Using a question-and-answer format, Flight Instructor Checkride lists the questions most likely to be asked by examiners during the last step in the flight instructor certification process – the Practical Exam – and provides succinct, ready responses. Instructor applicants will find this App an indispensable tool 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 general refresher material. This Flight Instructor Checkride app is based on the popular Flight Instructor Oral Exam Guide book by Michael Hayes. It is designed for instructor applicants training for the Certified Flight Instructor (CFI) Certificate. More than 1000 questions and responses ensure all the subjects a Flight Instructor candidate will be tested on during checkrides and review flights are covered. Topics include: fundamentals of instructing, technical subject areas (such as runway incursion avoidance, scanning, navigation, logbook entries and certificate endorsements, etc.), preflight preparation, preflight procedures, airport operations, takeoffs, landings and go-arounds, fundamentals of flight, performance and ground reference maneuvers, slow flight, stalls and spins, basic instrument maneuvers, emergency operations, postflight procedures. Answers and explanations were researched using FAA documents (which are identified so pilots know where to go for further study) as well as interviewing FAA examiners. Questions can be marked for further study from any subject to build your own collection of flashcards. An Applicant Practical Test Checklist and the Safety of Flight appendix from the Airman Certification Standards (FAA-S-ACS-25) are also included. Compatible with iOS phones and tablets, this app teaches applicants not only what to expect, but also how to exhibit subject mastery and confidence when under the examiner’s scrutiny. It identifies candidates’ strengths, weaknesses, and gaps in their aeronautical knowledge, which increases study efficiency. App features: • More than 1000 questions are included with succinct, ready responses. • Questions from any subject can be flagged for further study into a separate group. • Includes all the questions and answers from the popular book, Flight Instructor Oral Exam Guide by Michael Hayes. • Brought to you by a trusted resource in aviation training and publishing, Aviation Supplies & Academics (ASA).
