The CFI ACS Companion

This publication serves as a comprehensive scenario-based study guide designed to help aspiring flight instructors master the FAA-S-ACS-25 standards and prepare for their practical exams. Written by veteran instructor and former Part 141 Examiner, Gary L. Kruger, the text moves beyond rote memorization by presenting real-world instructional dilemmas that challenge readers to apply technical knowledge to complex cockpit and classroom situations. Each section is structured around specific Areas of Operation, featuring realistic scenarios, sample oral exam prompts, and suggested responses derived from official FAA handbooks. The primary goal is to foster professional airmanship and safety culture by teaching candidates how to identify human behavior factors, manage risks, and effectively mentor students. Ultimately, the guide encourages applicants to look at the checkride through the eyes of an examiner, emphasizing the transition from merely knowing the rules to demonstrating the correlation and instructional ability required for certification.
