I read through your posts and I'm glad to see another eager virtual pilot in the making. The responses you got were very good and I'm just adding this, not to be unpopular or burst any bubbles, but because it's the truth: You'll need to study a bit to fly FS2004 - especially if you want to do it properly.
Most questions have been answered on this forum - do a search for the topic you're interested in (for example "how to land" or some string like that) and you'll get responses and links. Fly the lessons in sequence after *reading* the lessons first. As for FS Passengers, study the manual, but yea it starts from an in-game menu (so you start your flight first).
In conclusion study, study, study. Then, if you have specific questions, please do post them and we'll try our best to come up with an answer.
