Freedom 2
The Freedom 2 system is a modern, drop-in replacement for legacy digital AHRS units in aircraft already equipped with a digital Air Data Computer and ARINC 429-compatible avionics.
Freedom2 is ideally suited for platforms seeking a contemporary AHRS solution—such as those currently using systems like the LCR-93 in the Learjet 45 and similar aircraft. With a compact footprint and robust digital output, this package offers improved accuracy, reliability, and long-term support—without requiring changes to cockpit layout or aircraft structure.
Ideal For Aircraft That:
- Already utilize a digital Air Data System
- Require ARINC 429 data outputs for flight instruments, flight directors, or autopilots
- Are transitioning to newer-generation inertial solutions while maintaining cockpit compatibility
Freedom 2 Package Contents
- Two (2) AHR75 Attitude and Heading Reference Systems (AHRS)
- Two (2) AHR150A-2A Magnetometer Sensor Units (MSUs)
- Mounting plates and adapter harnesses for straightforward installation
Advantages
- Long-term availability and support
- Increased system reliability and uptime
- Reduced maintenance costs and downtime
- Seamless integration with modern avionics suites
With Freedom2, operators can upgrade aging avionics infrastructure with confidence—enhancing performance and maintainability while preserving certification paths and cockpit functionality.
Legacy Vertical Gyro (VG) and Directional Gyro (DG) systems are facing increasing obsolescence, resulting in costly repairs, reduced reliability, and extended downtime. Recognizing the need for a modern replacement solution Archangel Systems has developed two convenient packages – Freedom 1 and Freedom 2 – each targeted at a specific avionics configuration.
- Two (2) AHR75 Attitude and Heading Reference Systems (AHRS)
- Two (2) AHR150A-2A Magnetometer Sensor Units (MSUs)
- Mounting plates and adapter harnesses for straightforward installation
- Dedicated adapter harness & mounting plates simplify installation.
- Smaller & lighter than existing VG/DG.
- Provides an economical RVSM capable digital Air Data solution.
- Mounts on most previous DG\VG locations, no structural mods required.
- Entire system provides an increased MTBF, resulting in reduced downtime.
- Option to add more A429 devices in the future (Cockpit modernization)
