My GPS III Pilot usually tells me that the winds are blowing 99 knots from some direction or another. I see this when I use the E6B function within the GPS. Now that I have a Dynon EFIS, I see the same kinds of big numbers reflected there. Has anyone seen this. I have been guessing that it has to be related to calibration of indicated heading. The GPS heading and speed must be right. My indicated airspeed agrees with other pilot's reading when I fly formation with them so I assume that is right. That leaves heading. But to get a huge wind speed like 99 knots, my heading would have to be way off, right?
Has anyone else seen this?
