Hi, a lot of “Checklists” are espacially made for Simulation Purposes and therefore some authors (including me) change some things or just leave some out. Also what in Sim often is called Checklist are in Reallife the “normal procedures”. And there is only one source of the 100% correct procedures and that would be the original flight manual. And than you wil find, that these proceuderes are covered in a LOT of pages. That what in Reallife is called Checklist are just very small safety checks in different stages, where the Pilot and Co-Pilot verbally work through a handfull of items. So these Real Life Checklists are not very helpfull for beginners to learn to setup the aircraft. And even these real life Checklists can vary a little bit from airline to airline.
On my Fenix “Checklist & Procedures” you can find nearly the entire full normal procedures from on original manual - but shortend to get it on a few A4 pages.
Kind Regards
