Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 9/23/2026.

• System-Driven Signal Conversion: Converts analog X/Y-axis deflection signals and RGB video inputs from an external SG-465 Symbol Generator into calibrated cockpit symbology. 
• Role-Configurable Operation: Architected for multi-role field assignment, allowing the hardware to be configured as an Electronic Attitude Director Indicator (EADI), an Electronic Horizontal Situation Indicator (EHSI), or a dedicated Multi-Function Display (MFD). 
• Enhanced Symbology Rendering: Features a larger footprint and an advanced raster/stroke writing scheme that renders larger text characters and flight symbols than preceding legacy ED-551 architectures.
• Isolated Power Bus Routing: Draws operating current directly from the aircraft’s 27.5 VDC power bus rather than pulling current from the external symbol generator, preserving system-wide electronic isolation.
• Thermal Regulation Monitoring: Features an internal fan blower managed by a dedicated internal airflow sensor. The sensor triggers an immediate automated error annunciation on the CRT screen if insufficient cooling velocity is detected.
• Weather Radar Overlay: Decodes multi-channel video data paths to overlay real-time color weather radar sweeps directly across active EHSI or MFD navigational maps.
• Environmental and Compliance Ratings: Certified to FAA TSO-C113 specifications with structural hardening against extreme environmental variables up to a maximum operating ceiling of 55,000 feet.
