ASA has updated the “Aviation Instructor’s Handbook.”
Last updated in 2008, this new edition of the Aviation Instructor’s Handbook was developed by the FAA in cooperation with aviation educators and the industry to help beginning instructors understand and apply the fundamentals of instruction.
Designed for ground instructors, flight instructors, and aviation maintenance instructors, this handbook provides up-to-date information on learning and teaching aeronautical knowledge, risk management, and skills, according to ASA officials.

This book is the official FAA source for teaching flight, ASA officials add, noting many of the test questions for the FAA Fundamentals of Instructing (FOI) Knowledge Exam come from this reference.
The new edition expands and updates the existing material, including scenario-based training relative to assessments, the submission process of an Airman Certificate and/or Rating application through IACRA, and endorsements.
It also incorporates new areas of safety concerns and technical information not previously covered, such as referencing the Airman Certification Standards (ACS) alongside the Practical Test Standards (PTS), teaching practical risk management during flight instruction, and information for remote pilots.
The softcover book is $19.95, while the eBook is $14.95. You can get both in a bundle for $24.95. The book will begin shipping in late June.
Or you can download it from the FAA website for free.
Also available free with a ForeFlight subscription. Just downloaded it.
Sorry, ASA. They’re a good company who’s been around a long time.
