I was slow to notice this response from JohnBurke regarding an earlier comment I had regarding FAR interpretations. If you are just reading this response, I suggest you look over this (very short) thread and, not withstanding the actual questions, note Johns suggestions on interpretations and explanations that the FAA provides by several means to clarify confusion of intent of the laws related to flight. Just looking over a couple years worth of InFO's or Information For Operators, I found several topics of “stuff” that I either thought I knew correctly/totally and found that my understanding was either faulty or dated.
For anyone in training or standards at a professional flight department/air carrier who is not totally clued into these sources, I strongly suggest you not only become familiar but also, please, share this with your line pilots and help them to maintain currency on the law and the clarifications needed in a changing world.
