This month’s panel for planning is for a mid-1980s Cessna 172 equipped with a Garmin GNS 530W and GNS 430W, S-TEC single-axis autopilot and original round-gauge flight instruments. Its owner is ready to make the plunge into an all-glass, all-electric avionics suite and is sold on the Dynon SkyView HDX Certified suite because her experimental kit aircraft (she didn’t build it, but purchased it secondhand) has older Dynon gear.
After getting a thorough demo at Sun ‘n Fun, the proposed package includes removing all of the existing flight instruments, engine instruments (including fuel gauges), the S-TEC autopilot, Garmin GMA 340 autopilot, both Garmin navigators and the Mode S transponder. Since the aircraft lived overseas, it also needs a U.S. mandate-compliant ADS-B Out system, plus ADS-B In for receiving traffic and weather.
