Pilots Checklist lets you create as many safety checklists as you want. You add the type aircraft you want and the app preloads a generic list of items. You can then add to, subtract from, and rearrange the items to customize the list to your liking. When your done the app saves the list under the plane name you chose for it. You can also print a copy of the list to give to other pilots or to save as a hard copy.
