It is for me and my few friends's personal uses, so copyright will not be an issue here.
EDIT: After reading this to my wife she feels I was too harsh in this post, thus it must be so. That was not my intention so I apologize up front if the tone is less than cordial. I was merely trying to inform a comrade FlightSim developer of the pitfalls of copyright law. I regret that this came across as harsh. That said, I do stand by the dry, unemotional meaning of my statements.
I wish you the best of luck with your project and am happy to see that the forum was able to help on the technical issues - which in fact was the purpose of your posts - a purpose from which I strayed.
Warm Regards, Will

Not quite. For your personal use? You are correct - No problem. Giving to friends - i.e. distributing it even though you are not charging for it? Problem - that is technically a copyright infringement.
Think of it in terms of taping a US football game - in the US the National Football League warning states:
"This telecast is copyrighted by the NFL for the private use of our audience. Any other use of this telecast or any pictures, descriptions, or accounts of the game without the NFL's consent is prohibited."
Tape it so you can watch it later? - no problem - that's private use and you are the audience. Tape it so you can give copies to your friends? - that's not private use.
Yes, I know, there is the "Fair Use" stipulation written into copyright law which means you can use a part of the material as long as it is not a substantial portion and that you give full credit - i.e. using a quote from a publication or a small video clip in a presentation. However, using large sections of commercial imagery in scenery is probably well beyond fair use - even if you give full credit in the accompanying documentation.
That said, I'm not the copyright police - not even a lawyer. I'm just somebody whose former job took him deep into copyright law - I learned it so I didn't go to jail.
Cheers!
