Unfortunately no identity is carried or so far known for this demonstrator Y-5BG, a TPE-331 turboprop conversion of the Chinese-built version of the venerable An-2. Other improvements include adjustable slotted wings and a modified upper wing leading edge to reduce airflow stall and further enhance low-speed performance. The cockpit has also undergone a major update, including an IFR-standard Garmin Integrated Avionics System.
