توضیحاتی در مورد کتاب :
عملیات عملیاتی و آزمایش پرواز هواپیما در نظر گرفته شده است که به عنوان یک منبع منبع واحد، از تئوری پایه تا موارد عملی، برای صدور گواهینامه آزمایش پرواز و نظارت بر عملکرد عملیاتی عمل کند. این نمونههای واقعی بیشتری نسبت به کتابهای درسی سنتی ارائه میکند. برای این منظور، بخش اول هر موضوع با توسعه معادلات عملکرد پایه بر اساس مجموعه ای از مفروضات آغاز می شود. به دنبال این، ما مانور در حال تجزیه و تحلیل را برای اعتبار بخشیدن به اجزای آن (ایجاد بستههای تست پرواز کوچک برای اعتبارسنجی مدلها و رفتار مورد انتظار هواپیما) تجزیه میکنیم. سپس، ملاحظات تست پرواز از جمله ابزار دقیق مورد نیاز، خطر تست پرواز و کاهش خطر، پراکندگی داده ها، کاهش داده ها و ارائه اطلاعات عملکرد به خدمه پرواز مورد بحث قرار می گیرد. چندین نمونه از نتایج آزمایش پرواز به خواننده کمک می کند تا درک بهتری از آنچه ممکن است هنگام جمع آوری داده ها برای ایجاد مدل های عملکردی با آن مواجه شود.
تمرکز عمده ای بر الزامات گواهینامه FAA 14 CFR قسمت 25 به عنوان مبنایی برای بحث وجود دارد، زیرا قالب این مجموعه مقررات به صورت عمومی در دسترس است و به وضوح موارد اساسی را نشان می دهد که نشان می دهد هواپیما ایمن برای پرواز است. رویکرد کلی همچنین برای صدور گواهینامه تحت قسمت 23 یا مشخصات نظامی معتبر است و هر از گاهی، خواننده با این الزامات اضافی برای نشان دادن تفاوت در عملکرد تأیید شده هواپیما مواجه می شود. در سرتاسر کتاب، خوانندگان مروری بر حوادث و حوادثی که در هواپیماهای مختلف رخ داده است را خواهند دید. هدف این کتاب مقصر دانستن یا مسئولیت نیست، بلکه به اشتراک گذاشتن تجربیات و درس های آموخته شده برای کمک به پیشگیری از حوادث و حوادث آینده و همچنین تغییرات در مقررات برای ادامه بهبود ایمنی هوانوردی است.

توضیحاتی در مورد کتاب به زبان اصلی :
Operational Aircraft Performance and Flight Test Practices is intended to serve as a single source reference, from the basic theory to practical cases, for certification flight testing and operational performance monitoring. It provides more real-life examples than are offered in traditional textbooks. To this end, the first part of every subject begins with the development of the basic performance equations based on a given set of assumptions. Following this, we deconstruct the maneuver being analyzed to validate its components (create small flight test packages to validate models and expected airplane behavior). Then, flight test considerations are discussed including required instrumentation, flight test risk and risk mitigation, data scatter, data reduction and presentation of the performance information to the flight crew. Several examples of flight test results help the reader better understand what they may be faced with when collecting data to create performance models.
There is a major focus on FAA 14 CFR Part 25 certification requirements as a basis for discussion since the format of this set of regulations is publicly available and clearly shows the basic items that go into demonstrating that an airplane is safe to operate. The general approach is also valid for certification under Part 23 or military specifications and, from time to time, the reader will encounter these additional requirements to show variance into airplane certified performance. Throughout the book, readers will find review of accidents and incidents that have occurred on various airplanes. It is not the purpose of this book to assign blame or liability, but rather to share experiences and lessons-learned to hopefully aid in the prevention of future accidents and incidents as well as changes in regulations to continue improving aviation safety.
