About
China Simulation Sciences (CSS), founded in 2019 under Juneyao Group, delivers high-standard simulation solutions for global flight training. Guided by the philosophy “Autonomous Software. Open Data. Limitless Applications,” CSS advances aviation simulation with innovation and precision.
Holding dual certifications from EASA and CAAC for Level D full flight simulators — a distinction unmatched in China — CSS has deployed Airbus A320, Boeing B737, and COMAC C909 simulators with 100% in-house core technologies, delivering more than ten Level D FFSs. In 2025, the CSS-developed Airbus A320 Level D Full Flight Simulator was successfully delivered to Paris, marking a historic breakthrough as the first export of China's high-end aviation simulation equipment.
Beyond civil aviation, CSS is expanding into the low-altitude economy, developing simulation systems for UAVs and eVTOLs to forge a "dual-engine" strategic framework that integrates high-end commercial flight simulators with intelligent low-altitude simulation.
Pursuing the strategy of “Globalized Products with Localized Services,” CSS has established a service network spanning international markets across Southeast Asia and Europe. Committed to independent innovation and safety-centric training, CSS continues to empower global aviation talent development and the low-altitude ecosystem, steadily advancing toward the forefront of global aviation simulation technology.
