A long journey is coming to an end - my Bonanza N70TB is back home in the hangar after ten months of upgrades and development/certification work. Let me give you a tour of the new setup, which is centered around the Aspen Evolution MAX flight displays and Garmin's GFC600 digital autopilot. The system also contains two Garmin GTN 750 Xi GPS/NAV/COM units, a GI 275 backup instrument, remote-mounted Garmin audio panel, transponder and active traffic system. For engine monitoring, I kept the JPI EDM 930 from my old setup.

The installation was done by Karl Gardner and his team at Gardner Lowe Aviation Services in Peachtree City, GA (Falcon Field). Garmin and Aspen have worked together on a digital interface between the Aspen PFD and the Garmin autopilot to enable features such as altitude preselect; these features are not yet enabled at the time this video was made because the FAA is still reviewing the new software version. Once it's approved, I'll get those features added to the Bonanza as well.
