This conference proceedings document is the latest step in the FAA's continuing iniative to improve the usefulness of its aviation forecasts for decisionmaking and planning by the aviation community. It attempts to capture the commentary from participants at the Third Annual FAA Forecasting Conference (December 1977--Reston, Virginia) and to summarize FAA responses. The document is organized into two parts. Part I, Forecasting Initiative Overview, discusses commentary from the aviation community, followed by the FAA response. Part II, Proceedings, presents remarks by conference participants. In total, this document updates the dialog between the FAA and members of the aviation community and general public in the joint effort to define the most useful and appropriate aviation forecasting system.
