Following up on my recent article on the DC-9 Classic 2D panel, it's time to have a look at the DC-9 Classic virtual cockpit.
Why do you have to open the pneumatic crossfeed valves to de-ice the wings? Exactly what does the AC bus cross-tie switch do? And why do the engines only draw fuel from the center tank when all the fuel booster pumps are on? The key to understanding these and many other aspects of your aircraft is studying the schematic drawings for the various aircraft systems. That may sound a little bit dry, but to help you out I have included a Schematics section in the DC-9 Classic Flight Center that gives you live interactive schematic drawings.
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.
Avsim.com has just posted another interview they did with me. The previous interview was about me, Coolsky, my partners and products. This new interview is about the DC-9 Classic specifically. I talk about the DC-9 Classic features, what it has to offer and why I think you should have a look at it.
