Becoming an instructor usually means more than one knowledge test. A CFI candidate may sit the Fundamentals of Instructing and a flight instructor test in the same few weeks, and a ground instructor candidate has tests of their own. Juggling several sets of study material is part of the job.
One thing that helps is that the figure-based questions on the instructor tests draw on a single FAA reference: the Airman Knowledge Testing Supplement for Flight Instructor, Ground Instructor, and Sport Instructor. Practicing with your own copy means the charts and figures look familiar when the testing center hands you theirs.
ASA prints that supplement as CT-8080-5H.
Quick answer: The ASA-CT-8080-5H is the FAA Airman Knowledge Testing Supplement for Flight Instructor, Ground Instructor, and Sport Instructor, the book of figures that instructor knowledge test questions refer to. It’s for CFI, ground instructor, and sport instructor candidates who want to study with the same reference used at the test, available on Skyfarer and at Skyfarer Shop.

Studying for instructor tests
- Work figure questions with the supplement open. Get used to flipping to the right figure quickly.
- Teach it back. As a future instructor, explain each figure-based answer out loud as if to a student; it exposes gaps fast.

Pilot tip: Keep your copy after you pass. The same figures make handy teaching aids when your own students start preparing for their knowledge tests.
