DFC90/DFC100 FAQ

• Adds support for the Entegra PFD equipped PA46 Matrix and Mirage aircraft;
• Added support to take flap position input to increase the accuracy of Envelope Protection alerts and behaviors (flap position wiring is optional but highly recommended);
• Added full-time Envelope Alerting.  This feature provides underspeed, overspeed, excessive bank, and flap overspeed alerting in Flight Director mode and when the autopilot is in standby (AP Ready);
• Changed system behavior such that if an AHRS-Turn Coordinator Miscompare is observed in-flight, the autopilot will no longer disconnect.  The aural and text alerting remain but the autopilot stays connected;
• Replaced the computer synthesized voice alerts with an actual human recording (her name is Charlotte);
• Added support for the aftermarket roll servo modification in Cirrus aircraft;
• Added an alert to notify the pilot if the autopilot has detected that the roll axis servo has reached its maximum limit (“SERVO LIMIT”);
• Added an alert to notify the pilot if the flaps are being oversped per POH airspeed limits.  This comes in the form of an aural alert (“Caution, Flap Overspeed”).  This feature requires the optional flap wiring modification;
• Added an alert to notify the pilot if the POH bank angle limit has been exceeded.  This comes in the form of an aural alert (“Caution, Excessive Bank”) and a text alert (“BANK LIMIT”);
• Provides suppression of Underspeed alerting while on short final, in the flare, and during landing rollout.  This requires the optional flap wiring modification;
• Removed the engagement limits of the DFC90 such that it can be engaged at any aircraft state.  The maximum demonstrated engagement values are listed in the pilot guide;
• Capped the upper end of the IAS bug to match the autopilot limitation speed (e.g. 185 KIAS in the Cirrus aircraft);
• Changed the system behavior when on an ILS or WAAS glideslope and the glide slope data is subsequently lost.  Now the system will revert to ALT Hold mode after approximately 5 seconds of no glide slope signal;
• Added support for Control Wheel Steering (CWS).  This is not available in all aircraft.

New features in the DFC100 Release 2 include:

• Adds support for the Entegra PFD equipped PA46 Matrix and Mirage aircraft;
• Changed system behavior such that in single AHRS equipped aircraft,  if an AHRS-Turn Coordinator Miscompare is observed in-flight, the autopilot will no longer disconnect.  The aural and text alerting remain but the autopilot stays connected;
• Added support for Control Wheel Steering (CWS) [Not available in all aircraft];
• Added support for Takeoff/Go Around (TOGA) [Not available in all aircraft];
• Added support for Flight Into Known Icing (FIKI) [Not available in all aircraft];
• Added an alert to notify the pilot if the flaps are being oversped per POH airspeed limits.  This comes in the form of an aural alert (“Caution, Flap Overspeed”). [requires the optional flap wiring modification];
• Provided suppression of Underspeed alerting while on short final, in the flare, and during landing rollout. [requires the optional flap wiring modification];
• Moves the autopilot disconnect tone off of the SD card so that it is still capable of being heard in the event of a MSR FAIL condition.;
• Changed the system behavior when on an ILS or WAAS glideslope and the glide slope data is subsequently lost.  Now the system will revert to ALT Hold mode after approximately 5 seconds of no glide slope signal.
