A passing knowledge-test score does not mean you can ignore the missed areas before your checkride.
Under 14 CFR § 61.39, applicants must present their knowledge-test report and, when required, obtain an authorized instructor endorsement confirming that they:
• Received and logged preparation training within the 2 calendar months preceding the month of application
• Are prepared for the practical test
• Demonstrated satisfactory knowledge in the subject areas identified as deficient on the knowledge test
That means your missed knowledge codes should become part of a structured review: not a forgotten test report in your flight bag.
Ace Pilot Academy’s § 61.39 Knowledge Review helps organize those deficient areas into focused study and remediation. Use it to identify what needs attention, strengthen your explanations, and arrive better prepared to discuss your knowledge with your instructor and DPE.
This online ground-training resource supports your preparation; it does not replace required instruction, aircraft-specific training, or the endorsement of an authorized instructor.
Review the areas you missed. Understand the “why.” Become checkride ready.
