While the FAA no longer releases the complete database of knowledge test questions, sample questions are released on a quarterly basis and incorporated into our material as appropriate.
Whenever changes are made, they will be automatically incorporated into the course with no input or additional work needed on your end. Thus, you can be confident that this course contains everything you will need to pass your knowledge test with ease.
What is FAA Part 141 Approval?
Under Title 14 of the Code of Federal Regulations, Part 141 deals with pilot schools. These schools are specifically approved by the FAA to teach certain courses in a structured and organized way. The purpose of Part 141 is to ensure the highest level of student training possible.
Gleim sought FAA approval for our Online Ground School course as a means of satisfying the ground school requirement of Part 141 for each pilot certificate and rating. Detailed course materials were submitted to the FAA and approved. For more information, see the Gleim FAA Approval Letter and the Gleim Air Agency Certificate.
The Gleim Online Ground School is overseen directly by the FAA. We are required to provide the FAA with detailed information concerning student success as a result of having taken this course. Our ability to continue to operate as an FAA-approved ground school provider is contingent upon our maintaining the highest quality of instruction possible. This has been the Gleim commitment for more than 30 years, and our FAA approval only further encourages us to thoroughly prepare our customers with the knowledge they will need to confidently pass the FAA knowledge test and operate safely as pilots.
The Gleim Part 141 Online Ground School will only meet the training requirements of Part 141 if your school has the course approved in their Training Course Outline.
