This Tenth Edition of the Instrument Pilot Oral Exam Guide has been updated throughout to comply with current regulations, procedures, and airman certification standards (ACS). Exam Tips have been added to all chapters, and answers and references have been updated to reflect current FAA guidance. New questions and answers reflect subjects evaluators have historically found weak during practical exams. Appendices include a Practical Test Checklist for Applicants and Examiners, Certified Flight Instructor-Instrument Airplane Supplement, and FAA Instrument Proficiency Check (IPC) guidance. ASA Oral Exam Guides were written to help applicants prepare for their oral exams with FAA examiners. Examiners ask a lot of questions during the oral portion of the checkride, and thorough preparation is key to success. Using a question-and-answer format, each Oral Exam Guide lists the questions most likely to be asked by examiners and provides succinct, ready responses. Pilots will find the Oral Exam Guides indispensable tools in both planning for what to expect during the airplane checkride, and mastering the subject matter. Instructors rate them as excellent preparation for students, as well as preps for Instrument Proficiency Checks (IPCs), aircraft transitions, and as general refresher material.
