Updated and expanded in its third edition, "Practical Aviation Law", used in conjunction with the "Practical Aviation Law Workbook", serves as a textbook for undergraduate aviation law courses. Used alone, it is an invaluable reference guide for aviation managers, pilots, mechanics, aircraft owners, air traffic controllers, air safety investigators, and others involved in aviation as a profession or hobby. "Practical Aviation Law" provides readers with the basic legal knowledge and perspective to understand how the legal system works in relation to aviation, helps readers recognize and avoid common legal pitfalls, and enables readers to recognize when they need to call a lawyer. The fourth edition has been updated and expanded to reflect changes in statutory and regulatory resulting from the 9/11 event, and a new chapter has been added on airport security.
