Ultimate Checklist P3D4 is a recent tool developed by EEB. It automatically detects the aircraft items status to check if they are correctly or if they are still needing an action from you.
For use with the PMDG 737, the tool needs this expansion. That’s why the requirements specify you must own P3D4, the PMDG 737 and the software Ultimate Checklist P3D4 that is sold separately and not included with the expansion introduced here.
