Avidyne DFC90/DFC100

Avidyne DFC90/DFC100

If your Cirrus is already Entegra-equipped you should consider upgrading to Avidyne’s DFC90 or DFC100 Attitude-Based Digital Autopilot for an enhanced precision of flight and improved safety for you, your passengers and your aircraft.

The DFC90 and DFC100 both add the precision of attitude-based flight control systems, along with Avidyne’s innovative and safety-enhancing Envelope Protection capability. The DFC90 is used with the Entegra one PFD’s and the DFC100 with the new Release 9 IFD’s

Description

If your Cirrus is already Entegra-equipped you should consider upgrading to Avidyne’s DFC90 or DFC100 Attitude-Based Digital Autopilot for an enhanced precision of flight and improved safety for you, your passengers and your aircraft.

The DFC90 and DFC100 both add the precision of attitude-based flight control systems, along with Avidyne’s innovative and safety-enhancing Envelope Protection capability. The DFC90 is used with the Entegra one PFD’s and the DFC100 with the new Release 9 IFD’s

These two systems from Avidyne feature all the standard vertical and lateral modes of operation of a standard turbine-class autopilot system, including Flight Director (FD), Altitude Hold (ALT), Airspeed Hold (IAS), Vertical Speed Hold (VS), Heading (HDG), and Navigation (NAV, APPR, LOC/GS, GPSS).

If you are upgrading your system from the STEC 55X you will notice a range of major performance and feature improvements such as the following:

Attitude-Based – The use of attitude data as a means to control the inner control loops of the autopilot will produce noticeably improved stability. This is all the more noticeable and important in windy conditions when tracking an ILS to minimums.

Flight Envelope Protection – Autopilot-induced overspeeds have been a major contributing factor in general aviation accidents in the past, and are prevented with both the DFC90 and the DFC100 systems in place. This includes having the autopilot avoid exceeding the flight envelope, whilst providing both visual and audible warnings to the pilot.

“Straight & Level” Button – Recover your aircraft from unusual attitudes at the touch of a button. This feature overrides every other autopilot mode, levelling an aircraft in both pitch and roll from a range of different capture attitudes adding an added measure of safety. The Straight & Level button certainly provides extra peace of mind in the case of pilot disorientation or prior to activating the Cirrus’ parachute.

Indicated Airspeed Hold (IAS) – An all new vertical mode comes complete with a dedicated Airspeed knob, as well as a new airspeed bug on the PFD. This will provide you with constant speed flight level changes.

Enhanced Fight Director – The capability of the enhanced flight director within the DFC90 and the DFC100 is vastly improved and dramatically helps with the ability to hand-fly approaches.

Synchronized Heading Bug – Within the DFC90 and DFC100, turns are commanded in conjunction with the spin of the heading knob. Essentially this means that you can make the autopilot perform a right-hand 270 degree turn by spinning the heading knob to the right by 270 deg.

There are too many other improvements to cover in detail here, 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 colour annunciations to indicate armed and active states, intercept mode annunciations, all combined with Avidyne’s consistent ease of use.

Flight Envelope Protection

No matter what mode is in operation, the available lift and speed margin will constantly be calculated in the background for flight envelope protection. If your aircraft approaches a stall situation, the autopilot will act unobtrusively to reduce the maximum bank and Vertical Speed gradually by just enough to keep the wing flying, whilst informing the condition to the pilot. The result of this is that departure from controlled flight is prevented with the least obtrusive impact on achieving mission level objectives such as navigation, climb or approach. Overspeed is handled in a similar fashion, with anticipation and minimal but highly effective inputs. When in a Flight Director Mode these actions will appear instead as guidance cues, with any corrections blended into the “V-bar” commands.
