New heavy-haul freight aviation (Une nouvelle aviation de transport lourd). J. Bertin (Société Bertin et Cie., Plaisir, Yvelines, France). L'Aéronautique et l'Astronautique, no. 46, 1974, p. 2-8. In French.

Air Freight today is taken care of with aircraft whose performances are designed to suit passenger transport. Speed increase has led to fly non stop at high altitude, and thus to carry a fuel load higher than the actual payload. For freight however aircraft flying at 200 Knots would be perfectly adapted; they could then fly at low altitude, stop on the way and carry a payload much more important than their fuel capacity. To be economical such aircraft must be large (1000 ton or more) and air cushion landing will become a necessity. Numerous tests effectuated on the Bertin air cushion landing for air-drop platform have been most encouraging. To transpose this technique to aircraft landing is very straight forward. (Author)

Establishing airport cost and revenue functions. R. S. Doganis (Politechnic of Central London, London, England) and G. F. Thompson (Open University, Bletchley, Bucks., England). Aeronautical Journal, vol. 78, July 1974, p. 285-304. 10 refs.

The findings of a detailed financial and economic analysis of eighteen of the larger British airports are given. These findings are a tentative step in the building up of a theory of airport economics, a field much neglected by transport economists. The analysis is based on detailed traffic and financial data compiled from questionnaires and as a result of direct visits to all the airports in the sample. In fact, the eighteen airports covered are more than a mere sample, since taken together they account for about 95% of the air transport movements, of the passengers handled and of the freight traffic of all the United Kingdom airports outside the Channel Islands. The financial background, long-run airport cost functions, analysis of airport revenues, airport costs and revenues brought together, and the impact of competition on airport economics are considered.

The Skylab was basically a scientific program, and had the physical capacity for a large number of experiments. The number, weight, complexity, and size of these experiments far exceeded that of those on any previous manned space flight. The Apollo Telescope Mount was the most sophisticated and complex device ever to perform intensive studies of the sun above the restrictions imposed by earth's atmosphere. The demands these experiments made on Kennedy Space Center resources were varied and difficult, since each was virtually unique and imposed its own requirements. A management system to handle these responsibilities was devised and implemented, based on KSC experience with the Apollo and other prior programs. (Author)

Development innovations for Skylab student experiments. R. L. Gause (NASA, Marshall Space Flight Center, Materials and Processes Laboratory, Huntsville, Ala.). American Astronautical Society, Annual Meeting, 20th, Los Angeles, Calif., Aug. 20-22, 1974, Paper 74-152. 15 p.

The Skylab Student Science Program was an effort on the part of NASA and the National Science Teachers Association (NSTA) to provide the youth of America an opportunity to directly participate in space research. Students across the nation submitted proposed experiments which were scientifically evaluated by the NSTA. From the more than three thousand experiments submitted, twenty-five of the most innovative and novel experiments were selected for flight. Many of these required the development of flight hardware in order to perform the experiments aboard Skylab. The requirements placed on the hardware in terms of cost, development time, weight, volume, and crew training represented a unique challenge to the NASA engineers and scientists involved in the design, development, fabrication and testing of this hardware. To meet these stringent requirements required innovative changes in the classic Skylab approach to experiment development. (Author)

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. Author (GRA)
