Definition
The section of the Federal Aviation Regulations that establishes Special Air Traffic Rules and Airport Traffic Patterns for specific locations and operations. It contains rules that apply only at named airports, in named airspace, or for specific operations such as helicopter routes, mandatory traffic patterns, and flight restrictions around certain congested or sensitive areas.
Plain English
A part of the federal aviation rulebook that contains special flying rules for specific airports and areas. If you fly into one of these places, you have to follow extra rules that don't apply elsewhere.
Context Anchor
Pilots encounter 14 CFR part 93 when planning flights into or near places that have special FAA operating rules, such as certain busy or sensitive airspace areas.
Derivation
CFR stands for Code of Federal Regulations, the official collection of U.S. government rules. Title 14 covers Aeronautics and Space, and 'part 93' is simply the numbered chapter within that title that holds these special air traffic rules.
Why Pilots Care
Pilots must comply with these additional rules at affected airports or risk enforcement action and loss of landing privileges.
Intuition Check
“Part” does not mean a physical piece of an airplane here. In this citation, “part” means one numbered section of the federal aviation rule book.
Example Sentence 1
Before flying into the Washington, DC area, the pilot reviewed 14 CFR part 93 to understand the special flight rules for that airspace.
Example Sentence 2
Operations at several busy airports fall under 14 CFR part 93 requirements.
