      <title>CENTRAL FLOW CONTROL MANAGEMENT AIDS CODE AUDITOR (MACA) DATA ITEM DICTIONARY. USER'S MANUAL</title>
      <link>https://trid.trb.org/View/89050</link>
      <description><![CDATA[This document describes the functions of the Data-Item Dictionary (DID) generation programs and details the procedures required to exercise them. The purpose of the DID programs is to build a dictionary of all COMPOOL items and provide a cross-reference listing of items and modules, showing item-set and/or item-use information. The dictionary is printed on a table basis, and is primarily intended for use by maintenance programming personnel. (Author)]]></description>

      <title>EVALUATION OF DAIS TECHNOLOGY APPLIED TO THE INTEGRATED NAVIGATION SYSTEM OF A TACTICAL TRANSPORT</title>
      <link>https://trid.trb.org/View/143789</link>
      <description><![CDATA[This effort has provided an independent contractor assessment of the DAIS executive software, industry exposure to the J-73 level one compiler and DAIS software development tools and a definition of the interface between DAIS and integrated navigation systems. A combination of INS, GPS and air data was used to demonstrate the usefulness of the DAIS/integrated navigation system for tactical air drop and terminal area operations w/transport aircraft. A Boeing Aerospace Lab Simulation jointly managed by AFAL and Boeing, was conducted for the purposes of evaluating the DAIS/integrated navigation system software performance capabilities in a simulated tactical air drop and terminal area navigation flight profile. A 'Hot Bench' simulation was conducted using contractor developed sensor software modules and navigation filter, and the DAIS executive software and processing hardware. Outputs of the program include: Verification of the overall DAIS concept, measurements of executive software overhead and suggestions for improving the DAIS executive software.

      <title>COLLISION RISK AND ECONOMIC BENEFIT ANALYSIS OF COMPOSITE SEPARATION FOR THE CENTRAL EAST PACIFIC TRACK SYSTEM</title>
      <link>https://trid.trb.org/View/57557</link>
      <description><![CDATA[This report presents an evaluation of the application of composite separation to the Central East Pacific (CEP) track system. Criteria for the evaluation were a collision risk and an economic benefit's comparison of the existing four-route and proposed composite six-route systems. A 6-month data collection was performed. Radar data from land-based facilities in California and Hawaii and from Ocean Station Vessel November were processed to determine aircraft navigation performance. Utilization of the existing system was gauged from air traffic control facility data, and flight crew survey forms were used to collect information necessary for comparative analysis purposes. The report describes estimation of collision risk model parameters from the data. Lateral, longitudinal, and composite collision risk model risks were estimated for the existing and proposed composite systems based upon accepted North Atlantic Systems Planning Group (NAT/SPG) methodology, while vertical collision risk was calculated based upon previous NAT/SPG studies. Lateral collision risk for the proposed composite system was found to be lower than for the existing structure. Comparisons of fuel burn and flight times indicated that the proposite composite system would be more economically beneficial than the existing route configuration. As a result of the study, the proposed composite system was recommended for implementation on a trial basis. (Author)]]></description>

      <title>AIRPORT IMPROVEMENT TASK FORCE DELAY STUDY: DELAY MODEL VALIDATION PLAN</title>
      <link>https://trid.trb.org/View/69538</link>
      <description><![CDATA[A validation plan is presented for an airside simulation model. The plan stresses basic principles of validation and inherent problems associated with comparing simulation model delay estimates with observable real-world data. A methodology is proposed that consists of three major steps: (1) evaluation of model logic, inputs, and outputs; (2) comparison of model estimates with collected data; and (3) a sensitivity analysis of the delay simulation model. A Model Validation Group, established to oversee the validation process, is described. Suggestions are given on sources of data on airside operations for model inputs and for comparisons with model estimates. (Author)]]></description>

      <title>THE IMPACT OF A PROPOSED ACTIVE BCAS ON ATCRBS PERFORMANCE IN THE WASHINGTON, D. C., 1981 ENVIRONMENT</title>
      <link>https://trid.trb.org/View/57946</link>
      <description><![CDATA[A computer model of the proposed active Beacon Collision Avoidance System (BCAS) was developed to investigate the impact of BCAS on the Air Traffic Control Radar Beacon System (ATCRBS) ground system. Predictions were made for the early 1981 Washington, D.C., environment. Two ground environments were simulated, an all-ATCRBS environment and a 25%/75% Discrete Address Beacon System (DABS)/ATCRBS mix. Airborne fruit rates and the effect of BCAS/DABS mode power programming on interference were also predicted. (Author)]]></description>
