Infinite Flight has just released a new part of there website dedicated solely to information that will help you get started.
For new and old users it’s a great refresher or introduction to the simulator. The information provided will be expanded upon over time.
Send the website to your friend when you show them Infinite Flight for the first time. They’ll thank you for it. Without it they may be quite lost but with it they’ll be able to get started pretty quickly.
