To improve heading accuracy and consistency for your uAvionix AV-30-C add an AV-Mag. AV-Mag external magnetometer is a 3-axis electronic compass. AV-Mag precisely measures the earth’s magnetic field and aids the AV-30 directional heading measurement, improving long-term accuracy and consistency.  The AV-MAG-STC for certified aircraft is currently on pre order with orders expected to ship in the spring of 2023.  Current pre order pricing is USD $299 for the AV-MAG (certified).
