What do you do when Airports and Heliports private or not don't want to play when it comes to flying your UAS within 5nm? Regardless if it is for recreation or commercial use some airfields just won't talk to you or never answer the phone. In my case, the private hunting land I have access to has areas that touch the 5 mile boundary of a couple small grass private runways. If I follow the letter of the law, I need to notify and coordinate my operations, but what constitutes notification? B4UFly is useless in the sense that it tells you about airports but provides no contact information. Usually I go onto AirNav and get the contact information but more often then not I don't get an answer, sometimes the number is no longer valid. So what's a flyer to do? Recently I was 4.8 miles from private hospital helipad. The helipad contact and owner phone number was the hospital, and I was passed around from person to person, but it seemed like nobody was willing to make a decision or discus it. Since the FAA requires an OWNER and MANAGER for the assignment of an ICAO identifier, does the airport have a fiduciary duty to be reachable?
