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.
Being an old design, the MD-80 cockpit has what seems like knobs and switches everywhere. This can be a bit confusing and overwhelming for the pilots just starting to fly this bird. One of the most frequently asked questions we get on the support forum is "how do you start it up?". Well, this video tutorial seeks to answer that very question.
I wasn’t really planning on making this a three part series, but based on the response to the two first parts I feel the need to address some of the comments I have received and tidy up a few loose ends, because the big elephant is still in the room.
