Collins Aerospace ECU-3000 External Compensation Unit

The Collins Aerospace ECU-3000 External Compensation Unit is a remote-mounted calibration module engineered for high-performance business jets and corporate turboprops. Positioned adjacent to the flight deck's direction sensors, this module acts as a localized data filter that compensates for structural magnetic distortion caused by the aircraft's skin, wiring, and hardware. By feeding real-time correction profiles to the primary navigation computers, it ensures the flight deck displays true magnetic heading configurations.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 7/21/2026.

Key Technical Capabilities
  • Single Air Data Interface: Engineered as a dedicated single air data lane processor, optimizing signal filtering loops for a primary attitude and heading reference system (AHRS) loop.
  • Magnetic Calibration Storage: Houses internal non-volatile memory chips designed to hold aircraft-specific compensation coefficients gathered during standard compass swing ground procedures.
  • Pro Line 21 System Alignment: Synthesizes raw magnetic orientation data from the FDU-3000 Flux Detector and strips out localized electrical deviations before passing the corrected signal down the avionics bus.
  • Ultra-Compact Footprint: Packaged in an exceptionally lightweight, remote-install chassis measuring just 2.00″W x 1.43″H x 2.82″L and weighing roughly 0.2 lbs, making it easy to fit into tight tail cone or wing tip sensor bays.
  • Environmental Isolation: Built within a sealed metal shell constructed to survive severe temperature swings and heavy structural vibrations in unpressurized locations of the fuselage.
