Dynonizing a Bonanza 1975 V35B N315AB D-9740

Robert Colabianchi, Fountain Hills, Arizona, by Kevin Knight

Phoenix pilot Bob Colabianchi had a problem. After getting his Private certificate in 2015 and buying a 1975 V35B, N315AB one year later, he installed an Avidyne IFD 540 and Aspen Pro, and connected them to the existing Century IV autopilot. Unfortunately, they never worked well together. Since he’s averaging 220 VFR hours annually and was about to get his IFR ticket, he wanted to be confident when flying his wife and two sons around the country.
