“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 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.”

Purchase your copy of the Accu-Sim Comanche 250 simulation for MSFS on the A2A Simulations store;

• Real time load manager with dynamic weight and balance indicator.
• Electrical system analyzer and circuit breaker functionality.
• Two naturally animated rear seat passengers and support for native MSFS avatars in the front seats.
• Fluid in-sim performance comparable with default aircraft of the same class.

The Comanche 250 with our new Accu-Sim technology is finally the hands of our beta testers. Though beta testing has been underway for a bit, we’re still busy working around the clock adding some exciting new features, so the beta process will still take some time to complete.

I’ve been trying to think about what to say but the first post from one of our lead beta testers summed it up perfectly:

We’re really looking forward to sharing more complete information on this new Accu-Sim functionality shortly before release.

If you have any questions you can ask and/or chat with us and the A2A Community here on the forums

We’re really excited to show you some screenshots of the current Accu-Sim Comanche 250 cockpit, taken straight from MSFS without any processing. We are working around the clock to make this the very best airplane we’ve ever made in every aspect, physical, visual, and aural. While we’re not in Beta yet, progress is moving quicker every day.

The Accu-sim B-17 simulation for the Lockheed Martin Prepar3d platform takes to the skies with its release today!

To celebrate the release we also have a great 40% off the whole A2A store for this week, a great time to update your A2A collection.

Happy flying in the virtual blue skies!

2020 is shaping up to be a remarkable year for flight simmers with the upcoming relaunch of the iconic Microsoft Flight Simulator and the recent release of Lockheed Martin’s Prepar3D v5. We haven’t been able to share much information about our future projects until now, but the team at A2A Simulations are excited to be building the Aerostar 600 twin for both MSFS and P3D v4/v5 using the latest generation of Accu-Sim.

For those new to A2A Simulations, Accu-Sim is a technology that allows us to build lifelike, persistent aircraft with all their underlying systems and characteristics. The first iteration of Accu-Sim was launched in 2008 in the form of a classic 4-engine piston airliner, the Boeing 377 Stratocruiser.

As Accu-Sim has evolved and grown in reputation, A2A Simulations has been given the chance to simulate training aircraft for the US military. This is both a tremendous responsibility and a great opportunity to develop our core technology based on crucial hands-on experience, so that it can simulate other powerplants, systems and even rotary-wing aircraft.

The Future

We still hope to be able to bring some of these military products or their offshoots to public release in the future. However, our current focus is very much on releasing our first product for the 2020 iteration of Microsoft Flight Simulator.

Many of our customers have asked if we plan to “port” our existing Accu-Sim fleet into the new sim. Instead, we’ve spent the past year developing a new version of Accu-Sim to build and test virtual aircraft. Future releases won’t just be ports of existing products, but instead they’ll take full advantage of the features and potential of the new platform to bring an unprecedented level of fidelity and quality.

The Accu-Sim Aerostar is also different in that it’s being designed largely for the purpose of training. A2A owner and developer Scott Gentile owns and operates Aerostar N122PC and wants his airplane “Accu-Simmed” for the specific purpose of becoming the safest pilot he can be.

Double blind tests have been conducted between pilots trained exclusively on the real aircraft compared to pilots trained mostly using Accu-Sim and the difference between these groups is indistinguishable. This is well beyond what the existing simulators we’ve tested are capable of. This is why we accepted the call from the US military. The need was just so obvious,

Scott Gentile of A2A Simulations Inc.

Anyone who wishes to learn how to operate a real Aerostar 600 will be able to on a level of detail never before possible.

A2A has always believed that when things are real, it’s easier. Just flying an Accu-Sim aircraft for fun turns you into a better pilot because you are experiencing many things indistinguishable from reality. Experiencing real physics and sound is so fun you don’t even realize you are learning,

Lewis Bloomfield of A2A Simulations Inc.

Because Microsoft Flight Simulator and the Accu-Sim v4 tools are still in development, it’s too early for us to know with any certainty how long it will take to complete this first project.

However once the Aerostar 600 is released, it will represent the first airplane created with the new Accu-Sim v4 toolset, so successive aircraft developed will take less time to reach the same level of quality.

In the meantime, congratulations to Microsoft and Asobo for creating a wonderful new flight simulation to propel this industry well into the future.
