A2A Simulations has released their Accu-Sim Aerostar 600 for Microsoft Flight Simulator 2024 in Early Access. It's the company's first fully native aircraft for the new platform, taking full advantage of its features, performance enhancements, and visual capabilities.

It enters early access in a late beta stage, with most of its systems and features already in place, only requiring a bit of further polishing as they move toward the full release. 

The Aerostar 600 was designed and built by Ted Smith Aircraft Company in the late 1960s, with speed, sleekness, and power in mind. It was the fastest twin-piston general aviation aircraft during its heyday.

Powered by two Lycoming IO-540-K engines, each producing 290 horsepower, it can cruise at 408 km/h, with a service ceiling of 25,000ft and 1,500 nautical miles of range on a single tank.

Like their Comanche 250, it is built on their proprietary Accu-Sim 2.0 technology, bringing an advanced aerodynamic system that faithfully represents how the airplane's surfaces interact with the air, along with realistic simulation of wear and tear on the airframe and engine, an in-depth electrical simulation, and much more. The complete feature list follows below:

• Optimized Performance: Fully Native MSFS2024 model with all the LOD and performance features that comes with a native model. Fluid in-sim performance comparable to default MSFS2024 aircraft.

‍

• Accu-Sim 2.0 Aerodynamics: Physics-based external aerodynamics engine for realistic flight dynamics, validated against real-world Aerostar performance.

‍

• Per-Cylinder Engine Simulation: Complete physics-based model of twin Lycoming IO-540-G1B5 engines, simulating fuel injection, ignition, and wear.

‍

• Dynamic Ground Physics: True weight-on-wheels simulation, tire side-loading, and surface-specific responses (e.g., pavement, grass).

‍

• Sophisticated Vibration Physics: Realistic ground roll and engine vibration effects, unique to the Aerostar’s twin-engine configuration.

‍

• Authentic Fuel System: Simulates fuel lines, crossfeed, boost pumps, and contamination risks, with 174.5 gallons usable capacity.

‍

• Custom Oil System: Dynamic viscosity and contaminants that degrade oil, affecting engine performance.

‍

• Advanced Starter Simulation: Physically turns engines through compression cycles, with realistic starting challenges.

‍

• Physics-Driven Sound Environment: Over 1,000 dynamic sound effects, including engine rumble, hydraulic pumps, and cockpit interactions.

‍

• Detailed Modeling: High-fidelity external and internal textures with wear effects, dynamic registration decals, and animations.

‍

• Custom Avionics Stack: Collins Microline avionics with AMR-350 audio panel, VHF-251 COM radios, VIR-351 nav receivers, IND-450 DME, ADF-650 and TDR-950 transponder

‍

• GPS Integration: Supports MSFS default/Working Title GNS 430W/530W, freeware KLN-90B, PMS GTN 750, and TDS GTN 750Xi (if installed).

‍

• Century NSD-360A HSI: Custom needle-smoothing physics for realistic navigation.

‍

• Century IV Autopilot: Advanced two-axis autopilot simulation.

• Simulation of JPI EDM 790 and EDM 760 digital engine monitors, with authentic displays and leaning procedures. Both Rich of Peak and Lean of Peak modes are available.

‍

• Native MSFS2024 Pilot’s 2D/3D Tablet: Intuitive interface for fuel, payload, maintenance, and engine analysis, with environmental data display and more.

‍

• Interactive Walkaround: Inspect moving parts (e.g., control surfaces, gear) with failure and wear simulation.

‍

• Persistent Aircraft: Customizable wear and failure rates, adjustable via tablet, with persistence by livery.

‍

• Graphical Engine Analyzer: Detailed insight into engine operation, including cylinder pressures and temperatures.

‍

• Real-Time Load Manager: Dynamic weight and balance with graphical CG indicator.

It's available on their website for $49.99.
