My question is about whether I need a part 121/125/135 certificate to perform commercial operation that is not air transportation.
So what happens, for example, if I post an ad to fly over your house in figure eight for you to enjoy for $200 an hour. In this case I'm getting compensated, I'm "holding out" for this operation, but it does not involve carriage of persons or property. If I'm reading the regs correctly, part 119 does not apply so I don't need a part 121/125/135 certificate. (I explicitly picked an activity not covered by 119.1 (e) to avoid potential confusion.) Do I just need a commercial pilot license and can I operate under part 91?
