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.
Multi Crew Experience now fully supports the DC-9 Classic.
Multi Crew Experience is a new add-on to the award winning, Microsoft Flight Simulator X, and FS2004® software. It adds the missing elements, like crew coordination, interactive checklist reading, realistic ATC operation, call-outs and warnings against deviation from standards, as well as extras, like user interface voice control.
