During the FSExpo 2025 weekend, Aerosoft made a significant announcement about bringing the Airbus A340-600 to Microsoft Flight Simulator. The revelation took place on the FSElite stage. In a new collaboration, Aerosoft has partnered with ToLiss, a highly respected developer known for creating detailed Airbus aircraft for the X-Plane platform. This partnership represents ToLiss’s first venture into the Microsoft Flight Simulator ecosystem.
According to official statements, the A340-600 is being developed natively for Microsoft Flight Simulator rather than being ported from ToLiss’s X-Plane lineup. The aircraft is being built from the ground up to fully utilize the simulator’s modern technologies, including advanced rendering systems and native flight dynamics. The development responsibilities have been clearly divided between the two companies. Aerosoft is handling all visual aspects, including 3D modeling and artwork, while ToLiss is responsible for the systems simulation, flight model, avionics, and overall logic. This division leverages ToLiss’s extensive expertise in creating realistic Airbus systems.
During the presentation, a feature video showcased an impressive engine fire scenario after takeoff. The demonstration highlighted accurate ECAM memos appearing after fire detection, which the user must follow to successfully manage the emergency. The video displayed proper procedures including retarding the affected engine’s thrust lever, turning off the master switch, activating fire suppression systems, and handling resulting abnormal bleed conditions. Key features of the upcoming A340-600 include:
- A fully custom fly-by-wire system
- Accurate FMGS and MCDU built specifically for the simulator
- Detailed failure management systems
- Comprehensive weight and balance configuration tools
- Aircraft state saving capability for pausing and resuming long-haul flights
While no specific release date has been confirmed, development is reportedly well underway, with the aircraft expected to launch before 2026. Initially, it will release for Microsoft Flight Simulator 2020, followed by an optimized version for MSFS 2024. Additionally, Aerosoft has confirmed plans to bring the A340-600 to Xbox, potentially making it the first high-end airliner for console users.
ToLiss leads systems development for A340-600
The Canadian firm ToLiss brings exceptional technical expertise to the A340-600 project, serving as the cornerstone of systems development for this highly anticipated Microsoft Flight Simulator addition. Renowned for creating some of the most authentic Airbus simulations available, ToLiss has established itself as a leader in flight simulation technology, particularly for its acclaimed X-Plane offerings.
ToLiss’s involvement extends far beyond basic system implementation. The company is handling all critical aspects of the aircraft’s digital brain, including systems simulation, flight model, avionics, and the comprehensive operational logic that defines how the aircraft behaves. One standout feature is the fully custom Flight Management Guidance System (FMGS), complete with independent Multipurpose Control Display Units (MCDUs). This system incorporates comprehensive VNAV guidance, go-around procedures, and alternate routing support — capabilities essential for realistic long-haul operations.
Despite this partnership, ToLiss confirmed they remain dedicated to X-Plane development, with ongoing projects planned for the next two years. Nevertheless, the team expressed hope that this A340-600 might be the first of many aircraft they develop for Microsoft Flight Simulator, potentially signaling a broader expansion into this platform.
Though scheduled for release before 2026, the wait appears worthwhile given the demonstrated attention to detail. ToLiss’s first venture into Microsoft Flight Simulator while maintaining their X-Plane development shows promising signs for the future of flight simulation across platforms.
