They have evolved into core digital infrastructure supporting the full industrial chain development of the low-altitude economy. From the dimensions of market scale, technological evolution, application scenarios, industrial value and existing challenges, this paper comprehensively analyzes the future development prospects of eVTOL flight simulators. It reveals their irreplaceable role in the whole chain of research and development, airworthiness certification, pilot training, operational support and public science popularization. It is predicted that eVTOL flight simulators will embrace a golden development period alongside the boom of the low-altitude economy, becoming a pivotal force driving the reform of Urban Air Mobility (UAM). 1. Industry Opportunity: Rise of Low-Altitude Economy Usher in an Outbreak Period for Simulators 1.1 Accelerated Commercialization of eVTOL Generates Rigid Market Demand As the core carrier of the low-altitude economy, eVTOL features zero emissions, low noise, vertical takeoff and landing, and high flexibility. It is regarded as a revolutionary solution to urban traffic congestion and the reconstruction of transportation patterns. Globally, the industry has entered the final stage of commercialization. By 2026, leading enterprises at home and abroad including Joby, Volocopter, EHang and Fengfei have completed multiple rounds of flight tests. Multiple aircraft models are in the critical phase of airworthiness certification by FAA, EASA and the Civil Aviation Administration of China. Large-scale commercial operation is expected to be realized between 2027 and 2030, with the global eVTOL fleet expanding from hundreds to thousands of units. The technical characteristics and operational scenarios of eVTOL are fundamentally different from those of traditional fixed-wing aircraft and helicopters. Adopting distributed electric propulsion systems, multi-rotor/tilt-rotor layouts, fly-by-wire flight control and battery energy management systems, eVTOL mainly operates in complex low-altitude airspace of 100–1000 meters above urban areas. It faces new challenges such as urban canyon wind shear, high-rise electromagnetic interference, high-density airspace coordination, and precise takeoff and landing at vertiports. Traditional aviation simulators cannot adapt to its unique dynamic characteristics, power system logic and scenario requirements. This has given birth to a brand-new market for eVTOL simulators, which has become an inevitable industry demand. 1.2 Market Scale: Steady Global Growth and Rapid Expansion in China According to forecasts by authoritative industrial institutions, the global eVTOL simulator market reached approximately 4–4.3 billion US dollars in 2025, with a Compound Annual Growth Rate (CAGR) of 6.7% from 2026 to 2035, exceeding 8 billion US dollars by 2035. The market structure shows clear segmentation: engineering research and development simulators account for 35%, serving model design, flight control iteration and system joint debugging; training-grade simulators occupy 40%, acting as the core carrier for large-scale pilot training; FAA/EASA certified full-motion simulators take up 20%, with a unit price as high as 20–50 million US dollars, forming the high-value core segment; public experience simulators account for 5%, tapping the blue ocean consumer market. The growth rate of China’s market far exceeds the global average. The market size reached about 320 million RMB in 2025, accounting for 25.6% of the global total. The CAGR will exceed 30% in the next five years. After 2030, the market will enter an exponential growth phase with the implementation of airworthiness certification and large-scale aircraft delivery. China has fully supported the low-altitude economy with favorable policies. The low-altitude economy has been incorporated into strategic emerging industries, and the opening of airspace below 1000 meters continues to advance. The Civil Aviation Administration of China is accelerating the formulation of eVTOL airworthiness standards, clearly taking simulator data as a core basis for airworthiness evaluation, creating policy dividends and market conditions for the development of the domestic simulator industry. 1.3 Core Driving Forces Consolidate the Foundation of Growth First, mandatory requirements for airworthiness certification. Global civil aviation regulators stipulate that eVTOL aircraft certification requires thousands of hours of virtual flight tests, covering full-scenario fault simulations such as power failure, battery thermal runaway, flight control malfunction and extreme weather. Simulators are essential tools for airworthiness verification, shortening the traditional certification cycle from 5–7 years to 3–4 years. Second, explosive demand for pilot training. The commercialization of eVTOL will create a shortage of hundreds of thousands of pilots. Real aircraft training features high cost, high risk and low efficiency, while simulator training costs only 5% of real flight training, reducing actual flight time by 80% and enabling 24/7 risk-free training, becoming the only way for large-scale talent cultivation. Third, irreplaceable advantages in technology and cost. The characteristics of eVTOL including electric propulsion, distributed rotor and urban low-altitude operation determine that real aircraft cannot completely replace simulators. Extreme faults, complex weather and high-density coordination scenarios are difficult to practice repeatedly on real aircraft, while simulators can restore real scenarios and reproduce them infinitely. Meanwhile, they greatly reduce carbon emissions from R&D and training, supporting the green transformation of aviation. Fourth, empowerment of the entire low-altitude economic chain. Beyond R&D and training, simulators extend to airspace planning, operational scheduling, emergency drills and public science popularization. They serve as a digital link connecting the whole industrial chain of “R&D-Manufacturing-Operation-Service”, delivering value throughout the entire industrial life cycle. 2.
