The ASA version gives answers directly below each question, includes a separate supplement booklet (as you will have with your actual test), gives references to FAA publications, and includes some additional text and background material along with each section of questions.

Instrument Rating questions are arranged by subject into chapters, supported with Answers, Explanations (for correct and incorrect answers) and References. Questions are identified as Airplane, Rotorcraft and Add-On Ratings so you know which to study for your particular test. Helpful test instructions, tips, cross-references, and more included. Includes Instrument Rating, Instrument Flight Instructor (CFII), Instrument Ground Instructor (IGI), and Foreign Pilot Airplane and Helicopter tests.

The Test Prep Series features:
FAA Computer Testing Supplement is bundled with every test book so you will become accustomed to referring to the FAA Figures and Legends as you will during the test. This is the same book you will be issued at the testing center.

The FAA tests are on a one-year cycle, with changes made up to 3 times a year. We make sure you have the most current information by publishing the books in July of each year, posting updates on the ASA website that show changes made to the test questions, and providing a free e-mail Subscription Service for automatic notification when Updates are available. ASA's Test Preps contain the FAA questions and answer stems — plus answers, explanations (for both correct and incorrect answers), references, and FAA Learning Statement Codes (LSC). Chapter text and illustrations help you more fully understand the concepts.

The questions are arranged into chapters based on subject matter to promote better understanding, aid recall, and thus provide a more efficient study guide.
