If your new to RealFlight, you Really Must Check Out, the Sticky: Frequently Asked Questions - RF7. Found near the top of the Forum. I consider this a MUST READ, for anyone who uses RealFlight. It's a great source of Essential information. It can answer Questions, you haven't even thought to ask Yet.
Also Note: The RealFlight Manual is located in the Main Menu,(menu at the top of the program) by clicking Help>RealFlight Help.
Hope this helps.
