Frequently Asked Questions - AHRS-1 MGL Avionics
What is the AHRS-1 used for?
The AHRS-1 is a solid-state Attitude Heading Reference System that provides pitch, roll, heading, slip, and rate of turn for aircraft instruments and autopilots.
How do I install the AHRS-1 in my aircraft?
Mount the unit using the included bracket in a location with minimal vibration and magnetic interference. Connect power (9-32V DC) and data buses per the installation manual. Perform a magnetic calibration after installation.
Does the AHRS-1 require calibration?
Yes, initial magnetic calibration is required to compensate for the aircraft's magnetic signature. Follow the procedure in the user manual; recalibrate if components are moved.
Can the AHRS-1 interface with my existing avionics?
The AHRS-1 outputs data via RS-232, ARINC 429, and analog formats. It is compatible with most MGL and third-party EFIS, autopilots, and flight instruments. Check specific interface requirements in the manual.
How do I update the firmware?
Download the latest firmware from the MGL Avionics website, load it onto a USB drive, insert into the AHRS-1, and follow the update procedure in the manual. Ensure power is stable during update.
What is the accuracy of the AHRS-1?
Typical accuracy is ±0.5° for pitch and roll, and ±1° RMS for heading after proper calibration. Performance degrades during excessive acceleration or magnetic interference.
How do I troubleshoot a 'no data' issue?
Check power supply voltage (9-32V), verify wiring connections, ensure baud rate and protocol match your display, and run the built-in self-test. Refer to the troubleshooting section in the manual.
Is the AHRS-1 certified for IFR flight?
The AHRS-1 is TSO certified (C4c, C10b, C16e) and compliant with DO-178C/DO-254, making it suitable for IFR operations when installed in accordance with the installation manual.
What maintenance is required?
No routine maintenance except periodic firmware updates and cleaning of connectors. The unit has no user-serviceable parts; return to MGL for repair if defective.
Can I use the AHRS-1 in a helicopter?
Yes, but ensure that vibration isolation is adequate and that magnetic calibration is performed in the helicopter's magnetic environment. The AHRS-1 works in both fixed-wing and rotorcraft.
