You might try looking under the Federal Aviation Regulations. I'll assume you mean regulations for airlines since you also specified Flight Attendants. That would be FAR Part 121. FAR Part 121 can be purchased relatively cheaply at any aviation bookstore in the U.S. I bet even Amazon carries it.
In fact, a quick check of Amazon show that the 2004 version for Flight Crew is available for just under $7.00.
