  • 5-1-2. ALIGNMENT ACCURACY CHECK

    TERMINAL

    1. At locations not equipped with Digital Terminal Automation Systems (DTAS), during relief briefing, or as soon as possible after assuming responsibility for a control position, check the operating equipment for alignment accuracy and display acceptability. Recheck periodically throughout the watch.
      • REFERENCE
      • FAA Order JO 7210.3, Chapter 3, Chapter 8, Chapter 9, Chapter 10, and Chapter 11.
      • Comparable Military Directives.
      1. Check the alignment of the radar video display by assuring that the video/digital map or overlay is properly aligned with a permanent target of known range and azimuth on the radar display. Where possible, check one permanent target per quadrant.
      2. Accuracy of the radar video display must be verified for digitized radar systems by using the moving target indicator (MTI) reflectors, fixed location beacon transponders (Parrots), beacon real-time quality control (RTQC) symbols or calibration performance monitor equipment (CPME) beacon targets.
        • REFERENCE
        • FAA Order JO 7210.3, Para 3-7-1, Tolerance for Radar Fix Accuracy.
      3. Digital Terminal Automation Systems (DTAS) conduct continuous self-monitoring of alignment accuracy; therefore, controller alignment checks are not required.
