You can use this checklist to keep track of the Private Pilot knowledge areas that you know well and the knowledge areas that you need work on. Use a FAA written practice test to test your knowledge in order to figure out which areas to mark off. This checklist comes from the FAA Private Pilot Airmen Certificate Standards (ACS) which is used by flight test examiners during FAA Private Pilot checkrides as the comprehensive list of what a Private Pilot needs to know and be competent at in order to pass the checkride.
