“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.”
