Query: Inaccurate information

The author makes many inaccurate statements throughout the book.Specific example: The high bypass engine was developed for noise reduction.False. The engine was developed for the needs of the military contractwith commercial manufactures to develop a large transport aircraft (the C-5)in 1965. Noise suppression was a by-product. The FAA was not garnered anypower over noise reduction until 1969. The EPA did not exist until 1972.There are many others.Also, the author gives advice and suggestion how to "beat" a clear violation!Ethically, he is on the same level as a criminal lawyer who attempts to freea guilty party. If you violate FARs, you are in danger of causing a human factoraccident and killing others. You should have your certificate suspended to protect others!As a University professor, I will have to point out the errors to students.I will only use this book for one semester and find another.
