I posted this question on the FAA web site, but so far I have not received an answer. I'll post it here to see if anyone here can provide an answer. I fly my done for recreation and have it registered with the FAA. I want to fly within 1 miles of a controlled airport on a search pattern. I will remain below 50-75 feet AGL. How do I notify ATC of my intentions and request permission? I am a licensed fixed wing commercial pilot with a portable A/C radio. Do I call them on the phone, or can I used the radio for contacting the tower? I may decide to fly only hours in advance. So a written request is out of the question. Even if you had permission, I would think it would be a good idea to monitor the tower frequency if operating under these circumstances. I have not flown near an airport yet, but may do so in the near future. If I get an answer from the FAA, I will post it here.
