I've included this entry in the LOMAC section because the video from Ironhand's excellent LOMAC training series. The concept, though, applies to any flight sim. Watching the video does require that you have Xvid CODECs and a link is available from the website.

"This tutorial's goal is a modest one: to help you understand the concept of corner speed. You will learn what it is and why it's important. In the process, you will learn about energy, turn rate, and turn radius. You will learn what they are and how they interrelate."

It is large, but well worth the time.


Oh, I forgot. In IL-2 you can get an AC's cornering speed from IL-2 Compare v4.07m (Fan Charts), available here:
