Garmin recently published Service Advisory 20112 Rev A stating that the AHARS magnetic model expired and needs to be updated. The GI-275 is supposed to give you the option to update it when you install a new nav database, but mine did not. Garmin was worthless answering the basic questions of why it didn’t work and how to fix it, and even more worthless when asked if it impacted the airworthiness of the instrument. Does anyone know if there are any issues flying with a GI-275 installed as Primary HSI with an out of date AHARS magnetic model? It is just a white message on the GI-275 and their Advisory Circular did not mention anything about being un-airworthy, but I want to check since Garmin was clueless on how to make it update. Thanks.
