DFC90

Description

Avidyne’s DFC90 Attitude-Based Digital Autopilot enhances precision of flight and improves safety for your aircraft.

Avidyne’s DFC90 Attitude-Based Digital Autopilot enhances precision of flight and improves safety for your Entegra-equipped Cirrus.

The DFC90 adds the precision of an attitude-based flight control system and Avidyne’s innovative, safety-enhancing Envelope Protection (EP) capability and Envelope Alerting (EA).

The DFC90 has all the standard vertical and lateral modes of operation of a turbine-class autopilot system, including; Enhanced Flight Director (FD), Altitude Hold (ALT), Airspeed Hold (IAS), Vertical Speed Hold (VS), Heading (HDG), and Navigation (NAV, APPR, LOC/GS, GPSS)

Customers upgrading from the S-TEC 55X servos will notice several major performance and feature improvements such as:

ATTITUDE-BASED

Greatly improved stability due to the use of attitude data to control the autopilot inner control loops. This is particularly evident and important when tracking an ILS to minimums in windy conditions.

EP® – AVIDYNE’S ENVELOPE PROTECTION

Prevents autopilot-induced stalls and overspeeds, which have previously been a major contributing factor in GA accidents, when the autopilot is engaged.  Avidyne’s EP also provides visual and aural warnings to the pilot.

EA® – AVIDYNE’S ENVELOPE ALERTING

Available lift and speed margins are calculated constantly in the background, providing visual and aural warnings to the pilot when the aircraft is nearing its normal flight parameters, even when the autopilot is off.

“STRAIGHT & LEVEL” BUTTON

Recovers the aircraft from unusual attitudes. Overrides all autopilot modes and levels the aircraft in both pitch and roll from a wide range of capture attitudes for an added measure of safety.  S&L button provides added peace of mind—especially for the non-pilot in the right seat.

INDICATED AIRSPEED HOLD (IAS)

New vertical mode includes a dedicated Airspeed knob and a new airspeed bug on the PFD. Provides constant speed flight level changes.

ENHANCED FLIGHT DIRECTOR

Capability of the DFC90 is vastly improved and greatly improves the ability to hand-fly approaches.

SYNCHRONIZED HEADING BUG

With the DFC90, turns are commanded in correlation with the spin of the heading knob. In other words, you can make the autopilot do a right-hand 270 degree turn if you spin the heading knob right 270 deg.

There are many other improvements, such as a dedicated Vertical Speed knob, pitch hold mode, wide autopilot engagement, additional annunciations in PFD 8.0, a dedicated GPSS button, automatic Back Course Approach selection, multiple color annunciations to indicate armed and active states, intercept mode annunciations, and Avidyne’s hallmark ease of use.

PLUG & PLAY

DFC90 is plug & play with the STEC55X, and STEC30/50/60-2/65 series autopilots may also be replaced by a DFC90 under these STCs.
