Accu-Sim Aerostar 600
After years of refining Accu-Sim technology, A2A Simulations proudly presents the
Aerostar 600, powered by our all-new Accu-Sim 2. 0. Built from the ground up, this
technology redefines flight simulation with a physics-based approach to
aerodynamics, engine modeling, and aircraft systems. The Aerostar 600, a high
performance twin-engine aircraft, was chosen as our flagship for Accu-Sim 2. 0 due to its

our advancements.
Development involved extensive research and testing, leveraging real-world Aerostar
data to ensure authenticity. From the Lycoming IO-540-G1B5 engines to the dynamic
hydraulic and electrical systems, every aspect is simulated with unprecedented fidelity.
Our new aerodynamics engine captures the Aerostar’s responsive flight characteristics,
while the pilot’s tablet offers intuitive control over loading, maintenance, and system
monitoring.

Accu-Sim Comanche
“Well, I can finally show you why we have been so quiet for three years. We’ve been steadily working on an all new way to create airplanes called “Accu-Sim 2. 0”. Our long time customers know Accu-Sim well as it’s been powering our airplanes for over a decade. During that time we’ve learned a lot. While this new technology carries the same Accu-Sim name, this latest version was built brand new from a clean slate.

We’ve been steadily working on an all new way to create airplanes called “Accu-Sim 2. 0”. Our long time customers know Accu-Sim well as it’s been powering our airplanes for over a decade. During that time we’ve learned a lot. While this new technology carries the same Accu-Sim name, this latest version was built brand new from a clean slate.
We are so very happy to say, we have succeeded in everything we set out to do. We didn’t cut any corners and this brand new Accu-Sim technology represents everything we dreamed of. Perhaps the biggest dream and challenge was to create a new aerodynamics system that allowed us to model how an airplane flies through the air. It’s the kind of simulation we knew was possible but wasn’t yet realized. Nobody has done anything like this before. This represents a quantum leap for us, and it’s the beginning of a whole new way of developing airplanes for flight simulation.
I decided early on the first airplane we had to simulate with Accu-Sim 2. 0 would be the Comanche 250, as this is an airplane I have owned and operated for over 10 years. It feels like a nice pair of shoes that are perfectly broken in yet still look good. During development I was continuously asking questions without acceptable answers, and our Comanche gave us every answer we asked. Owning the airplane offers tremendous advantages as you don’t need to ask permission or explain why you need to perform some odd sounding test. None of our testing was dangerous but much of it involved things nobody, including me had ever done before. There is a reason I have owned and operated a Comanche 250, N6229P for over a decade, and now through Accu-Sim 2. 0, you can better understand why. ”

Accu-Sim Legacy RG550 New
Our Legacy In Your Hands
Some aircraft are special the moment you see them. The Legacy RG550 was one of those for us. Fast, sleek and unmistakably individual, it brings together high performance and the hands-on character of a homebuilt aircraft.
Powered by a big engine, the RG550 delivers strong acceleration, climbs of more than 2,000 feet per minute and cruise speeds of up to 280 miles per hour. It’s quick and responsive in the air, yet composed at the stall and approachable on landing.... Our Legacy In Your Hands
Some aircraft are special the moment you see them. The Legacy RG550 was one of those for us. Fast, sleek and unmistakably individual, it brings together high performance and the hands-on character of a homebuilt aircraft.
Powered by a big engine, the RG550 delivers strong acceleration, climbs of more than 2,000 feet per minute and cruise speeds of up to 280 miles per hour. It’s quick and responsive in the air, yet composed at the stall and approachable on landing. The roomy cockpit and one-piece lifting canopy give you an open view as you explore the skies.
Experience the Legacy with Accu-Sim
Accu-Sim is A2A’s own simulation engine, bringing the Legacy RG550’s custom flight model, engine and aircraft systems together in one cohesive experience. The result is an aircraft that responds to your inputs and feels alive in the air, from the first moments of acceleration on the runway to the subtle changes you’ll notice as you fly.
Each Legacy has its own character. Individual avionics installations, careful engine tuning and wear over time help make every flight feel personal. Choose from cockpit options and avionics configurations, including A2A’s custom avionics and support for classic third-party GPS units.
Take the Legacy out for a relaxed tour or put its performance to work. This is a detailed, immersive aircraft add-on for Microsoft Flight Simulator 2024, created for pilots who want more than a model to look at.
A Microsoft Flight Simulator 2020 version will be added to this package free of charge after release, following the same approach as the Accu-Sim Aerostar.
Created through thousands of hours of work, the Accu-Sim Legacy RG550 brings this remarkable aircraft to your flight simulator.
Welcome to the Legacy experience.
