A whopping 20 PDF checklists! Start-up checklists (long and quick start versions) and almost all air-to-ground weapons and delivery methods (HARMs coming in next version). 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/A-18, P-51, and more being added).
