This started as a project many months ago, with the base being the checklists I found on the Flightsimulatior.com forums. The links to those and other sources are below.  I've tweaked and changed things as I've used them throughout many flights using Vatsim and thought maybe someone else could benefit from them also.  

I recommend that you also install DakFly's flight dynamics mod, and the Working Title's G3000 Mod as some of the systems interfaces may be different without them.  

The intention is not necessarily to be 100% true to life, but true to function.  Meaning, while many procedures may differ in the real aircraft, this checklist was created to ensure a smooth successful flight in the simulator as the systems are modeled.

It has undergone at least 5 major revisions since I've started using it, and I expect before it's said and done, I'll make even more.  That said, everyone has their own wants and needs while flying in the sim, so I've included the Word documents in a seperate file so you may tweak or change as you wish.  Also I'll mention, I fly mostly in the US so the radio calls are structured as such.

In the download options there are 2 groups of files: PDF format and DOC format. 

Each contains 3 separate files: A half sheet format, comprised of 3 pages you can print and fold in half(These are pictured laminated and bound above), a full sheet format, if you prefer a bigger checklist or are using a tablet, and a "Night Mode" version of the full sheet format.

Hopefully you find these useful :) Happy flying!
