AVIDYNE DFC90 DIGITAL AUTOPILOT

Avidyne DFC90 Digital Autopilot. Avidyne’s DFC90 Attitude-Based Digital Autopilot enhances precision of flight and has a safety-enhancing EP capability. DFC90 utilizes either an Entegra EXP5000 or Aspen EFD1000 Pro PFD as the attitude source, and uses vertical and lateral modes of operation of a turbine-class autopilot system. This autopilot includes a Flight Director, Altitude Hold, Airspeed Hold, Vertical Speed Hold, Heading, and Navigation (NAV, APPR, LOC/GS, GPSS). Avidyne’s Envelope Protection prevents autopilot-induced stalls and overspeeds, while providing visual/aural warnings to the pilot. Lift and speed margins are calculated when the aircraft is nearing its normal flight parameters, even if autopilot is off. A Straight & Level Button recovers the aircraft from unusual attitudes, and overrides all autopilot modes and levels the aircraft in both pitch and roll.
