Asobo Studio & Working Title’s AAU2 Beta Released for MSFS

Asobo Studio and Working Title’s Aircraft & Avionics Update 2 (AAU2) for Microsoft Flight Simulator is now available in beta.

This new update fixes issues with the Garmin (G3000, G5000, GNS430W, and GNS530W), and brings a major avionics overhaul for the Boeing 747-8i included in the Standard Edition and the Boeing 787-10 Dreamliner included in the Premium Deluxe Edition.

Asobo Studio and Working Title’s AAU2 was announced earlier this month and promised a significant reduction in INOP buttons and switches including adding more realism and accuracy to both Boeing models to make them feel more premium. The extensive list of changes includes updates and features such as a complete screen visual overhaul to avionics fonts, look, integration and feel, integrated checklists on the MFD, performance-based VNAV with idle descent capabilities, RNP/ANP indications, updated flight models, upgraded GPS and IRS navigation systems, autopilot overhaul with Autoland, Flare, and Rollout modes, a fully featured auto throttle system with correct AT modes, and more. The Boeing 787-10 has also had a sound overhaul more accurately representing the Rolls-Royce Trent 1000 engines.

Some fixes and updates have also made their way to the Cessna Citation Longitude and the Daher TBM 930, although despite these changes there are still known limitations acknowledged by the developers such as the Electrical Control Systems (Air Conditioning), the 787’s EFB performance calculations and the 747’s electrical transfer busses are not yet available, these are being worked on however. Other features such as Navigraph SimBrief integration is not supported and will still rely on the community mods due to legal restrictions.
