When there is a human-in-the-loop component, physics-based modeling is a necessity because the dynamics and fidelity of controlled entities are sometimes as crucial as the visual realism of the simulator.  Unrealistic movements or reactions of controlled entities can result in ‘negative training’, causing the learning of counter-productive behaviors.  

Model dynamics and fidelity are especially critical in flight simulators, where pilot training is almost exclusively executed on a simulator and where mistakes in the real aircraft can lead to expensive mishaps, injury, or death.  

Examples of physics-based modeling include:

• vehicle weight and balance,
• hydraulics,
• engines,
• controls,
• undercarriage forces,
• aerodynamics and surfaces,
• suspension,
• sensors.
  

Presagis products allow you to create the realistic visuals and motion that your simulation requires and give you the flexibility to adapt your projects to future requirements.  STAGE Flightsim and STAGE Helisim provide a development environment to efficiently create advanced flight simulation models for fixed or rotary wing aircraft.  These solutions allow users to concentrate on defining the exact behavior of the aircraft that they wish to simulate by providing the complete framework to establish the necessary aerodynamic and other physical models. STAGE Flightsim and Helisim thus effectively translate the user's models into dynamic behavior. Real-time simulation of any aircraft can be achieved through the creation of high-fidelity models with full six degrees of freedom (DOF).

S-Mission provides a comprehensive range of entity land and maritime behaviors, as well as the most sophisticated air behaviors on the market.  S-Mission also delivers many physics-based effects such as propagation, attenuation, and Doppler.
