The Federal Aviation Administration (FAA) Research, Engineering, and Development (RE & D) Plan addresses the present and future needs of the national aviation system through fulfillment of the FAA's major mission areas. The purpose, scope, and primary objectives of the plan are presented in Chapters 1 through 4 of Volume I. This volume contains detailed descriptions of the projects included in the RE & D Plan. For planning purposes, the time frame is broken into three 'windows', with 1989 to 1995 composing the near term, 1996 to 2005 the mid-term, and 2006 to 2015 the far term. The project plans described in this volume have been organized into the following 13 technical areas: system studies, air traffic control, communications, navigation and landing, surveillance, aviation weather, satellite applications, airborne systems, airports, aircraft safety, aviation medicine, security, and human systems and operations.
