Definition
The section of the Federal Aviation Regulations that governs the operation of small unmanned aircraft systems (sUAS) weighing less than 55 pounds for non-recreational purposes in the United States. It sets out the rules for remote pilot certification, aircraft registration, operating limitations, airspace authorizations, and waivers.
Plain English
It is the set of FAA rules that tells you how you can legally fly a small drone for work or business in the United States, who needs a license to do it, and where and how the drone can be flown.
Context Anchor
Seen in drone operating rules, remote pilot training, airspace authorization guidance, and FAA discussions of small unmanned aircraft operations.
Derivation
14 CFR means Title 14 of the Code of Federal Regulations, which is the section of U.S. federal law covering aeronautics and space. 'Part 107' is simply the chapter number within Title 14 that deals specifically with small unmanned aircraft. So 14 CFR part 107 is shorthand for 'the drone rules in the federal aviation regulations.'
Why Pilots Care
Drone pilots must follow Part 107 to operate legally and avoid FAA violations or enforcement actions.
Intuition Check
“Part” does not mean a physical piece of an aircraft here. In this context, it means a numbered section of the federal aviation rules.
