This question book was developed by the Federal Aviation Administration (FAA) to be used by FAA testing centers and FAA-designated written test examiners when administering the flight engineer written test. The book can be used to test applicants in the following flight engineer knowledge areas: basic, turbojet powered, turbopropeller powered, and reciprocating engine powered. The multiple-choice test questions in this book represent a departure from referencing specific airplane makes and models. Instead, test questions are referenced from readily available publications using general questions common to the operation of most turbojet, turbopropeller, and reciprocating engines. Extensive appendices contain background material needed to answer the questions, including 58 figures. (Answers to the questions are not included, nor are they published by the FAA.) (KC)
