As the global commercial electric vertical takeoff and landing (eVTOL) and Urban Air Mobility (UAM) industries move forward into pilot validation and earlystage commercial exploration, manned eVTOL will mainly operate within highdensity urban lowaltitude airspace. Featuring distributed propulsion, vertical takeoff & landing, lowspeed nearearth navigation and urban obstacle avoidance, eVTOL imposes specialized and higher requirements on pilots’ situational awareness, emergency faulthandling and lowaltitudeenvironment adaptability. Conventional aircraft training devices cannot fully accommodate complex UAM operating conditions, generating growing industry demand for dedicated simulationtraining platforms. Leveraging selfdeveloped highfidelity simulation core engines, China Simulation Sciences (CSS) delivers endtoend pilot simulationtraining solutions for commercial manned eVTOL. Drawing on pilottraining practices from leading global eVTOL OEMs including Joby Aviation and Archer Aviation, CSS builds multiconfiguration, multiscenariooriented training architectures.
Operating Context of Commercial eVTOL & Core Pain Points in Pilot Training
Manned eVTOL is projected to serve shorthaul urban air commuting and intercity lowaltitude transport services. Its operating airspace is densely builtup with complex electromagnetic environments, subject to disturbances from gusts, building wake turbulence and bird activities. Its distributed electricpropulsion architecture yields failure modes and control feedback characteristics substantially different from conventional helicopters.
Current pilottraining workflows face three major challenges: realaircraft flight tests incur prohibitive costs for largescale training under extreme conditions and multiple superimposed faults; standardized simulationtraining hardware remains scarce, creating inconsistent training syllabi across jurisdictions; global UAM airworthiness and pilotqualification rules keep evolving, demanding training platforms with continuous adaptive iteration capabilities.
- Difficulty replicating nearground complex airflow and urbanobstacle scenarios on real aircraft Buildinginduced airflow, urban gusts and lowaltitude turbulence are highly stochastic and cannot be reliably reproduced by real aircraft. Simulation platforms enable safe, repeatable reproduction of diverse nearground aerodynamic disturbances to help pilots cultivate control habits suited for urban lowaltitude environments.
- High safety risks for training on multiunit distributedpropulsion failures Failure of one or multiple propulsion units represents a core training subject for multirotor eVTOL. Conducting such drills aboard real aircraft carries significant safety hazards. Simulation systems allow flexible configuration of propulsionunit failures at arbitrary positions and progressive powerdecay scenarios, covering major failurecombination profiles.
- Fragmented global UAM airworthiness regulations call for flexiblyextensible training frameworks EASA, FAA and national civilaviation authorities have successively released regulatory frameworks governing UAM operations and pilot certification, resulting in divergent trainingimplementation standards across regions.

FAQ
Q1: Can eVTOL simulators directly reuse helicopter simulator software stacks? A1: Direct reuse is not feasible. eVTOL exhibits distinct distributedelectricpropulsion dynamics, verticaltakeoffandlanding transition modes and urban lowaltitude airflow profiles compared with traditional helicopters. Dedicated dynamic models and environmentalsimulation modules are mandatory.
Q2: Can one single simulation platform support multiple eVTOL configurations? A2: Yes. Adopting modular architecture, the platform switches aircraft types by loading corresponding dynamicmodel datasets and swapping cockpit hardware, lowering capital expenditure for multivariant training programs.
Q3: Are official airworthiness qualification standards available for eVTOL simulation devices at present? A3: Global qualification specifications for UAM simulation hardware are still under development. CSS product architecture is prealigned with prereleased UAMFSTD draft documents published by EASA and FAA, laying technical groundwork for future official certification.
