Radio navigation is the name of the game when you are flying a DC-9. Radio navigation, like all new things in life, can be difficult to understand at first. But once you have mastered it, it becomes second nature and you will have a much better mental picture of where you are, where you are going, and how to get there.
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.
The Flight Center is the starting point for all aircraft administration, dispatch, options, training and failure simulation. You can also access the Navigation Simulator and the live schematic system views from the Flight Center.

The sound files contained within this package are a bit louder and more powerful than those included in the original DC-9 Classic sound set. While this may not be more realistic than the original sound set, it certainly has a great impact on the overal immersion factor and feeling of being there when flying the DC-9 Classic.
