This document consists of three volumes. "Volume I: User Priorities for the National Airspace Redesign" is a summary of user comments from six recent meetings held throughout the United States. "Volume II: High Altitude Airspace Concept" defines how one segment of the NAS could provide more of the freedoms described in the Free Flight Concept while permitting transparent operation for aircraft entering from and leaving to adjacent airspace. "Volume III: Recommendations on Special Use Airspace in National Airspace Redesign" identifies known types of airspace users and describes how each of the current and future users is affected by special use airspace.
