Approves Advanced Features Of Digital Units In cirrus Aircraft
Avidyne Corporation, a leading provider of integrated avionics and safety systems for general aviation aircraft, today announced that they have received Agência Nacional De Aviação Civil –Brasil (ANAC) validation for their DFC90 Release 2 software upgrade which adds full-time Envelope Alerting (EA) capability and also allows the option of wiring the aircraft for dynamic Envelope Protection (EP) with Flap Sensing for Cirrus SR20 and SR22 aircraft in Brazil.
The ANAC approval also includes validation of software v9.2.4, which adds flap overspeed sensing capability for Cirrus aircraft with the Entegra Release 9 and DFC100 package.
“These new features, including Full-time Envelope Alerting and flap-sensing dynamic Envelope Protection, provide additional safety enhancements for our DFC-series autopilot customers, and we are pleased to be able to extend these capabilities to our Brazilian customer base,” said Patrick Herguth, Avidyne’s Chief Operating Officer.
The DFC90 and DFC100 are digital autopilot systems that are designed as slide-in replacements for the S-TEC55X autopilot. They add the precision and reliability of an attitude-based flight control system, by taking advantage of the single or dual ADAHRS in the Entegra and Release 9 systems. Both autopilots provide the safety enhancements of the ‘Straight & Level’ mode, providing one-button unusual attitude recovery, Flight Envelope Protection (EP) and full-time Envelope Alerting (EA).
EP virtually eliminates autopilot-induced stalls (underspeed) and overspeeds, while EA protects against flight envelope exceedences by providing visual and aural warnings to the pilot, even when the autopilot is not engaged. In addition, the DFC90 and DFC100 add Indicated Airspeed Hold (IAS Hold) capability, which is a preferred method for climbing and descending in these higher-performing aircraft.
