A NASA Ames R & D (research and development) simulator was utilized through the development phase of the F-14A program and on a continuing basis into the T & E (test and evaluation) phase. This utilization has concentrated on development and evaluation of the APC (approach power compensator), AFCS (automatic flight control system), and ACLS (automatic carrier landing system). The importance and success in the use of this simulator during the T & E phase is discussed with respect to accuracy of duplicating and predicting flight test results, pilots' acceptance of the simulator as a valid representation of the real aircraft, and cost effectiveness for reducing flight time while increasing flexibility. The success of this program has led to the adoption of a similar approach for APC, AFCS, and ACLS development for the S-3A aircraft and for reevaluation of the A-TE ACLS capability.

In previous investigations, attempts were made to isolate the most critical skills and procedures within each stage of replacement air group (RAG) training in the F-4 aircraft. For each of the stages analyzed, a small set of items were selected on the basis that they could discriminate among replacement pilots according to their final RAG grade. On the basis of these isolated skills, two fleet evaluation questionnaires were developed to be used by operational F-4 squadron commanders. In addition to ratings on these two rating forms, squadron commanders were asked to report critical incidents. These included such occurrences as accidents, incidents, and wingspulled. Data obtained from these two forms were used as the criterion measures in the investigation. Selected test scores and flight grades from undergraduate pilot training were used as potential predictors. These were related to the criteria in a series of correlational and regression analyses. A number of significant relationships were obtained among the performance measures. Such results indicated the method used in developing the rating form to be a feasible one. Implications are discussed in terms of potential use for actual assignment of aviators to RAG training in the F-4 aircraft.

Science, the overwhelming concern of our timo, is no longer a matter of private research and development but one of public policy and administration, in which government, industry, foundations, and educational institutions must all work together as never before. Few other single tasks are of such decisive importance to the collective and individual welfare of American citizens as the formulation of public science policy and the administration of scientific programs. Eleven national authorities of varied background in science, education, and government administration contribute their experience and their judgment in an effort to deal with the major aspects of the subject. Their focus is on the meeting of actual problems, they consider the decision making process in both public and public-private organizations. Topics are grouped in three general categories: personnel needs and resources, organizational problems and techniques, and the administrative role in policy leadership.

The author has identified the following significant results. A Coastal Zone Surveillance Program has been developed in which systomatic comparisons of early ERTS-1 images and recently acquired images are regularly made to identity areas where changes have occurred. A methodology for assessing and documenting benefits has been established. Quantification of benefits has been directed toward four candidato areas: shore protection, ocean outfalls, coastal land resources, and offshore waste disposal. A refinement in the change dotoction analysis procedure has led to groater accuracy in spotting developmental changes in the Coastal Zone. Preliminary conclusions drawn from the Shore Erosion case study indicate that in the northern test area (developed beach) erosion has occurred more often, is generally more severe, and the beach is slower to recover than in the southern test area (natural beach). From these data it appears that it may be possible to defino areas most likely to experience further erosion. The assumption of continued erosion in areas that have at one time experiencod severe erosion is supported by the simplo fact that as a beach narrows wave energy is concontratod on a narrower beach surface. The higher onorgy condition subsequently results in accelerated erosion.
