Good Evening Skip,
Do you intend to have only the Dynon for altitude information?
I will not be flying IFR without having a standard altimeter for reference, but that is part of my risk assessment.
Here is my thought trail.
What harm will befall me if the Dynon sends false information to the transponder?
Or, --- What harm will befall me if the Dynon does not send any data to the transponder?
When I have had a transponder send bad data (From fully certified and TSO'd equipment by the way) to the FEDs, they have told me about it and asked that I turn off the altitude function.
So far, that has seemed to be within the acceptable risk that I am willing to take.
Whadda Ya think?
Happy Skies,

Well, how does one decide that the real physical risk of a non-TSO's over a TSO product is acceptable? How could I, even if I understood all the tso testing and general electronics manufacturing business, make fact based assessments as to the reliability of any electronic equipment unless I had a lab and testing lab essentially?
I'm sure there is anecdotal evidence of the Dynon's reliability. And I understand we might want to behave in ways that mitigate against a single failure ruining my day. But in a pinch, what tells me to trust one instrument over another in a serious moment, especially when the error is not so great to be obvious? Skip
