Based on Smoothie's Real Life A-10C Punctuated Startup Reference, which I personally found to be a great help in trying to learn the A-10C. As mentioned, this is the Early Access version as of 2-12-2017; if any developments to the AV-8b are made that alter the startup I will do my best to put out an updated version.
A whopping 23 PDF checklists! Start-up checklists (long and quick start versions) and almost all air-to-ground weapons and delivery methods. Abbreviated location information for each step. Great for beginners and people who like to fly multiple airframes and need a quick reference. Sequence based primarily on Chuck's Guides. Look for other module checklists (F-16, P-51, and more being added).
