This book has been almost entirely about one thing: how to fly legally. That is precisely Part 107’s job, and § 107.1 says as much — the part applies to the registration, airman certification, and operation of civil small unmanned aircraft systems within the United States, and to their eligibility to operate over human beings. Every rule you have learned lives inside that scope: earning the certificate, the flight envelope, airspace, operations over people, reporting when something goes wrong. Part 107, at its core, is a flight rulebook.

What § 107.1 does not reach matters just as much to a working pilot. The section is silent on the business around the flying — how you form a company, what you charge, how you are taxed, whether you carry insurance, what your contracts say. None of that sits within Part 107’s scope, and the silence is a boundary rather than an oversight: the FAA regulates whether your operation is safe and legal in the air, not whether it is a sound business on the ground. Section 107.1(b) even names whole categories the part does not apply to — air carrier operations, recreational flying under 49 U.S.C. 44809, and certain exemption and Part 91 operations — which is the same idea from the other direction: the rule knows exactly what it governs and what it leaves alone.

For the working pilot, that line is the organizing idea of this closing chapter. Everything on the flight side, this book has covered and can keep current. Everything on the business side — the subject of the sections that follow — Part 107 leaves to you, which means those are questions you answer for yourself rather than look up in a regulation. Knowing which side of the line a question falls on is the first skill of running a drone operation, as distinct from simply flying one.
