Development Update – Bell 412 Project

Dear Cerasimmers,

We would like to share an update on the current development status of our Bell 412 project. Over the past few months, our team has been deeply immersed in studying and mastering the new flight dynamics of MSFS 2024. We have invested hundreds of hours analyzing how CFD (Computational Fluid Dynamics) particle interaction affects helicopter airframes; this research has been essential to successfully integrate the simulator’s new capabilities with our flight model.

Thanks to this extensive study and advanced technical collaboration, we have developed a 3-axis AFCS (Automatic Flight Control System) from the ground up. Rather than implementing generic solutions, we have programmed a core system based on the logic of the real-world Honeywell SPZ-7600. By utilizing C++ (WASM) programming, we are achieving native integration with the simulator’s physics engine, allowing us to deliver absolute stability and a complete suite of Flight Director modes. Currently, this development is in the pre-alpha phase.

Once the fine-tuning of this control core is complete, we will begin the flight dynamics calibration phase. Our goal is to replicate the exact behavior of the Bell 412EP, incorporating complex physical phenomena such as:

• Translational Lift: Precise modeling of aerodynamic translational lift.
• Vortex Ring State (VRS): Simulation of vortex ring state for preventive training.
• Torque-Pitch Coupling: Dynamic compensation of the inertias generated by rotor torque.

In parallel, our art team continues to refine the 3D model and integrate complex cockpit systems, ensuring that our visual fidelity matches the technical sophistication of our flight systems.

This project demands an extremely high level of engineering. We are working intensely to provide you with an experience that truly captures the complexity and rigor of operating a Bell 412. We appreciate your patience and continued support as we perfect every detail of this project.
