Information About 4020577-3
The 4020577-3 is a Honeywell directional gyro designed as a fully self-contained heading reference solution for aircraft compass systems. It houses the gyro, amplifier, and synchronizer within a cylindrical enclosure, with a DC static inverter mounted in the base to supply AC power to internal and external system components. The unit includes two independent heading transmitters that provide 3-wire ARINC heading information to separate systems simultaneously. It is electrically driven and engineered to meet TSO-C6c and TSO-C6e requirements, ensuring compatibility with certified aviation navigation architectures.
Key Features
- Integrated Gyro And Amplifier Assembly: Combines gyro, amplifier, synchronizer, and inverter into a single compact unit for simplified installation.
- Dual Heading Transmitters: Provides redundant 3-wire ARINC heading outputs to support two independent systems.
- DC Static Inverter: Supplies stable AC power for the gyro synchronizer and connected external components.
- Wide Gimbal Freedom: Supports ±85 degrees horizontal and 360 degrees vertical movement for stable operation in dynamic flight conditions.
- Accurate Slaved Operation: Maintains heading accuracy within ±2 degrees with controlled slaving rates.
- Electrically Driven Design: Ensures consistent performance without reliance on vacuum systems.
- Certified Performance: Meets TSO-C6c and TSO-C6e standards for aviation compass system applications.
The 4020577-3 delivers the reliability and precision required for continuous heading reference and navigation support in certified aircraft compass systems.
