The PAVE checklist is a check list you should run before every flight to make sure, you as the pilot in command is safe and legal to fly, your aircraft is safe and legal to fly, the environment such as the weather or the airport, amongst other things, is safe and legal to fly, and that you don’t have anyone or any other external factors pressuring you to fly when you shouldn’t.
