I have a D100 in my 6A. I noticed my altitude was off whenever I set my altimeter to a nearby AWOS or ATIS setting vs using field elevation. I found the setting that let's me put in an offset to rectify this issue (I needed a 70' correction). However, I use the D100 to feed my transponder. Is the offset being applied to the outgoing pressure altitude data?

My airport sits under a 1000 AGL shelf and I routinely bump up to it coming in and out of my airport. I am hoping that my transponder is sending out the correct altitude to avoid upsetting the ORD guys.

Not sure of the answer myself, but just call ATC and ask what they are seeing. I've done it before.

I also use the D100 as my encoder, but my GTX327 shows me what pressure altitude it is seeing/sending. If that is correct you're probably okay.

I'd check with Dynon support and/or get a transponder check. I just did mine for IFR reasons.

Yes the altitude offset/correction factor is applied to both the displayed and encoder outputs.
Just FYI, encoder output is ref'd to "standard" baro pressure of 29.92

Thanks Walt!
