Jim, any contingency for losing all power to the aircraft, may be the reason the Dynon failed? Compass, Map? I just pose the question since you have provided a scenario that I have been contemplating recently as I wire this thing and think of a backup radio. If one has no map available I suppose your phone is a good resource for at least outdated maps. In fact my iPhone has a compass also but I don't know how accurate it will be inside the airframe. It also has a nifty bubble level that I wonder how helpful it could be to orient the attitude of an airplane? Back on subject. I was hoping to see the new iCON A25 at the AS customer appreciation day event where the iCON vendor was showing a bunch of their stuff but would you believe they didnt have the newest product. I have owned iCON stuff in the past and liked it.
