Aerobatics: ----------- Once you're this far, you're pretty familiar with the A-10. The exercises won't be described in as much detail as previously, so make sure you know what you're doing. You'll do a loop, an Immelmann turn, a split-S, a barrel roll, and finally a banked variation of a high yo-yo (a more elaborate vertical high-G turn). You'll probably need only the last one, plus possibly the Immelmann and split-S, in combat. They're mostly fighter maneuvers, but performing them will help you get a feel for what the A-10 is capable of. All of these maneuvers are entirely optional; you can fly the missions without using any of them.
