I've had this before - and with one exception, it was because the USB stick itself was getting so hot it failed to function. In my experience the SanDisk Ultra 32gb 3.0 drives give the best performance, I have very few problems with them.
The very small form factor USB sticks are great for...
Kinda depends on your mission. If you are "IFR Lite" and don't mind cancelling a trip once in a while for true low ceilings where you are going, then sure the G175 will serve the great majority of your needs. Many RNAV approaches will not go below 400' ceilings, and you'll need a true ILS to get...
John has good advice above - I've lost an ADAHRS unit before, in flight. It happens.
Something interesting occurs as well with the Dynon if your pitot ices up - your pitch horizon goes nuts for a minute or two as the system is "anticipating" what your airplane is supposed to be doing based on...
While accurate, that answer is not helpful for the question because it is incomplete.
Certified aircraft are not allowed to use non-certified avionics, but experimental aircraft are. Exceptions apply such as IFR navigators, ELT's ,and transponders.
Yes, please define "can't get it to take".
If the backup battery is not fully charged it will not allow you to start the test. The battery charges through SkyView, and needs full system voltage applied to the Skyview (greater than 12.25 volts) before the backup battery will begin to charge. You...
Same experience here with the procedure turns, using both the Garmin 430W and the Avidyne 440. The procedure turn is shown on the map of the navigator if you zoom in to that level, but does not display on the Dynon. The rest of the flight plan displays on the Dynon just fine, but apparently the...
You are using the 470, not the 472, correct? I'm not sure you'll have the same upgrade path available for the firmware on the 470, which was discontinued many years ago and replaced with the 472.
Actually if you use Seattle Avionics database manager to update your charts on the USB sticks, it does now include the latest obstacle database from Dynon. That's a relatively recent change, maybe the last year.
