Definitely! Many pilots have (and passed)! We do, however, recommend that you use our lessons to supplement your own or go through and add/remove/edit the information to ensure you're well prepared for the checkride and are comfortable with the format and flow of the lessons. And the FAA agrees. Straight from the Aviation Instructor's Handbook: "Commercially developed lesson plans are acceptable for most training situations, including use by flight instructor applicants during their practical tests. However, all instructors should recognize that even well-designed preprinted lesson plans may need to be modified. Therefore, instructors are encouraged to use creativity when adapting preprinted lesson plans or when developing their own lesson plans for specific learners or training circumstances." (Page 7-9)
