additional supplies of fossil fuels to satisfy demands in domestic energy markets by that time. The development of special price policies is recommended for the synthetics industry. Security can be provided against import disruption by the introduction of radically new import policies. One important element would be an import storage program.

A74-32320 # Mariner Venus/Mercury '73 · A strategy of cost control. J. R. Biggs (NASA, Office of Space Science and Applications, Washington, D.C.) and W. J. Downhower (California Institute of Technology, Jet Propulsion Laboratory. Pasadena, Calif.). Astronautics and Aeronautics, vol. 12, June 1974, p. 48-53.
The Mariner Venus/Mercury '73 project kept within its originally established goals for schedule, performance, and cost. Underlying this development success was the availability of the Mariner technology. But meeting the goals demanded management determination, planning, and discipline to make optimum use of state-of. the-art technology. The present work points out management approaches and techniques that kept schedules and controlled costs, the intent being to stimulate thought about how to do the same with future spacecraft and payloads,
A74-33298 A proposed pricing procedure for domestic airlines. C. K. Walter (Nebraska, University, Lincoln, Neb.). Journal of Air Law and Commerce, vol. 40, Winter 1974, p. 61-74. 34 refs.
A tariff construction system for domestic airlines is proposed which it is argued is equitable to both passengers and airlines, logical, and programable for computation. The basis for determining fares would be the distance from origin airport to destination airport. A table of all commercial airports, their latitudes and longitudes, and some basic formulas would constitute sufficient information to determine the distance between any airport pair. The class of service would also be considered. This linear pricing system is simple, although possible arguments against it are also brought forward.
A74.32321 # Ground testing and simulation. I · Key to efficient development of aerospace systems. J. D. Whitfield (ARO, Inc., von Karman Gas Dynamics Facility, Arnold Air Force Station, Tenn.). Astronautics and Aeronautics, vol. 12, June 1974, p. 54, 55. 6 rets.
Future developments of aerospace systems can be carried out faster, safer, and at a lower cost through more complete and earlier ground testing and simulation. This requires a change in present development philosophies as well as the availability of more advanced facilities, such as highReynolds number transonic tunnels, large full scale subsonic tunnels, and propulsion facilities for testing very large turbine engines.
An analysis of the national transportation policy. S. D. Browne (MIT, Cambridge, Mass.). (Annual Air Law Symposium, 8th, Dallas, Tex., Mar. 14, 1974.) Journal of Air Law and Commerce, vol. 40, Winter 1974, p. 75.79.
The present work advocates greater central control of national transportation policy making, and states that Congress must address the problem of an all-mode transportation department with power to allocate resources between the modes. It is also pointed out that recent data concerning the fuel efficiency of various modes of transportation are out of line. It is argued that these data, obtained by dividing total passenger miles by total fuel, reflected badly on air transportation without taking into consideration actual trip distances, infrastructure costs, and time considerations.
European space activities since the war · A personal view. A. V. Cleaver. (British Interplanetary Society, Meeting. London, Mar, 8, 1974.) Spaceflight, vol. 16, June 1974, p. 220-238
If European collaboration is to be meaningful, an attempt must be made to subordinate national interests to the common aim. Long-term objectives must always be borne in mind; basic decisions can rarely be taken as a result of short-term cost-benefit analyses. Effective European collaboration is impracticable unless better political continuity can be assumed, with fewer changes of policy, delays in decision
making, and cycles of 'stop-go' decisions. Perhaps the only possible solution to the problem would be for European ministers to confine their own powers to laying down certain very broad but firm guidelines, thererfter leaving the implementation of such policies to the professionals within agencies and industry.
Dynamics and forecasts of R&D funding. C. E. Falk (National Science Foundation, Div. of Science Resources Studies, Washington, D.C.). Technological Forecasting and Social Change, vol. 6, no. 2, 1974, p. 171-189. 21 refs.
The relationships between U.S. R & D funding and other macroparameters are analyzed on an overall national basis and within the four major sectors of the economy. The study concentrates on the dynamics of the two largest funding sources, government and industry, which are examined at decreasing levels of aggregation, Various numerical relationships are demonstrated and explanations of observed dynamical interactions are presented. The effects of the introduction of new areas of R & D interest are investigated. Funding patterns are shown to reflect an inherent stability of R&D operations, as illustrated by lack of good, short-term correlations between R & D funding and cyclical variants such as profits in industry or science and engineering graduate enrollments in institutions of higher education.
