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...

I believe you will need to repeat the backup battery test to remove that alert.

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...

There's no real substitute or shortcut for RTFM.

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.

Interesting, good to know. Thanks for reporting back.

That's getting into the arena of an instrument approach, giving guidance all the way to the runway. Unlikely you'll get that from Dynon.

Yep, for VFR only work, there are other options.

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.

From the install manual - Tachometer pulses/revolution are set in the Engine Information Wizard – SETUP MENU > HARDWARE CALIBRATION > EMS CALIBRATION > TACHOMETER CALIBRATION.

Same here with the GPS 1 message, no clue as to how/why/who/when/where

Agreed - I typically fill within .1 to .2 of what the fuel computer thinks I will need.

Garmin is shuttering their 430/530 line. I replaced my 430W with Avidyne IFD440 a few years ago and absolutely love it - the user interface with Avidyne is so much better than Garmin. Any of them will interface with the ARINC-429 device to feed nav data to the Dynon - but you really want to...

What specifically is showing up with red X's? Can you post a picture of it?

You've replaced the ARINC itself, and the data cables in/out - what about the power and ground? Verify those are good, including any breaker/switch the power is coming from.

And MikeD brings in RTFM for the ultimate win! :p

I was thinking (memory) that the default was 68000 for the K-factor. Either one will get you in the ballpark and let you adjust from there. Now fill the tanks completely full and go fly. The longer the better, burn as much fuel out of the tanks as you are comfortable with, landing near empty...
