I was recently ask why Coolsky doesn't develop for and support Lockheed Martin's Prepar3D flight simulator. The discussion quickly turned into one about the future of flight simming since P3D is often held up as the future of flight simming. I will try to explain here why I don't develop for or support P3D, and why I don't think it is the future of flight simming.
Failure simulation. This is what in my opinion takes the DC-9 Classic, and all other addons that includes such a feature, to the next level. Usually when you simulate a system in an aircraft, you simulate ON or OFF in a normal state. With failure simulation a system can also be simulated ON or OFF in a failed state. While OFF is usually OFF regardless of state, ON and failed at the same time is where it can get really busy real fast on the flight deck.
Just recently came across an article on the Internet that detailed the differences between the various DC-9 models, as well as the MD-80 series, the MD-90 and B717. I thought it was a very interesting article and I wanted to share it with you.
