uAvionix has introduced the AV-Mag, a 3-axis external magnetometer for AV-30 panel displays.
When paired with an AV-30, Av-Mag will provide “consistent and accurate magnetic heading information,” according to company officials.
“With its ability to precisely measure the earth’s magnetic field and aid the AV-30 directional heading measurement, AV-Mag offers the long-term high-accuracy Directional Gyro (DG) solution that pilots have requested,” officials add.
Pilots have the option to allow AV-30 to use the magnetic compass data from AV-Mag, rather than manually setting the DG to compass heading, company officials noted. Pilots who want to use the AV-30 as a traditional user-adjusted DG can override the measured magnetic heading and set a specific heading for aerobatic maneuvers or other practice procedures, they add.
AV-Mag for experimental aircraft is available now for $249. AV-Mag for certified aircraft is pending STC/PMA certification and is expected to begin shipping in spring 2023.

At the dawn of aviation Piper hooked the DG to drive the Piper IIIb autopilot. The IIIb is all the autopilot I want but I want your stuff. Someone in MT, much more intelligent than I, surely can figure out a way to have your DG drive the autopilot IIIb. Please, please get someone on this. Thanks
A great piece of equipment already and now adding the magnetometer it is better yet.
