Description
“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.”

Features:

• A brand new external aerodynamics engine built with Accu-Sim 2.0 ‘Merlin’ technology
• Remarkable performance accuracy based on operating A2A’s own Comanche 250, N6229P, over many years
• Unparalleled aircraft feel, handling characteristics and trim behaviour based on extensive flight testing
• A complete physics-based per-cylinder simulation of the Lycoming O-540-A internal combustion engine
• Dynamic ground physics featuring true weight on wheels simulation, tyre side-loading and response to different surface types
• Advanced turbulence system and subtle wing flex simulation which responds based on turbulence strength, ground bumps and fuel load
• Sophisticated airframe vibration physics with unique ground roll and engine vibration-based effects
• Authentic fuel system simulates fuel lines, primer, strainers and fuel contamination
• Custom oil system with dynamic viscosity and contaminants that degrade and change the color of the oil
• Advanced engine starter simulation that physically turns the engine through its compression cycle
• Physics-driven sound environment featuring hundreds of dynamic sound effects
• Beautifully-rendered external and internal modelling and texturing with subtle wear effects, dynamic aircraft registration decals and advanced animations.
• Detailed JPI EDM 830 engine monitor with authentic displays and leaning procedures
• Custom-coded Narco avionics stack with NCS812 COM/NAV/DME unit, Mark12E COM/NAV, AT150 transponder, CP 136 audio panel and 841 ADF receiver
• Customisable integration of MSFS default/Working Title GNS 430W and 530W GPS units
• Further integration options for PMS GTN 750 and TDS GTN 750Xi GPS systems
• Century NSD-360A HIS with custom needle-smoothing physics
• Advanced simulation of the S-TEC System 30 two axis autopilot
• Beautiful night lighting implementation featuring multi-purpose dimmable and directable Type C-4A cockpit light, dimmable emissive indicator lamps and white and red lighting options.
• Pilot’s tablet for intuitive interaction with, and management of your airplane
• Interactive walkaround with many moving parts that can be grabbed, manipulated and inspected
• Customisable persistent airplane with failure and wear simulation which can be adjusted and deactivated if desired
• Graphical tablet engine analyser provides a detailed insight into the piston engine operation
