Re: AV-30-C
I went for the AV-30 (to keep up with the Woods
) for ADSB out and kept my DG. On average about every 20 min to true it up. I often forgot to do it and if I had to rely on it suddenly, I might end up be going in the opposite direction. In reality, I use foreflight, following along with maps and compass.

Re: AV-30-C
Mine is sometimes 10 degrees, often 20, occasionally 45 or more. I just wired a little GPS puck up to the serial in, ground track is what I really use anyway.mmcmillan2 wrote:How many degrees off is it after 20 min?
