Avidyne has received FAA STC approval for installation of the Avidyne DFC90 Digital Autopilot into Beech Bonanza-series aircraft when interfaced with Aspen’s Evolution 1000 Pro Primary Flight Display (PFD).
The approval covers the DFC90 autopilot as a plug-and-play retrofit of existing STEC55X systems in twenty-five models of the Bonanza series, all of which are on Aspen’s Approved Model List, including the 35-33, 35-A33, 35-B33, 35-C33, 35-C33A, E33, E33A, E33C, F33, F33A, F33C, G33, H35, J35, K35, M35, N35, P35, S35, V35, V35A, V35B, 36, A36 and A36TC.
The DFC90 uses the existing servos of the STEC55X autopilot that it replaces. STEC30/50/60-2/65 series autopilots may also be replaced by a DFC90 under this STC.
The Evolution Integration Kit for the DFC90 kit, similar to other Aspen upgrades, is an easy software upgrade to the Evolution Pro PFD. The kit for the DFC90 enables the PFD to provide precision attitude inputs to the autopilot from its reliable, solid state Air Data and Attitude Heading Reference Sensor (ADAHRS) as well as display mode annunciations and alerts right on the PFD. Additional capabilities include allowing pilots to perform Heading Select, Altitude Preselect, and Vertical Speed Select inputs to the DFC90 directly from the Evolution Pro PFD.
The combined safety enhancing features of the DFC90 and the Aspen glass panel, at this affordable price, is an unbeatable retrofit solution.
