CommStudy is THE app for studying for the written portion of your FCC Commercial License exam! Download this FREE app and try out the sample Elements! Each sample contains only 20% of the questions contained in the full Element. If you decide you want to purchase the full Element, this is done via an in-app purchase. All seven elements are included: 1, 3, 6, 7, 7R, 8, and 9. FCC Commercial License exams are composed of questions from a pool. Use this application prior to taking your exam to review and practice all possible questions. Then, test your knowledge with practice exams! Some questions require you to review associated Figures. On the iPad, the figures appear below the question. These figures may be zoomed and panned on the iPhone/iPod touch. After completing your first practice exam, the question pool screen will display your proficiency in each question subelement/topic for all practice exams you have completed. This will help you determine what areas need further study! You may choose to receive immediate feedback on right and wrong answers when taking a practice test or you can wait until the test is completed and review the questions in the Test History section. On practice tests, no question will be repeated until all of the questions have been used in a particular subelement/topic. The practice tests do adhere to the requirements of the actual tests. They are each composed of the proper number of questions from each section of the corresponding question pool. An in-progress practice test can be resumed if you exit the test or the application. This app has these additional features: • Portrait and Landscape support on iPad • Swipe gestures to navigate between questions • Tap on answer to select it • Buttons to skip to next/previous wrong answer in test history • Configurable Test Settings • Optional randomizing of test answers • Optional auto-advance during test

The Oral and Practical (O&P) exams are the last steps for the certification of an aviation mechanic. You will work one-on-one with a designated mechanic evaluator (DME) who will determine if you possess the knowledge, risk management, and skill level needed to be issued an FAA Aviation Mechanic Certificate. This Aviation Mechanic Oral & Practical app will help you prepare for this significant step towards your new career. The app is designed to prepare aviation mechanic applicants to demonstrate their skill and understanding of the required elements outlined in the FAA airman certification standards (FAA-S-ACS-1). This resource includes information on the certification process and covers all the practical skills and required knowledge in a question-and-answer format, with references defined for further study. Using a question-and-answer format, Oral & Practical lists the questions most likely to be asked by examiners during the last step in the Aviation Mechanic certification process – the Practical Exam – and provides succinct, ready responses. Aviation Mechanics will find this App an indispensable tool in both planning for what to expect during the O&P, and mastering the subject matter. Instructors rate them as excellent preparation for students, as well as general refresher material. This Aviation Mechanic Oral & Practical app is based on the popular Aviation Mechanic Oral & Practical Exam Guide, by Keith Anderson. It is designed for applicants training for an Aviation Mechanic certificate with Airframe and Powerplant ratings. Questions and responses ensure the subjects an aviation mechanic candidate will be tested on during the O&P are covered. Questions can be marked for further study from any subject to build your own collection of flashcards. 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: • Knowledge, risk management and skill questions and projects are supported with ACS codes, FAA references and succinct, ready responses. • Questions from any subject can be flagged for further study into a separate group. • Includes the questions and answers from the popular book, Aviation Mechanic Oral & Practical Exam Guide 5th Edition, by Keith Anderson. • Brought to you by a trusted resource in aviation training and publishing, Aviation Supplies & Academics (ASA).
