Avidyne Adds Bonanza to Autopilot Approvals

The FAA issued a supplemental type certificate (STC) to Avidyne covering installation of the company’s DFC90 autopilot in 25 Beechcraft Bonanza models. The STC requires interfacing with the Aspen Avionics EVD1000 Evolution Pro PFD. The DFC90 autopilot is a plug-and-play replacement of the S-Tec 55X autopilot and uses the 55X’s servos. The DFC90 can also replace S-Tec 30/50/60-2/65-series autopilots in the 25 Bonanza models covered by this STC.
