A friend of mine has his UAS operator's certificate and does aerial surveying for agricultural purposes. He normally flies it out in the middle of nowhere but was asked to do a job near an airport. He can complete the job at 100 AGL. The whole thing will take about 30 minutes and he can land the drone or drop it down to 10' AGL in a matter of seconds if there is a conflict with aircraft. The airport in question is KRHP and the field is on final for runway 8. He called the airport and asked to talk to the manager, to explain when and what he was doing and to try and coordinate things. Apparently the manager was not interested or unable to talk to him, but had someone call him back to say he needed a "permit from the county" in order to do the flight. Not exactly helpful and I think that in this situation the FAA/FAR's are what govern these operations. The flight is over privately owned land. Here is what the FAR's have to say on the subject 107.43 Operation in the vicinity of airports. No person may operate a small unmanned aircraft in a manner that interferes with operations and traffic patterns at any airport, heliport, or seaplane base. I am thinking to suggest he file a UAS notam, and have a FAA licensed aircraft pilot with him, keeping visual contact with the UAS and monitoring the CTAF on a handheld, in order to avoid interfering with operations at the airport. I can't find any precedent or guidance on what to do in a scenario like this. Any thoughts?
