After many years studying many checklists (including the real one "TO 1A-10C-1"), I have never found any checklist for this aircraft that satisfies me.
This checklist has in mind the actual real panel status when cold starting the A-10C II in DCS. It assumes a perfect working aircraft (so no time wasted in checking obvious things like status lights, etc), while striving for the most real simulation in the steps order.

Please do not hesitate to comment any suggestion, and it will be added if it fits the criteria.
