Hello, I'm thinking about going for my 107 cert. I've been learning to read charts and I have a question. The main area I will be flying is a Mode C airspace radiating out of a class B (Mode C, 30 nautical miles). Would this be treated as a normal Class C space? If I were to do a job, let's say, photographing a house, would I have to give the 90 day notice to the FAA and get permission? Thanks!
