This has been a recurring subject that I drop on the group from time to time.
If you search barnstormers, there is an ad for.. ERCOUPE 415 C / LSA / S #1565 It shows and lists a Dynon D-100 installation with a mention that it has "all primary flight instruments". I assume this was approved because it is considered a supplimental instrument rather than a primary. Other than a Garmin 696 mounted on a panel, has anyone else seem any EFIS-like Ercoupes? I have seen the threads on TSO/NON-TSO gear. Assuming this passed all the hurdles, are there any other good examples of "FAA blessed" or "approved, Non-TSO" efis gear that has been put to service in a coupe?
