China Simulation Sciences (CSS, 上海华模科技有限公司), 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 globally.

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. With Shanghai serving as its Asia-Pacific hub and Athens as its Europe hub, the company has built a dual-hub global after-sales and supply chain system to provide worldwide clients with efficient and precise technical support. 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.
