Flight Investigation of Cockpit- Displayed Traffic Information Utilizing Coded Symbology in an Advanced Operational Environment

Abstract: : Studies initiated during the early 1970's provided initial exploration of traffic-situation display concepts in a simulation environment During the present study, the traffic symbology was encoded to provide additional information concerning the traffic, which was displayed on the pilots' electronic horizontal situation indicators (EHSI) The purpose of this study, which was conducted using a research airplane representing an advanced operational environment, was to assess the benefit of coded traffic symbology in a realistic work-load environment Traffic scenarios, involving both conflict- free and conflict situations, were employed Subjective pilot commentary was obtained through the use of a questionnaire and extensive pilot debriefings These results grouped conveniently under two categories: display factors and task performance A major item under the display factor category was the problem of display clutter The primary contributors to clutter were the use of large map-scale factors, the use of traffic data blocks, and the presentation of more than a few airplanes In terms of task performance, the CDTI was found to provide excellent overall situation awareness Additionally, the pilots expressed a willingness to utilize lesser spacing than the 2 1/2 nautical mile separation prescribed during these tests

Combat Operations Decisionmaking in Tactical Air Command and Control

Abstract: : This note examines the Combat Operations function in tactical air command and control, and explores some of the human and organizational issues related to the use of technology (particularly automation) to support and enhance that function. Command and control of tactical air power involves a combination of people and technology, principally communications and data processing technology, In this note, 'people' issues, and the relationships between the human organizations which comprise the command and control system and the technical systems which support them are examined. The authors focus on the command and control process occurring in the Combat Operations section of a Tactical Air Control Center (TACC). This includes monitoring and managing planned air operations as they occur, and modifying those operations to adjust to changing circumstances. TACC can be thought of as a decisionmaking entity in which incoming information about the state of an ongoing conflict is used to manage the employment of airpower resources. (Author)
