The workshops were initially sponsored by NASA, NOAA and the FAA, and were later joined in sponsorship by DOD and the Office of the Federal Coordinator. They have provided a forum for open discussion of weather and environmental concerns between the research, operations and user organizations within the aviation community. Following the past few workshops, several individuals have voiced concern over the benefit of what has become a continuing workshop with in many instances the same continuing recommendations. To assess the value of a continuing workshop one must look beyond a simple comparison of recommendations made year to year. Although problems appear very rapidly, such as those resulting from an accident, solutions usually span many years and involve time-consuming activities such as funding cycles, studies, experiments, and cooperation from multiple organizations. The values I would give high marks to are in programmatic guidance and communication. Over the history of this workshop I have seen programs within my own organiza- tion NASA initiated and/or guided from information gained here at Tullahoma. The task of communicating is difficult when people are on the same side of an issue; it is almost impossible when requirements of operators, researchers, and users are debated before the Congress or the public in a competitive environment. The continuing Workshops on Meteorological and Environmental Inputs To Avi- ation Systems provide a needed non-competitive atmosphere for open discussion of aviation problems and a critique of ongoing activities from a diversified, but involved audience.

The first one was held in March 1977 and the last in March 1985. These workshops have served a twofold purpose for the gov- ernment sponsors (NASA, FAA, NOAA, DOD, and OFCM). Their first purpose was to bring together the various disciplines of the aviation community with atmospheric scientists and meteorologists in interactive discussions concerning needs of the community and how to satisfy these needs. Their second purpose was to use the established and identified needs to develop recommendations that serve as a basis for structuring relevant programs of the sponsoring agencies. An indication of how well the purpose of these workshops has been achieved is given in the various reports, papers, and presentations that have been made on the workshops (Camp and Frost, 1977, 1979, 1981, 1985a, 1985b; Camp, et al. 1980a, 1980b, 1981; Frost and Camp, 1978, 1980, 1982, 1983, Frost, et al. 1979a, 1979b; and Miller, 1987; [I-161. Due to the coverage of the previous workshops, this article will be concerned only with the results (recommendations) of the seventh workshop. Workshop Structure and Operation The basic objective of all the workshops has been and is to satisfy the needs of the sponsoring agencies relative to such factors as 1) Knowledge of the inter- action of the atmosphere with aircraft and airport operations, 2) Better definition and implenlentation of meteorological services for the operators. and 3) The col- lection and interpretation of data for establishing operational criteria relating the total meteorological inputs from the atmospheric sciences to the operational and educational needs of the aviation community. The specific theme of each workshop gives an insight into its particular focus. "Aviation Weather/Observing, Distributing, and Using the Products" was the theme for the Eighth Annual Workshop on Meteorological and Environmental Inputs to Aviation Systems. This workshop theme, coupled with the focusing of the interactive committees, according to the committee titles (Table I), tended to direct the workshop in the desired area of effort. These interactive committee sessions are considered to be a major element contributing to the success of the annual workshops. The type of information desired from the interactive committee sessions was what was the effect of the particular subject area (Fixed Committee Title) on the operation of the various segments (Floating Committee Title) of the aviation community? Each of the committees was asked to focus its discussion according to the committee guidelines given in Table 2. The workshop began with a series of five overview papers (Table 3). Papers on previous workshop accomplishments, interactive weather displays, and impromptu tasks were also given. These also helped to set the tempo in the vein of the workshop theme, as did the banquet and dinner presentations. The structure (program) of this workshop was very similar to previous workshops. It began with the overview presentations, followed in order by interactive committee sessions, banquet, impromptu presentations, more interactive committee sessions, dinner presentation, more interactive committee sessions, and a conclusion with a plenary session consisting of the committee chairmen presenting the results and recommendat ions of their committees. Comments and Recommendations At this workshop, the committee chairmen were requested to use a special procedure (form) for reporting their comments and recommendations. Specifically, they were asked to give the results of their efforts in the following order: 1) state as concisely as possible the issue, 2) briefly summarize the discussion of the issue, 3) state recommended action, 4) indicate who should be responsible for accomplishing any required effort, and 5) specify the priority of issues discussed.
