Hi.... this is an excellent question and there have been a few threads on this in the past. I also need a checklist for no other reason than to communicate between my darling co-pilot and myself that all is ready. She does some prep work and I do some but we don't want to overlook an unlocked window, an open vent or, heaven forbid, the step still down. We walk through this list together so we can be sure not to miss a thing..So here is the list we find useful....
