I think we can certainly agree to that point. But I'm not going to fault them for what they did. There is NEVER anything inappropriate about calling the airport or ATC if you are in question, so on that point we can just agree to disagree. You can ask any controller out there, they'd rather a pilot ask if they are uncertain, rather than just do. I know the airports around where I live appreciate a phone call, whether I'm required to notify them or not by law or regulation.
Yes - we are going to disagree here. A courtesy call to an airport is one thing. A request to an airport manager that doesn't even apply to Part 107 operations, followed by an appeal to an internet forum for an explanation of the confusing answer, instead of referring to the regulations, is quite different.
