Del Fadden has a nice piece in the “stories” section of this website on his experience with the ARNAV engine monitoring system. Since he and ARNAV are in the Seattle area they were working with the local FSDO out there to get an STC on the system. Other folks have noted that certain shops will not install the unit at all until “FAA approval”
Del has not left his email address on the article. Does anyone know of the status of their work to get the STC in Seattle? It seemed they were hoping August would be the month but that was a few months ago.
