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.
With so many aircraft designs flying around, why choose to develop a DC-9 for FSX? It’s a cool aircraft! What more do you need?! Well, actually the logic behind choosing to develop the DC-9 goes a bit deeper than that. I will try to explain.
Today I went plane spotting. I haven't done that in ages, so it was time. Plane spotting is a great pastime. It's fun and relaxing. Besides flight simulation and aviation, I also have a passion for photography. Plane spotting is a great way to combine those two interests!
