Avidyne Entegra is an integrated aircraft instrumentation system, produced by Avidyne Corporation, consisting of a primary flight display (PFD), and multi-function display (MFD). Cirrus became the first customer of the Entegra system and began offering it on the SR20 and SR22 aircraft in 2003 as the first integrated flight deck for light general aviation (GA). The original Entegra system, which is currently at Release 9 software, was designed to use third-party components such as a GPS from Garmin and an autopilot system from S-TEC Corporation.
