As its title implies, this book is a good resource for basic aircraft information and the principles of flight. Someone who has little to no knowledge of flying and/or aircraft components will find it useful when studying for the Instrument Comprehension and Aviation Information subtests. There are also two practice AFOQT’s included in this volume.
Review for other important subtests (e.g., Verbal Analogies, Arithmetic Reasoning, Word Knowledge, etc.) is decent but not as in-depth as flight principles. Also, a bit annoying to sift through chapters related to other service tests.
Verdict: Title is true to its name. Not a bad way to spend 12ish dollars.
