As Rich says, it's something that we've seen from a few customers, and are looking into the root cause to figure out how we can provide a better experience here.
Hi!
A small report primary for Dynon Support:
I made my first longer x-country today 2 times 3 hours, most of the time with the AP engaged. My equipment is AVMAP EKP IV and EFIS D-100 + AP74. On the first leg I think we got the NavSource log message about 11 times and some fewer on the return leg. Always able to reenable by pushing NAV btn within a few seconds.
But whats bothers me is that every time the TRK mode engaged the airplane tried to roll and turn quite violently to the side were heading bug was. Shouldn't she AP continue on present TRK from the GPS? Or does the AP lose track info momentarly from the GPS as well?
Trying to realigning the heading bug with the TRK indication lessened those rolls/turns.
But every few times even this didn't helped as I realized that when the Nav Source lost message appeared the heading bug was moved to some other heading way off. I wasn't able to see if it was by 180 degrees or some other value.
Any ideas?
Thanks for a impressive product otherwise.
Best Regards,
Andreas Glöckner
Sorry, lost a few lines on my copy/paste. fixed. Yes this Garmin has about 5 mode combos to choose from. I'll try to fly tomorrow and see what I can document, what MNEA group holds the nav source.Are those two different modes that have different groups of sentences? In any case, the second group doesn't have the required sentences in it, period. See http://wiki.dynonavionics.com/GPS_Serial_Compatibility_and_Configuration_Settings for what we need for basic GPS data and GPS NAV.
I'm using a Garmin 496 to drive my Dynon AP. Occasionally I will see an error saying something like "NAV source lost".
Is this normal behavior? I'm told by one of the beta testers that this is because the 496 is prone to dropping packets.
