uAvionix on June 1 introduced the AV-Mag, a 3-axis external magnetometer, for AV-30 panel displays. AV-Mag, when paired with an AV-30, will provide consistent and accurate magnetic heading information.

With its ability to measure the earth’s magnetic field and aid the AV-30 directional heading measurement, AV-Mag offers what uAvionix describes as a long-term, high-accuracy Directional Gyro (DG) solution that pilots have requested.

Optimal performance of AV-Mag is achieved by innovative calibration and measurement techniques, explains uAvionix, including precise integration of attitude and magnetic field data in all orientations, and the use of the World Magnetic Model (WMM) to aid in calibration. Added features like Wind Direction and Speed are planned for an upcoming release.

With AV-Mag, pilots have the option to allow AV-30 to utilize the magnetic compass data from AV-Mag, rather than manually setting the DG to compass heading. Pilots wishing to use the AV-30 as a traditional user-adjusted DG can also override the measured magnetic heading and set a specific heading for aerobatic maneuvers or other practice procedures.

AV-Mag supports a number of installation orientations with the ability to wire and mount in a location away from ferrous metals or magnetic interference, ideally in the tail or either wing.
