"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."

Version 1.5.0:

  • Fixed airplane creeping post SU15 when engine is run up with brakes or chocks applied
  • Fixed a bug preventing airplane from moving away from parking spot in some locations when outside air temperature is well below freezing
  • Improved synchronization between navigation light switching and relay click sound when using panel light rheostat
  • Fixed air pressure display error in altimeter Kollsman window when set to use imperial units (inHg)
  • Improved battery performance slightly at very cold temperatures allowing for better chance of engine start
  • Extended the lifespan of the oil pump and oil lines
  • Slightly reduced the effectiveness of the fresh air vents
  • Improved the display logic for centre of gravity in tablet
  • Added additional telemetry variables for force-feedback hardware
  • Omitted WT GNS initialization sequence when aircraft is loaded with avionics power already on
  • Added update history for Marketplace

Version 1.4.7:

  • Added support for Xbox marketplace platform in sim
  • Fixed overstress crash which would occur if view was switched to outside camera following an apron start with cockpit persistence switched off
  • Improved engine physics so very high temperature can cause more rapid cylinder wall deterioration
  • Improved integrity of cabin against air leaks to allow more efficient heating
  • Fixed cabin vent bug which caused vents to not exchange air properly
  • Fixed issue which caused vents to pick up too much ambient wind on the ground
  • Improved magneto physics so badly worn mags will generally perform worse
  • Added new localizations for aircraft description

Version 1.4.3:

  • Improved support for loading saved flights
  • Fixed repetitive 'tick' in engine sound at around 1,200 RPM
  • Added input configurator support for multiple joystick devices with the same name
  • Fixed typos in airframe and engine maintenance section descriptions
  • Updated hangar aircraft description to match Marketplace release

Version 1.4:

  • Updated sound system to use Wwise interface
