There are some very good topics scattered about regarding the emergence of FAA "interpretation" and application of regulations. Here's one for consideration. If you have others, here might be a good place to post them. The meaning of "Notify". I was under the FALSE impression that the requirement to "notify" ATC was not a request for permission, but an announcement of intention. Wrong. Check out: https://learn.canvas.net/courses/941/discussion_topics/22554 . This explains that: “Finally, the statute sets a requirement for model aircraft operating within 5 miles of an airport to notify the airport operator and control tower, where applicable, prior to operating. If the model aircraft operator provides notice of forthcoming operations which are then not authorized by air traffic or objected to by the airport operator, the FAA expects the model aircraft operator will not conduct the proposed flights. The FAA would consider flying model aircraft over the objections of FAA air traffic or airport operators to be endangering the safety of the NAS.” . You can certainly object to the FAA air traffic or airport operator's (manager's) decision and run it up the FAA chain of authority, or work with your local RC club to approach the issue in a unified voice, but there is no gray in "...the FAA expects the model operator will not conduct the proposed flights."Important.
